200x piston identification help.
Hey all, Im rebuilding a 200x I picked up few weeks ago. The previous owner said it smoked when he got it in a trade so he parked it and never really rode it. When i pulled apart the top end the cylinder looked really clean, possibly recently honed. The gaskets looked fairly new only issue was piston looked lil rough on the skirt but looked to have new rings. Only markings on the piston i could find were "PROX 011268" I've been trying to find some info on this piston to see if the cylinder has been bored over or anything as I dont have the correct measuring tool to tell but can't find anything.
If someone has any info on this item or a good source to find out it would be appreciated. The pro x site didnt tell me anything.
Thanks in advance.
