Hi, the bike sounds OK but obviously the heads are gonna have to be whipped off for a butchers. I've heard from a reliable source that the pots can glaze with hard use and cause this problem... Any ideas peeps? Cheers.
Turned out to be a cracked piston... And the crack had propogated right through and round the gudgeon pin bosses.... Yikes! Nearly lunched the complete engine.

Unlucky to have such a fault, but very lucky not to do some serious damage
