Sorry that i respone late but with the new gearing i got it go 91kmh in hour and it accelerates little bit slowly.and it sounds like the engine makes the noise that it needs more fuel?
i have been also thinking lightening thw fllywheel to get it rev faster but not too much so it will not throw it off balance.
So whats good carburetor?
i have heard good about oko carbs but they are hard to buy in my country.
Will something like mikuni 26mm work or something?
also the needle clip is in the lowest place.
EDIT:I am thinking of good betterer engine.
but now i buy lightened flywheel and if it works for sometime.
I would like engine 140 or 150 or 160 cc and with lot of tuning abilities.[cam big bore kit and all that stuff
