Had my sled out the other day all i could hit was 70mph and the tach would only go up to about 6500 also seemed to load up when idling.
when i got back i cleaned the carbs put in the original main jets back in they are 290 took it out after that and the bottom end seemed alright but there was a power loss in the mid and high end now i noticed before i was having problems with backshifting .does this sound like a clutch problem any help appreciated
