Could be a bad intake valve. Run a compression check.

Prior to running the bike I set the timing manually with the ignition plate.  After it started the timing light showed good on all 4 cylinders.  I am starting to think that this happens a lot because you wouldn't notice it till you pulled the airbox off or ran the engine with the airbox off.

Thanks Ray.
