My 50cc 4stroke engine

50cc 4stroke motor tuned but still under construction and the mixture is not good yet, I didn't find any videos of 50cc 4stroke tuning so here's mine. Setup: big valve head intake 19mm , daytona rotor , 19mm chinese carb ,casual 50cc kit but piston has a little bit less weight, and 4speed zonsheng but diffrent 2de and 4the and r design exhaust

Skyteam PBR is one of the best sounding 50cc bikes in my opinion

+MrFragforce
ja ksnap je,maar dit was een jincheng kopje 12V van een 3-bak blok (deze hebben meestal grotere kleppen ,en de betere namaak van honda ,tegenover skyteam enzo )

Definitely a 24 valve

How much hp ?

[@constant333]

26 ORHAN 26 This motor was never tested on a dyno ,but i have still the crank cilinder ,piston and head laying around.
The power was more moved to high revs ,but still had some torq by the clutch on the crankshaft
