Mend Peugeot Speedfight Problems Power

peugeot speedfight?

i have recently done a engine change on my 50cc speedfight but it seem to be giving me problems. its like when i try to pull off theres no power there then it finally takes off but as soon as it gets to like 20/22mph it dies a bit and stays at that speed.

plzz could someone give me advice

what type of exhaust does it have on it ?i would guess that you have an expansion chamber race exhaust on it ?if so then the problem is the rollers in the variator are not light enough to create enough revs to get the backpressure in the exhaust high enough to make the engine run right !its a typical problem with these type of pipes im afraid put a standard one on and it will be fine.
