Hi rob, take your exhaust off and have a look up the port it may help to give you an idea of what condition your piston is in. Try a compression test if you have access to a tester. If you suspect something has defo happened whip the barrel off and have a proper look. Was there any loss of power whilst you were out? :)

The edge of the piston will catch on the powervalve shaft if its been bored out over 1.5mm. Even then, it's close. once the piston has expanded (warmed up), your fuxed. Another issue is the head gasket protruding into the bore. Genuine gaskets compensate for a 1mm rebore, any higher it will need to be trimmed.

Mine is +2mm and i have had to shamfer down the shaft of the powervalve.
