Ok guys, I have a buddy who hit me up about a project 50 he bought. I have zero experience with KTM 50s and google has gotten me some info but I'm pretty invested now trying to get to the bottom of this. Its a 2003 KTM50 Frame. But when he opened it up it had an oversized piston. Measures the piston and now we are looking at a 60cc engine. He sent me some pictures and i was able to figure out that its a for sure modded 50 but no the issue is finding parts. So its a KTM 50, with a Gilardoni cylinder an PAX etched into the cylinder. I looked up the PAX website (modded engines) but their mod top end kit is out of stock. The big kicker is the Rod and Cylinder head have Beta logos on them. I'm more interested in the history now or if anyone has any experience with this platform.
