thanks. the bike's not fully run in yet but once it is, or come springtime, i'll give this a shot. my only concern would be how this would affect the exhaust pressure at the valve/cylinder and whether it could be detrimental to the engine?
also, do you know what effect it would have on the engine if the fuel mixture was adjusted to be richer. will it make the bike a little more gutsy, or is it just likely to make it run too hot and cause problems? i'm led to believe that when these bikes arrive new the mixture is set very thin in order to give the bike better emmisions results for import purposes
lastly, how obvious is it that i'm a newbie to biking?

most chinese bikes have restrictors fitted inside the exhausts.remove exhaust pipe and see if it has a skinny exhaust pipe inside that one.
