could be the battery. probably wouldnt hurt to0 run some sea foam or another good fuel injection cleaner threw it. the sm recommends changing the plugs every 7500 miles. i changed mine at 26k. they didnt really need it then.
how do you bypass the clutch switch? what is needed to be done? im facing this exact problem after adjusting the clutch from the clutch leverSpoke to a mechanic at Kwak dealers today ,and he said bypass the clutch switch they are prone to problems with them which results in the ignition being cut as revs and vibration rise ,said he would put his shirt on it ,so had a spare hour today so did as he said and wahey he's right 85% of the problem has vanished still a bit fluffy off idle and at very high revs but Im hoping cleaning the injectors will sort that out ,hopefully my mind will rest tonight now lol
