I just bought this bike a week ago.this is my street bike ,set up like supermoto. I searched the entire forum ,and found some useful info.Like the guy who has the same problem after installing the electrex wr ignition/lighting coil. I can't find that post(?!)again.I went thru the carb,It is all stock,as is the exhaust ,and the intake. It definately misfires at 1/8 throttle,any rpm,any gear. kind of random too,sometimes alot,sometimes not. it has an electrex light coil. I am begining to think this may be the problem. I tested everything the manual says to and everything is within spec. I hooked up my timing light to check idle rpm,and I watched the strobe,and at the throttle opening where this happens It is dropping spark. so now i feel it is electrical ,not jetting. I am getting confused. Has any one solved this problem?
