My 2000 is getting a 'freshen up': bored jug, 97mm wiseco , 450 cam and anything that should be replaced/checked will be. I will be replacing all these parts: Cylinder Piston (rings, pin, circlip,) Cam chain Cam chain tensioner ex. cam with 450 cam What else should I replace? How about the cam chain guides? What do I need to check for excessive wear? The bottom end was rebuilt back in 01' or 02' and it got new 2nd & 3rd gears, shift fork and 01' clutch update. Is it time to split the cases again? I seized the motor last weekend and although I'm failr certain the lower end is okay, I only want to do this once and might as well do it now. Thx!
