I posted back about 2 months ago when my 03 let go. Three intake valve hit the piston and wreaked a bit of havok on my motor. Many of you where very hepful as to try to find the root of my problem. I have had the project on hold becuase I was building a workshop out back and because the snow in Ontario limits my want to ride. Anyways I have found the problem. My camchain was the sole problem and it cost me over $1000 in repairs. Up until this point I didn`t realize the camchain would stretch that fast, but obviously I was wrong. It streched so bad that it shaved an 1/8" of aluminium from the cases up to the head from slop! It also chewed the sprocket on the crank half (part of the crank, not pressed on) so bad that that is why the chian skipped. I would love to show you guys some pictures of the damage so you could prevent it, but I dont know how to upload a photo to this board. I suggest that everybody take out there camchain tensioner and let it come out all the way. Then place it back in to see how much of the tensioner adjustment is left. Trust me, once to tensioner has no more to go, the chain just starts desroying things in it path. Oh yeah my guides were toast as well.
