so today i finnaly got my bike back together, i put a 50 tooth sprocket on and a kends carlsbad tire 120/90/19 in the rear, along with pro taper bars and grips ! so i go and bring my bike outside for a lil test run, and what happends ? the bike starts for maybe 10 seconds and a puff of blue smoke shoots out, and shuts off. now i cant start it at all !! while my bike was under repair, i decided to do a valve clearance check and it was fine, everything way put together fine by the looks of it ... so can anyone help me ? i hadnt ridden the bike in about 2 weeks or maybe a little more like 3 ... but i did drain the carb and put fresh fuel in the tank ! is it possible for the TPS sensor to cause the problem ? or the hot start plunder ? these are the only 2 things that i thought i screwed up on ..
