Hi everyone, I'm having a problem with a 1965 li 185cc I restored in 2001. I have been though the scooter and upgraded a few years ago but this year I had what seemed like a seizure ( top End ) as when I inspected the piston there was some heat burns at the wrong side of the rings. I replaced the piston and had the barrel with piston inserted inspected by a motorcycle mechanic and it seems the barrel is fine. The problem is when I assembled the scooter the kick is just slipping. I checked the clutch which was a little tight and the problem still remains. Can anyone help me out here? I have taken the piston out again and it still looks fine. The root cause of the delinquency is that at the top of a hill in high revs and a low gear I konked out which I researched AND CAME UP WITH A TOP END SEIZURE?
