Hi iam 17 and riding a Pulse adrenaline (http://www.chinesemotorcycledealers....F125GY-2B.html) and iam looking to swap the ending to a 250 when i pass my proper test. So iam on here as its running a stock Qingqi Suzuki engine and i thought somone might know a engine which will fit without much (Or any) modification.
Iam going to switch the engine because i like the bike and have grown fond of it in the last 6 months and cannont bear to part with it... ok and that i cannot afford a new one, and because of this, i wondered if anyone knows hown to get a quick performance boost to tide me over for a while?

Thanks Pez

 

I think the dr200se from suzuki will fit in it. Not a big jump up but its something. If you just want to do some mods to your current motor you could put on a pipe, air filter, pistons, valves and many other things. The bad thing about chinese corporations is that if something breaks down on the bike its a very bighassle to get replacement parts and its hard to get those performance parts to match up with the bike.
