Well i've got a malaguti f15 lc, i use to have a leo tt exhaust but brought a laser xpro. I fitted the laser, but my bike wont move. I've tryed 3,3.5,4 and 6.5 gram rollers but nothing works. It just revs til about 6500rpm then starts moving really slow and stays about 10 mph at 7000rpm. Could it be my clucth springs? Any help ? Cheers
is it a good exhaust? you should have gone with a Giannelli Reverse or something well known...you sure the pipe is on good and not leaking?
