From what your saying it could be a broken valve. Did you ride it home ? Take some pictures of the valve. Do not run the bike. Pull the spark plug and look for carnage. Report back.
Alright.....
I pulled the cam chain tensioner bolt off, slipped the camshaft bearings off, and pulled the cam on out.
There appears to be some slight pitting on the side of the risers, any idea of that will cause problems???
On a side note, the bearings on the left side did not want to come off, I ended up having to hammer on them a bit.
I secured the chain, and pulled the rest of the head off (not sure about the correct terminology )
The pistons look nice and grimy, so I don't think I have any oil leaks to worry about.
I can't see anything obvious with the left side exhaust valve
I'm planning on borrowing a valve spring compressor from autozone. Anyone know which would be the best?? http://www.autozone.com/autozone/ac.../Valve-Spring-Compressor-and-Measure/_/N-4aow .
Scabber - I am absolutely certain that I was adjusting the exhaust valve on while at TDC of the exhaust stroke. I at least triple checked running through the cycles & very carefully stopping at TDC each time. How would I have been able to tell if the valve was bent/broken form the pipe hole?
