Hey guys, I got a supposed XR650L JE piston with the above specs off eBay. The guy tells me XR's Only sent it to him for his XR650L. When I compare the part number on the JE website it shows it's actually for an XR600R. The piston JE has listed with the same specs for the XR650L has a different part number. Any ideas if I can use this piston or not in my XR650L?
