Parmakit W-Force 144cc – Keihin PWM 38 – Big Bertha exhaust

Friday Dennis one of the guys from our Raceteam came to test his high speed circuit racing engine.

The engine is finished with these parts and the results on our P4 dyno were very impressing.

Cylinder: Parmakit 144cc, 60mm bore

Crankshaft: BGM 51/105

Carb: Keihin PWM 38

Exhaust:Big Bertha

This was the first dyno run and the jetting was: idle jet 52, main jet 160, needle DEG. For a first dyno run with probably some room for improvements smiles were all over. With 2.46er primary drive by DRT thisshould be a nice ride on fast tracks like the Nürburgring or Bilster Berg race track.
