I have a 66cc skyhawk engine when riding at hign rpm the bike starts to shake i have checked all engine mounts all tight?????
Could this be internals???
Could this be internals???
It only started to happen when i made fuel mix richerCould be the rear sprocket...off center maybe?
I made it richer because at hign rpm wouldn't rev out"It only started to happen when I made my fuel mix richer."
Where can you go from there?
Why did you make it richer?
Is it now four stroking?
All bike engines shake when at "high rpm". Maybe you got it to rev just a little closer to oblivion?
PLease can you tell me more about 4 stroking????generally 4 stroking at higher rpms is a symptom of rich condition...
