Few pics of bike. In search of the proper silencer. As well as a hi flite seat, baja light/or number plate, and front brake.

This ad shows the same tag that is on the mounting tab of the pipe.

Ive got this running now, supposedly had a new piston not long ago.

Problem is it doesnt rev up. It sounds like a rev limiter, no excessive smoke. At first i thought it was that blue magnum carb, but i swapped a pwk 38 on and same issue.

Either a cdi issue or wrong piston? I could make out the number 707650 through the plug hole.

What are the piston options for the 300 nowadays?

I am also looking for original 300 piston dimensions, and the lower flange thickness of the 300 cylinder, so i can tell if it has been machined or not, if anyone has those.

Ok, looks like the last guy tried to use a 76.5mm wiseco polaris atv piston. It comes up way short of TDC.

If anyone has original pistons specs it would be extremely helpful.
