Well, things were going very well. I zip-tied the cams to the cam chain, removed the intake cam and switched the shims as needed. I had numbered each cam cap with perm marker to make sure I put everything back together the same. Got it all back together, cut off the zip ties and rotated the engine by hand a few times. The pivotal mistake I made was I forgot to re-engage the cam chain tensioner, so about the 2nd time around, the camchain skipped in the intake cam. At that point, I had to remove & re-time the cams.
The 2nd problem was the both cam sprockets have the same markings. You have to read the manual very carefully to see that you use the arrows on the EX cam, but use the dash marks on the IN cam. You also need to have the #1 IN & EX valves pointing away from each other with an oil pinhole next to the cam sprocket pointed up & lined up with arrows on the #4 cam cap.
I used the arrows on both cams like on my other bikes, plus again forgot to release the cam chain tensioner, so it skipped again. Start over. Repeat this about 5 times late at night in a cold garage. Maybe I need to move further south... :lol:
It was probably when I was tightening the cams down while mis-aligned that I bent the valves against the pistons. Things didn't feel quite right so I stopped before tightening them down completely, but I think the damage was already done. Luckily, the lower engine was not moving when the damage occurred, so I don't suspect any problems there.
