Okay, so I have my 2002 CBR 954 stripped down to the motor and before I begin reassembly, what would be the best to do to the motor since I have access to everything. I was thinking replacing the cam chain tensioner since I hear its a bitch to get to and a valve adjustment since it would also be easy access. Now take in mind that I have never heard this motor run. The guy I got it from said it ran fine and he parked it for the winter and when he went to start it the next summer it would only crank but not fire. He thought it was an electrical issue and ripped out the wiring harness and a few other things, so I basically picked it up real cheap as it was a basket case. It does crank over so I was thinking of also doing a compression check while I'm at it. my goal though is to avoid ripping into to much of the motor.
