Hey guys just a quick question lately ive been out riding and have noticed that after 40min riding the bike start to break up under acceleration. Its fine when i first pull it out of the trailer and ride round for 30-40min dosent miss a beat, but after 40min when you go to open the throttle up it hesitates and pops out the exhaust. nothing else has changed i still run a 35:1mixture same fuel ive pulled the carbs apart to see if i had a blocked jet they were all ok, reeds are all in good nic, ive heard that the coils give problems in them can anyone help me out
cheers
