Hey Lads,
Havent even got my ride and Im looking to make it go quicker.
Is anyone up to speed on what go fast aftermarket gear will fit on these 250 China bikes???
The bike claims 13.5kw @ 8000
How does this compare to your monsters, as most of the top brand 250 what start at 30kw wouldnt they?

Was thinking just Hi flo filter and exhaust to start with...other ideas?


cheers

good luck finding any real performance parts for anything chinese except for those with pit bike type engines.

13.5kW = 18.1PS which probably about an average claimed figure for most air cooled 250 4 stroke engines.


30kW = 40.2PS and that is about the average starting figure for most of the japanese 450's

seems to be a few bits & pieces to make the motors go but at pete said not too much in they way of hot up parts except for thumpstar bikes
Good start is air filter you will probably have to rejet carb, take inlet manifold off and port match it and clean up the seam inside
hope this helps

You also need to match the carby to inlet manifold
once run in check tappets & all bolts not only on motor but whole quad

I know match porting head wont make it a rocket but every little bit adds up
