yes she has been dismantled, but the other day i put her back together...
with the redline issue, i started the bike, waited a few minutes while she was running and whilst giving full throttle didnt actually make redline, let her idle then tried again and she did(hit redline).
taking note a new problem has developed and that is when i hit the kill switch the engine kept reving up and up on its own without throttle... thankfully the key off worked.
yes, that was without 2stroke oil... im suprised she didnt sieze either.
i believe there is no scoring on the pistons or inside the cylinder.
