Hi guys I have a problem that I cant find the answer for. I'm rebuilding the top end on my 250x. The piston that came off of it was 76mm and has a wrist pin 20mm. The stock pin is supposed to be 17mm.

I cannot find a piston set online with a 20mm wrist pin.

I purchased the atv used and the guy said the engine was built in california. It is stroked and has had reverse removed.

Theres a number on top of the piston : 4543PS
XG

Not finding a piston for this thing is killing me.
