Not really the puch is a 2 stage higher volume chamber much bigger header dia and meant to be used on engines that the power band starts at 8000 and the engine revs out to 12,000!It can be used on a bicycle engine if it's built up to run at high rpm's but be aware the scooters (mopeds) that use that pipe also use a variator to insure that the power band is reached so if your using lower gearing it may never actually get on pipe!
Ok thx!
It's quite possible that you could get it tunned and work well on a modded china girl with trial and error and custom fitting but then you would probably end up with a very short header length to match the rpm range of the engine!
Shorter header? Are you sure? The shorter the header the higher the rpm range for the engine I thought? Aren't our motors best at lower rpms than something like a quality puch would be seeing, especially when tuned up for high speeds?
Yes shorter because you dont want it hitting at 8000 like it's desinged to it would probably be best at 5500-6000 and hopfully pull through to 8000 or more but yea you have to concider the wave speed and distance travelled at lower rpm and less heat for a big chamber!
