I am do for a rebuild on my bike. I haven't actually pulled it apart yet to see exactly whats wrong. Just trying to get some info together. Searched and found some answers but not all. 1) It won't start cold unless I bump start it. Valves zeroed out. I was thinking about sending my head out to CRF Heads to have it redone. I was thinking about the $599 package. http://crfheads.com/ How is their work? Another place that you would recommend? 2) While it's apart I was going to do the piston anyway but also because in about 4 hrs run time it burns about half way between the high and low marks on the dip stick. Not much but more than it ever used to. I was going to go with CP piston 13.5:1 stock bore. What is the difference between the standard piston and the project x piston? Also, where is a good place to buy them, I haven't found many places that sell them. Other parts/things to get: Cam chain, cam chain tensioner, 08 cam Any other tips for the rebuild?
