[QUOTE="jimsowen, post: 189118, member: 2701"] The photo of the plug was after a 4km Idle home when the bike stopped I checked the plug and it was light grey. I read a 220 page book about two stroke performance tuneing by grayham bell. I thing the problem is thst the shop hasnt machined tge head properly for the correct squish tolerances and didnt cut away the centre section which in turn has raised the compression ratio far too much and the engine is getting too hot and and suffering from detonation from overheating and causing a vapour lock in the cylinder wich is preventing the fuel from enttering the combustion chamber and starving the engine. I no expert but could this be the case BIG ??? [/QUOTE]
