Which are the advantages of tubeless tires?

  • in case you damaged the tread, air can only escape slowly. The tire remains solid for a longer period of time.
  • no tube, which could burst or be jammed while assembling.
  • in case the tread punches on the rim, there is no tube that might be damaged.
  • if there is an increase in stress on your tire or low pressure making the tire move on the rim, the air valve won't rip off.
  • no tube that might ream by the tire

Split rim - easy assembly

So far, all rims for tubeless tires on the market have been one-piece rims, as for cars or motorbikes.
For classic scooters However, necessary brake drums have limited the design of rims immensely.
This limitation meant that mounting tires on a one-piece rim was hard work and in some cases you even had to damage the tire.

Split rims have always been a strong selling point of Vespas, because this led to quick mountings of tires.

For mounting tires on a one-piece rim, you need suitable equipment, which you will only find in a garage. There is no way to do it at the side of the road.

Pinasco dealt with this deficiency and finally launched a tubeless split rim onto the market, which rejuvenates the advantages of a quick change of tires.

We took a closer look at the new pinasco rim for you.

Colors Vespa alloy rims

Pinasco offers a traditional range of colors. You can buy rims in black, polished alloy and traditionally in silver.

Wheel rim -PINASCO, V2.0, tubeless 2.10-10 alloy, split rims- Vespa (type PX) - alloy polished

Assembling the Vespa rim

First step should be to assemble the air valve. It's easily done with the help of tire mounting paste.

Secondly you should prepare the wider half of the rim with tire mounting paste and put on the tire, starting at the valve.

Please note: your tire may have a profile that is bound to a running direction. This may vary for front and rear tires.

Pinasco KBA 294 rim

If the tire is well placed, the o-ring will find its way to the groove.

Pinasco KBA 262 rim

Once the o-ring is well placed, you can put on the second half of the rim.

Now, both halves have to be linked with 10 screws. Pinasco sets a maximum torque of 18Nm.

Nuts are interlocked in the larger half of the rim. The head of the allen screw is being secured with a schnorr washer, so that it won't open without someone's ado.

Pinasco KBA 260 rim

Fastened by 10 screws, you can now inflate the tire to a maximum of 1.8 bar. You used mounting paste, but the tire won't lie nicely in the rim base? If the entire wheel is fastened to the brake drum you may fit the tire by inflating to a maximum of 3bar. Without the five additional fixation points of the brake drum, it might happen that the two halves of the rim spread, causing pressure to escape. After fastening to the brake drum, this won't happen and pressure is kept reliably.

Pinasco recommends nuts with flange to fasten the rim to the brake drum. When using snap rings for steel rims, the rim was being damaged when unfastening the screws. This won't happen here.

Trace offset

Due to their design, there is a trace offset with some one-piece tubeless rims. Due to the two-piece design of the rim, Pinasco managed to stick to the original rim offset.

Spare wheel

Due to its design and with a small trick you may fasten the Pinasco rim as a spare wheel to your PX. You adapt the bracket for the spare wheel with spacer nuts in a way, that you fasten the wheel “upside down” - valve facing side panel.
This is an example of an LML frame. Having adapted the bracket also makes it easier to get to the valve of a standard wheel.

LML frame

Which wheels fit?

As mentioned before, all common wheels of the sizes 90 / 90-10, 3.00-10 and 3.50-10 fit the Pinasco rim.
In case of one-piece rims it usually used to be luck to find a wheel that wouldn't be damaged during assembly.
You should still pay attention to one small but crucial detail when buying wheels. Your new tire should have the important “TL” or “tubeless” label.
A tire labeled “TT”, meaning tube type, is not necessarily gas-proof.
So please only use “TL” labeled tires with your tubeless rim.

 

Pinasco KBA 302 rim

You will find further information on your new tires in our online manual and on Vespa-Tires.de

Disc brakes

The Pinasco rim also fits vehicles with disc brakes. However, you should check clearance. We installed a PM brake caliper for test reasons. But sadly it didn't fit the Pinasco rim. Standard brake calipers by Grimeca, LML and HengTong (Piaggio) fit the radius of the Pinasco rim without problems.

In case of damage to your tires, you should have the following with you

Your Pinasco rim is fastened by all screws. Should you get embarrassed on the way and need to unfasten your rim, you should have a fitting allen key on board. the key set by Toptul includes all common sizes from 1.5mm - 10mm and the handy box makes it easy to transport the allen keys in the glove compartment without causing noise.

Toptul Allen key

We recommend a repair set for tubeless tires, so that you are able to continue your journey even without a spare wheel.

After removing the air valve you could even install a tube to the Pinasco rim.

New LML frame instead of only a new paint

,

Only giving a new paint to your scooter or rather buy already painted new sheet metal parts

Getting an old scooter freshly painted is rather expensive now. Many painters have already miscalculated the number of parts that need to be painted. There is the malice of the bent style of many frames and preparations often take many hours. This is why a fair paint at €500, if you are lucky, usually is a unique offer. Do you currently need to decide whether or not to freshly paint your scooter? Then this will be of interest to you: new, fully painted frame by LML.

Exceptional LML scooter parts

Vespa LML frame NEW

When we were offered exceptional LML parts, we remained skeptical. It was supposed to be a LML Star and NV 150. In individual parts, which were meant to be assembled in the country of its final destination.

We did some research and took a closer look at its part numbers. Which was exciting. We didn't only discover many small parts but also interesting connections. Some parts seemed to be painted in the same color. We started to get nervous - a very interesting story.

We found out that not only some of the sheet metal parts had been painted in the same color number, but entire sets! All painted parts you need to fully assemble a scooter were packed in an export box: COMPLETE SUCCESS

We agreed terms. Even though we had to take a deep breath first. So many small parts were included in the set. Some of which we will probably never sell.

The LML "NV150", also called "Select", and the "Star" have a good quality. The finish is a little rough sometimes, but they have been produced for the toughest conditions imaginable: the streets of India.

lml-frame-21

Entire set of fully parts of the LML frame

Why should you have your scooter freshly painted, when you can buy already painted sheet metal parts as a set with us?

We offer entire, new Select and Star frames, already fully painted, so that there is no need to expensively paint your old scooter:

Frame set LML Star

We offer the star frames for disc brake or drum brake. Star frames consist of:

  1. Frame (with internal fasteners)
  2. Two side panels (internal fastener)
  3. Rear fender
  4. Tool box with flap
  5. Horn covers
  6. Lower part of the handlebar cover (with support either for drum brake or for disc brake)
  7. Upper part of the handlebar cover
  8. Gear changing grip

The side panels do not have holes for labels, there are holes in the frame for stips and there are no holes in the tool box for a tray for odds and ends. Head sets have a hole in the support for the e-start button.

colors:
We currently have the following colors on offer: pure white, ivory, graphite metallic, orange, silver and black

Frameset LML Select

The Select frames Have a star rear fender and there is a hole in the lower handlebar cover for the handlebar clamp. Select frames consist of:

  1. Frame
  2. Two side panels
  3. Rear fender (Star)
  4. Tool box with lid
  5. Horn covers
  6. Lower part of the handlebar cover
  7. Upper part of the handlebar cover
  8. Speedo bezel (not painted)
  9. Handlebar
  10. Gear changing grip

And again no holes in tool box or side panels. But rectangular holes in the leg shield for floor mats.

colors:
We supply entire kits in red and black for the LML Select.

Only new parts with new paint

There are NO VINs or prefixes. Please check with your responsible registration office whether it is possible to use the VIN of the damaged vehicle for the new frame. You lost the old sheet metal, but you still have the registration documents? Think about alternatives as discussed in various fora online (eg www.Germanscooterforum.de). Vespa lml frame frame set kit

Limited availability

We bought a large amount of parts. However stocks are limited.

Quality

The quality of paint is usually OK but not perfect: small scratches or mini dents will be found on every set.

But the price is all the better: €999 for the Star and € 1,048.99 ex warehouse, Bergheim-Glessen for the Select. This should help in deciding between a new paint or a new frame.

Short fourth gear for Vespa PX and PX EFL

,

Better gear ratio with a short 4th gear

Short fourth gear Vespa PX

Why should your Vespa have a short 4th gear installed?

You install a short fourth gear to improve the gear ratio from third to fourth, which works perfectly fine with a short fourth gear with 36 teeth.
A short fourth gear makes sense for all Vespa PX engines, no matter if you are a daily, tour or race driver.
This drive wheel has 36 teeth, which is one more than the original fourth gear cog of a Vespa PX200.

BGM PRO - Premium tuning parts

The material used for BGM PRO gear boxes are extremely solid. The gear cogs are made from high alloyed Ni-Cr-Mo case hardened steel (20NiCrMo2-2 / AISI8620) to suit highest load levels.
The base material is of very high quality and suitable for the highest levels of engine performance. Surface hardening is precisely defined to HRC 58-60 making the sprockets extremely wear resistant. Always high quality. No compromises.

BGM PRO short fourth gear
Advantages of a short fourth gear:

  • more relaxed driving
  • closer gear step
  • higher gear ratio and optimization of the gear box
Now you can finally have the perfect gear ratio from 3rd to 4th gear!

Gear wheel 4 -BGM PRO- Vespa PX EFL T5 125cc, PX200 EFL (short) - 36 teeth

Short fourth gear Vespa PX EFL Suitable for all gearboxes with flat cruciform. How to recognize these gearboxes? The driveshaft has a locking ring fitted in the front of the gear cogs.

Gear wheel 4 -BGM PRO- Vespa PX (-1984), PX200 (short) - 36 teeth

Short fourth gear Vespa PX (-1984) Suitable for all gear boxes with bended cruciform. How to recognize these gearboxes? The driveshaft has a locking ring fitted in the front of and behind the gear cogs.

The middle part lies on the cruciform. Measurements:

  • PX old type (until 1984, bent cruciform): 5mm
  • EFL (since 1984, flat cruciform): 6,5mm

Middle parts of BGM gear cogs are larger (approx. 1 / 10mm) and therefore the contact surface for the cruciform is larger.

Scooter Center technology TIP:

A short fourth gear can be perfectly combined with the 64 teeth primary drive wheel by BGM Pro, which has a longer reduction. Using a 24 teeth clutch sprocket significantly the total gear ratio, but decreases the gear step from third to fourth, turning the entire engine performance into speed.

BGM PRO short fourth gear
Advantages of a short fourth gear:

  • more relaxed driving
  • closer gear step
  • higher gear ratio and optimization of the gear box
Now you can finally have the perfect gear ratio from 3rd to 4th gear!

When working on a gearbox, don't forget:

Particularly interesting

So far, Malossi sports and Polini 221 engines, which are high in torque, have proven their quality in combination with a 24/64 gear ratio and to short fourth gear. BGM6536L

A short fourth gear reduces the gear step between third and fourth, in order to grant a sufficient torque and smooth gear ratio and nice acceleration when changing to fourth.

The table and graphs below show the difference. Higher reduction leads to nice cruising speed in towns and on large roads at lower gears with very low revs. This combinations offers rather quick driving and a higher top speed with lower revs when driving in fourth. 24_64 graph

Primary reduction BGM PRO Vespa Largeframe

, ,

Higher primary reduction for a higher performance of Vespa engines

New concepts for performance and torque oriented engines in the Vespa Largeframe segment almost demand the use of a higher primary reduction.

A higher primary reduction increases the torque available in your engine, increasing effective use of the available torque curve. This means you will cruise at constant speed at lower revs, which in turn means that there is an Increase in top speed.

BGM PRO primary drive wheels
Advantages of BGM PRO higher primary reduction for your tuned engine

  • more relaxed driving
  • Less gearbox noise
  • Less fuel consumption
  • higher top speed
  • A short forth gear even increases acceleration at higher speed
  • a larger coverage of tooth flanks leads to higher resilience
  • lower revs
Vespa driving with a higher primary reduction: increase in speed, decrease in noise and consumption!
Up until now you could only purchase spur-geared primary reduction gears. Resulting in immense driving noises, less coverage of tooth flanks and the fact that a later change of gear reduction will demand time, money and material. This decreases day to day efficiency.

NEW: Smoother operation and symmetrical power transmission by BGM PRO

BGM PRO primary drive wheels are helically geared. Compared to spur gearing, helical gearing leads to a drastic increase in smooth operation and an increase in smooth power transmission at tooth flanks.

BGM6565 (2)

Certified quality by BGM PRO

Each batch of primary drive wheels is checked for its dimensional accuracy, quality of material and workmanship, just like our clutch sprockets and gear cogs.

Wide range of combinations possible

We are currently the only manufacturer offering helical gearing reductions, which can be used in combination with various clutch sprockets.

The following combinations are possible:

Primary drive wheel BGM BGM6564 Primary drive wheel BGM BGM6565 *
Number of teeth 64 65
Clutch sprocket BGM Cosa BGM6522S 22 2,91 2,95
Clutch sprocket BGM Cosa BGM6523S 23 2,78 2,83
Clutch sprocket BGM Cosa BGM6524S 24 2,67 2,71
* or Piaggio original

 

Vespa clutch sprocket BGM PRO with 22 teeth

Vespa clutch sprocket BGM PRO with 22 teeth is a special sprocket though. Base circle and tooth flanks were optimized for primary drive wheels with 65 and 64 teeth. So, in combination 22/65 the BGM PRO clutch sprocket offers a more stable and better coverage of tooth flanks than sprockets by Piaggio or Newfren for instance.

Perfect fit: BGM SUPERSTRONG clutch

Our BGM Superstrong Vespa clutch has the fitting sprockets and is easily fitted to BGM primary drive wheels. BGM8099D

The table shows the various combinations and their effects on the reduction ratio. It helps to choose the perfect gearbox for any event. A combination of a long distance primary drive wheel with 64 teeth and a clutch sprocket with 22 teeth will lead to an overall reduction that is lower than in an original PX200. Meaning: You can choose between various exhausts. Either high revs or a lot of torque.

Vespa primary drive repair kit

We recommend to use our reinforced primary drive repair kit to fit primary drive wheels to the layshaft.BGM0195F44

Its reinforced springs also work perfectly with a dramatically increased torque.

Short fourth gear for Vespa

So far, Malossi sports and Polini 221 engines, which are high in torque, have proven their quality in combination with a 24/64 and a short fourth gear.BGM6536L

A short fourth gear reduces the gear step between third and fourth, in order to grant a sufficient torque and smooth gear ratio and nice acceleration when changing to fourth.

The table and graphs below show the difference. Higher reduction leads to nice cruising speed in towns and on large roads at lower gears with very low revs. This combinations offers rather quick driving and a higher top speed with lower revs when driving in fourth. 24_64 graph

Conclusion

A higher primary reduction offers

  • more relaxed driving
  • higher top speed and
  • A short forth gear even increases acceleration at higher speed.

Vespa transmission shimming - really easy - instructions

, , ,

Shimming the Vespa transmission made easy

In order to be able to adjust the sprocket free play on the main shaft you will need the corresponding transmission shims and two thickness gauges (you really need them twice) for measuring the transmission.

vespa-gear-distance-feeler-gauge

It is best when you begin in first gear with a standard shoulder ring measuring 1.0mm so that later on when everything is mounted the gears stay firmly in place and you can properly shift the transmission into the neutral gear.

BGM6020 004

Starting below the first gear using a shoulder ring that is too thick could cause the gear selector cruciform to no longer be in a free position between the sprocket segments and make it want to engage the sprockets in the neutral.

BGM6020 015

Therefore it is wise to first of all place the necessary shim behind the fourth gear. BGM6020 002

Checking the transmission free play

You can now check the sprockets' free play using the thickness gauges.

After mounting the parts the free play should range from 0.05mm to 0.15mm. In transmissions that consist entirely of new components you should rather opt for a tighter free play because the components have yet to “adapt to one another”. BGM6020 006

Don't choose too little free play

What you shouldn't do either is overdoing it and allowing too little free play. This will result in the contrary to what you want on a running transmission. The hardened surfaces of the sprockets and shoulder rings tend to chew in, hence drastically increasing the free play within a short period.

If you want to replace individually sprockets of your transmission, we recommend that you order a set of shoulder rings ranging from 1.0mm to 1.3mm right away. And while you're at it anyways, have a look at the gear selector cruciform. Don't try to save on oil transmission and replace it - and don't forget to use new O rings.

The right tools in good quality for your scooter will always help you do the job.

Details on the optimized 26 SI carburetors

With our carburetor tuning Float chamber cover, nozzle holder and holes professionally edited.

In detail, the hole for the float needle is enlarged to 2,8mm and the guide for the float needle is provided with two additional holes for faster fuel supply.

The 5,2mm float needle is spring-loaded and helps the float needle to have a longer service life - it has to interrupt the flow of fuel several thousand times an hour and then release it again.

Fast and constant spray supply up to 180 main nozzle

The enlarged valve bore In the float needle seat and through the additional holes in the guide for the float needle, the fuel flows in unhindered. This means that the fuel level in the float chamber remains constant.

So that the fuel can flow sufficiently quickly to the nozzle assembly, the bore from the float chamber to the nozzle assembly is enlarged from 1,2mm to 1,8mm. This diameter is with a 180 Dellorto main jet equate - this nozzle size can also be used if required.

We are currently not aware of any engines that require a main jet in the region around 180. The Fasterflow therefore still offers reserves in this area.

Touring setup with 25HP with main jet up to 160

In current touring engines with approx. 20-25PS, main jets in the range of 135-160 are often used.

Leaning during the acceleration phase or swallowing due to lack of fuel during load changes are a thing of the past with the right nozzle equipment.

25s are the better 26s SI carburettors

On closer inspection you will find that the carburetor marked as 26/26 has an effective bore of 25mm.

SI Faster Flow 041

 

Vespa SI carburettor with a bore of real 26mm are prone to premature, high wear in the area of ​​the slide guide. Once this sensitive area is worn out, the carburetor is unusable.

Due to the small overlap of slide and guide with a 26mm bore, additional air can cheat past the slide in the worn areas of the guide and strongly influence the running smoothness of the engine.

This goes up to the involuntary revving up while idling and noticeable emaciation or lean jerking when accelerating.

Therefore the bgm PRO 26er SI - carburettors are provided with an optimal effective bore of 25mm.

Together with our bgm PRO Faster Flow fuel tap the revised carburettors are a perfect system for a reliable fuel supply.

Details for the Polini 221ccm Vespa PX tuning kit for 60mm stroke cranks

, , ,

We had a closer look at the new one Malossi Sport and MHR cylinder kits earlier. Now we check the new Polini 221 cc cylinder kit that is supposed to be used with 60 mm stroke crankshafts.

The cylinder head is the one that is used on the Polini 210cc as well. So let us have a look at the compression ratio of the head that is used with both kits.

Once the long threaded spark is fitted the head is tight enough for it's closer inspection. To have our Plexiglas high tech measurement equioment sealed properly too with put a little bit grease on the head's gasket surface.

Cylinder head Polini221

With Plexiglas plate attached we fill up the combustion chamber with oil to get the volume of the combustion chamber.

Cylinder head Polini221_2

With 25 ml putted into it, we have a 25 cc combustion chamber volume.

To get the complete combustion chamber volume (Vc) we need the volume of the curved piston dome. With a freely selected recess of the piston we can calculate the volume above the piston. We have the piston recessed by 6 mm here.

piston head polini221

6.85 x 6.85 x 0.785 x 0.6 = 22.1 cc is the volume of this area.

Sealed with grease and filled up with a light oil we see 14.6 ml (= 14.6 cc). So we have 22.1-14.6 = 7.5 cc for the volume of the piston dome.

To get the show complete we know need to have a look at the squis area volume. This needs to be measured at the engine with the parts like crank, barrel, piston and head mounted. We measure a 2.2mm squish clearance. This gives a volume of 8.1 cc.

So we have a combustion chamber volume of:

Cylinder head 25 cc

+ Squish clearance 8,1cc

-piston dome 7,5cc

= 25,6cc

This gives a compression ratio? of

Cylinder 221 cc + combustion chamber area 25,6 cc / combustion chamber volume 25,6 cc

= 246,6ccm / 25,6ccm

? = 9,63

So slightly higher compression ratio then the Malossi with? = 9,3 (on a 57 mm stroke engine!)

This is the Polini 221 engine of a customer.

Polini 221cc, Crankshaft Polini 60mm stroke, Dellorto PHBH 28, Polini inlet manifold for rotary valve and with our bgm BigBox. With a standard base gasket there are port timings of 120 ° / 170 °. All details are written in the diagram.

Polini221

This is a plug and play engine with no further porting. And one has to admit that 26 Nm of torque are lots. Especially if they are so low down in the power band.

At 4.000 rpm we have 20 Nm this is double the torque a standard P2 engine has at peak.

Depending on the preferred riding style and for what the scooter should be used too, a taller gear ratio makes sense to not over-rev the engine all the time. The very well balanced and smooth running Polini crankshaft is a perfect companion for traveling as well as street racing ...

This engine setup and a longer gear ratio should give an engine that should sit for long distance travells easily at 120 km / h. Here ** as an example with an original gearbox, compared to our bgm bgm Superstrong clutch with DRT sprocket with one tooth more and the original primary drive of the P2 with 65 teeth.

PX200 24_65

With 20 hp at 7.000 rpm it should be easy to do the often quoted 120 km / h mark.

** The "GearCalc" Calculator was given to use from GSF member Motorhead. Cheers!

Vespa exhaust Exhaust bgm PRO MB Big Box Prototype

MB & bgm Vespa Big Box exhaust - update

, , , ,

Vespa exhaust bgm PRO

Our exhaust manufacturer has delivered the first samples made after the sample developed by Mark Broadhurst. We received samples for the P2 as well as for the 125 and 150 P-range engines.

First sight: Well done! Optics and machining as desired. Thick, solid made, shape of the U-bend spot on and the measurements of the exhaust bushing is right too.

If it proofs itself at the dyno, the manufacturer could start. A delivery date within this year could easily be done.

For testing we had these engines:

All dyno runs were done on proper warmed up engines. The comparison is against the exhausts already fitted to each scooter and against SIP Road exhaust.

Nearly all scooters were used on the road afterwards to see the changes done to the power characteristics in the real world too. And all the riders were happy how the engines transformed and were much faster and easier to ride.

upshot: Production can be started!

Cylinder Polini 221 Alu Vespa PX200

Polini Aluminum cylinder with 221cc for Vespa PX200

,

Polinis project to launch the well known 210cc aluminum cylinder for the PX as a long-stroke version (as reported), is finally in the last steps.

Cylinder Polini 221 Alu Vespa PX200The new cylinder, which is presumably similar to the existing 210cc cylinder (but with a long aluminum bore), will be available with a special cylinder head to fit the stroke of 60mm. For further details such as steering angle, compression and performance data we will keep you posted as these information are not known yet.

The cylinder head will also be available separately. According to Polini this head will also fit the existing aluminum and cast iron versions with standard stroke. We will see how this is achieved and what head will look like.

The performance of the current 57mm stroke aluminum version can be found in our earlier blog reports here:

Polini 210 Alu Plug & Play

Polini 210 with conversion

A special self-made long-stroke version has been tested here:

Polini 230cc

We expect that the new version will have an even broader performance than the 210cc variant, as the angle bound will automatically grow through the use of a 60mm stroke crankshaft. This would certainly result in an engine concept for everyday use with lots of torque from low engine speeds, a strong middle performance and a sufficient rotary power for the highway. All without the balancing act of the old thermal cast iron version.

Polini also wants to offer an own designed crankshaft for this cylinder kit:

Crankshaft Polini PX200 60mm stroke for aluminum cylinder 221ccmPolini speaks of a well balanced shaft. Here again, we will post all further information as soon as we receive it and have verified it ourselves.. The suggested retail price of Polini is around 290Euro

The cylinder will of course also run on any 60mm stroke crank. A high quality and significantly less expensive alternative is our bgm PRO crankshaft which has been proven in quite a few very powerful engines

Crankshaft PX200 Lagnhub 60mm BGM pro

With a selling price of 179,99 € our bgm crank it will be much cheaper than the polini version but regarding quality it will be similar and has proven its power already in many existing setups.

Conclusion: Polini makes again a big step forward regarding its leadership in terms of product innovations in the kickstart scooter market. While rival Malossi currently limits their ideas to changing names of already existing products, Polini shows what they can provide with a little more courage and innovative spirit.

The selling price of the new cylinder will be a little higher than the current one 210cc cylinders as the head will be included in the new kit.

Cylinder and shaft together will offer a strong touring package that will probably have around 20hp.
What do you need more?

Surely one of the loveliest inventions for the PX200 since our BGM Superstrong Cosa clutch...

Polini 210 on our P4 dyno

, ,

Today we had a real beauty on our Dyno. A Vespa Rally 200.

The aim of this project was to get a tractor torque engine for daily driving.

Base what a vespa PX200 motor, the rotary valve in the housing has been expanded for more discreet inlet angle before TDC. Crankshaft is genuine PX200 crank with 57mm stroke.

The new 210 Polini is filled by a Si26 carb With Polini induction funnel.

because of the Polini induction funnel the available torque in the lower rev range stands out very clearly. The same engine with a Malossi cylinder without the Polini funnel is “missing” almost 4Nm in the same rpm range!

The alloy Polini is supported by a SIP Road exhaust.

From idle speed the engine has proper torque and power.

15hp and 23Nm from 4500 rpm speak for themselves.

With a taller Primary gear the torque can be stretched and relatively high speeds can be achieved at low rpm.

Nice setup!

Alloy Polini 230cc Big Bore Vespa P200

, ,

As mentioned earlier Polini is going to release the alloy barrel for the 200cc casings for long stroked engines later next year. The Polini 210cc alloy kit can be used with a 60mm stroke crankshaft, but you are limited in doing so because of different reasons. The kit contains a oiston with the top ring in L-shape. This type of piston rings runs to the top of the piston.

 

If you are going to use a longer stroked crankshaft eg 60mm instead of 57mm the 3mm longer stroke needs to be equaled in one way or another ...

With the piston running 1.5mm in each direction (top and bottom dead center) the barrel needs to be 1.5mm longer. Normally this is equaled by a base or head gasket.

With a two stroke engines power determined by the port timings, this can cause headaches or been seen as the perfect way to get the tune on barrels sorted to one's needs. With the port timings as a trigonometric function, the transfer timings are altered above average. The timings of the transfers and exhaust should always be in a certain level to work properly.

With the Polini as it comes you can use a base gasket only to equal the stroke. With a head gasket the L-type piston ring could cause trouble by running at least partially out of the bore. Is a base gasket used the port timings are raised about average and the blow down timing is heavily affected. Limiting the power up the rev range.

To achieve the good and torquey power output that the new Polini kit has out of the box, a head gasket is recommended to for te right timings. But there is the L-ring prob ...

Facts ...

Out of the box the new Polini has port timings of 123 ° transfers to 171 ° exhaust timing with the 57mm sickly. One of the best kits out of the box for touring and good power low down.

If you are going to fit the kit with a 60mm sickly and simply use a 1.5mm base gasket the port timings are changed to around 135 ° / 179 °.

If you are looking at the bow down timing only it is changed from 24 ° to 22 ° only. If you look at the 22 ° this would be still okay for a broad power curve. But if you have a look at the changes of the port timings the 135 ° transfer timings is far away for a road going engine. This crap design can be used with an exhaust based on the original design to make it work. So a Site Plus or SIP Road would be the ones to go for.

230cc ???
One of our customers (Thomas aka schoeni230) had a full go on the Polini alloy barrel subject. He is using it with a custom made 62.5mm crankshaft.

With a special piston instead of the standard Polini L-ring item the problem with the L-ring running out of the bore is cured.

This piston makes it possible to have the piston running out of the bore to a cretain degree:

 

 

 

 

 

 

 

This way a 0.4mm base gasket was sufficient to get everything right. Even with the longer stroke of 5.5 mm the port timings were nearly in a reasonable area.
With ~ 133 ° / 179 ° and a special cylinder head to cover the longer stroke the engines runs pretty well with an exhaust based on the PEP Big Bore design. The high torque and a really broad power band makes it a really good rally going engine with high top speed under every circumstance. And the top power output is -with the design of the exhaust in mind-stunning as well.

The carb used is a 35mm Keihin PWK with a scooter & service Reed manifold (with V Force Reeds). The ignition is one of the Vespatronic those.

The barrel is nearly untouched. The exhaust port was altered only. The width and height were slightly increased.

UPSHOT:

Even with the port timings on the strange side, the engine should be best of all worlds and really catches one's demands for a strong road going engine. With more than 20hp beyond the 9k rev mark.

One weak point for sure is the piston running out of the bore. Giving alignment issues of head to bore and the thermal thing at the sides of the piston are an issue as well.

The upcoming Polini for the 60mm crankshaft should be a massive step to built one of these dream engines without the need to cut so many corners.

If you are fancy this NOW, contact us. We are happy to give you advice on how to built a similar engine with the 60mm crankshaft.
