I recently came across a yamaha 2 stroke cart. There is no key available. I have been trying to find information to identify this cart so I can get a new key and get started working on it. I read in this forum that there would be a serial number behind the rear bumper, but there is nothing. It is an older cart and i know it was running two years ago. If it would help identify this cart (and if I can figure out how to do it ) I will try to post some pictures.
