HEY, THANKS MINOR, GOT THE PROBLEM SORTED TODAY AS IT CAME TO A POINT WHERE I HAD TO, THIS MORNING AFTER POSTING LASTNITE, I FITTED NEW REEDS AND SPARK .... SO FEW KICKS, NOT PERFECT! BUT BETTER!

IT COULD BE THAT A PISTON RING HAS BROKEN AND SCORED UP THE CYLINDER. (I assume writing only in unreadable Capitals is the new style of forum posts?, Seriously, is your caps lock key broken or something?) But seriously, if anything has gotten into your cylinder through the carb/air inlet that could have scored it up or when the techniwank went pop something might have entered the cylinder. Its also possible that a bit of the piston ring chipped off and scored up the cylinder. Are you running pumped oil or premix? Its possible that not enough oil was in the cylinder and therefore it heat seized and then unseized its self causing all the scoring.
sorry bou the caps lol, and the techniwank went ages before this happened, but the oil is pumped, which i dont really trust tbh, when i fit the 70 kit think im gunna run pre-mix 45-1
If I were you, I would check that oil is acutally getting to the cylinder from the tank, Ive seen this happen a few times now where the oil pump stops working or the tube gets blocked and then the engine heat seizes when someone is riding along, not only that because there still riding the engine unseizes its self and continues running without any oil (Not good!). So yeah, when you convert to the 70 kit, convert to Premix and get rid of the pumped oil system.
