    One long pipe with the can welded on? I guess it's possible but pretty unusual.... usually there's a joint in there somewhere. If you haven't already, I would take off the plastics and do a physical trace of the pipe and make sure there are no joints.

    I'm not seeing a "cat bulge" at the header pipe on these bikes so I think that the eviro stuff is in the can. Check for a joint there as Carl suggests. If you replace it with a more free flowing one you might have to go up one size on your jet...or not. Being a 125cc you might not have to.

    Hi mate. I also have the same bike. I'm no expert on exhausts so can't be of any help on that front. I've just ordered new bolts for the rear sprocket as one fell off, maybe a good idea to check if you haven't already.

    Hi, i have also just purchased one of these bikes off of my step dad, i needed a cheap run around to get to work and back, and i know he had looked after it. However its sooo slow, does anybody know whether this bike would be restricted, my friends have 125's and they hit 70+mph, i struggle at 55-57mph. if they are restricted how do i go about de-restricting it? thanks
