Monty,
Is engine a piston port or a reed valve?

I just got pictures of it. Guy was describing as a free air, but its a fanner with the shrouds off. Single carb, Single exhaust, Kidney clutched piston port. So I would have to believe this is just another plain y433 motor. When he told me a free air 433 yamaha for only $25, I should have known I would be disapointed!
thanks for the help

Thanks, It was a real fun project. Didn't get much racing in though. Broke something every weekend!!!!!!
Last race I had a magnet explode in the flywheel at nearly 10,000 RPM!!!! Tore things up pretty bad

The GP motors usually had a dual carb setup, so you would probably be right that its a Y433.
