Beating a dead horse I think, but from all the research Ive done, our transmissions are completely different than whats in a car. They ARE constant mesh trannies, and personally my shifter doesnt feel ANY different if I have my clutch in, or not. I NEVER shift with a clutch, I use it to start, stop, and negotiate tough terrain. People I know that have been riding for YEARS never use theirs. Not even for downshifts.
So for me, Ill continue to NOT use my clutch. I figure it isnt hurting the tranny any more than using it, and its saving me money because I dont have to change it as often.
