I am going to be completley going through my 2002 426f. I am thinking of doing the 2003 450 cam upgrade but i am concerned with reliability. After reading alot on this forum, I know people love the upgrade, but i am really concerned as to how it will affect reliabilty. Apparantly there is a slight difference that will cause abnormal wear over time. I am a pretty biy guy at 6'2 and 240 lbs and can usually start the bike pretty easily. however i seem to stall it at low speeds and would love to be able to get it started as easy as possible .. Can anyone chime in??Also, what do you do with the decomp lever???
