Yes, I would agree, 1 mm would be just shy of .040" and that is a lot on an engine that already has pretty high port timings. You can put a degree wheel on it but I bet the exhaust timing is going to be greater than 185 deg. and that is high. May be time for a new sleeve/piston if it has been cut too far. [8D]

Good luck getting it figured out.
