I have a 124cc engine, says GPX on the Left Side Cover.

Any way to determine who actually manufactured this engine?



Numbers are- Model -1P52FM1 S/N 05A119288



Want to put a Cam in it and need to know which one to get?



Thanks,

Dave

I have a SDG pro mini 125. Where can I buy engine parts. Third gear went out.

It goes threw 1st gear and 2nd fine, but when I shift to third it feels like it goes to neutral. You can shift right out of it to fourth third is not there. Anyone who had similar problem, can you help me out.

I have been trying to figure that out myself. Apparently there are many mysteries with these motors lol I think they make the gearbox Z/XR/CRF50/70 style, and then put a KLX top end (jug/slug/head) on them, but I do not know for certain. Not sure what the difference is either, or if there is any sort of advantage. I have seen exhaust adapters for the klx head but they don't specify what they are for. I read a post that said klx heads use bigger valves, but what style makes more usable power I have read mixed opinions. Sucks being a noob lol

Okay my block tag reads 1p52fmh7c05698. Has 5 point stars engraved on each end. Tag says its a 110. Cylinder says 107cc and the piston says L 110. So is this a lifan? And it looks just like honda head. Anyone help me with what motor this is?
