I purchased the ยด01 and after 3 months and 300 miles I have went through three different shops.NUMBER ONE AND TWO pipes are not getting hot. yet I have spark on all cyls.When I get the bike back, they tell me that my carbs were dirty and I needed new plugs. Then the bike seems to run good that day { exept I think it runs a little rough in first gear @20mph} and then you let it sit for two days and the same problem is back. I think the problem is fuel related, on the other hand, could this be a coil or ignighter problem ? My bike is modified with a header & k&n pods with jet kit along with 13,000 miles. should I just junk it or keep throwhing money at it?
