Over the last couple months my '01 XR650R has become harder and harder to start. The last ride I finnally had to use the Yamaha pagan starting ritual from the YZ400/426. Well it is on the cold side and I have some free time so I decided to tear the bike down for heavy maintenance and see if I can figure out what is up with the decompressor system. I have not pulled the cam out, but I have opened up the top end. It seems that the spring under the decomressor cam has failed, I can move the decompressor cam up and down and it stays where I leave it. Checking the Service Honda parts fiche, and with my local dealer the spring is not listed anywhere. But on page 8-9 of my trusty service manual they talk about it. AARRGGHH!! So as I see it I have two options at the moment. Leave it alone and live with it, or pull the cam out and either remove the spring or try and frind a replacement from someone other than Honda. Any thoughts? Is there a chance the spring could come out and trash my top end? Thanks for the help all! P.S. If I had the cash I would look into either a Stage 1 Barnums or HotCam.
