Question Hard starting Bird--update

Morning guys, I couldn't try 12 minute tune because the bike wouldn't start I took it tto the dealer and they checked it out. Problem: low compression. They pulled the cam cover and found tight intake valves. After removing all the bucket shims they still have no clearence. Very strange. The bike seemed to run normally the last time it was ridden other than needing throttle input to start.
The only explanation I can come up with cam saddles in the head have worn excessively or valve head or serious valve seat deterioration
They will be pulling the head early next week. I am looking forward to finding the answer to this problem. Will update when I have more info.
