New member! Thanks for the ad. Here's my issue... Got a 2012 yfm300gr according to the vin. Rebuilding the top end because the customer ran it dry on coolant and smoked the piston. Call me stupid but I've looked EVERYWHERE and can't find oversized pistons or top end kits at all for this bike. Just gasket sets. Not even namura... Which id rather not use. Rather weisco but... Can't find anything at all in ANY brand.Theres nothing listed for them aside the stock piston on yamaha parts. the piston and cylinder were only slightly scored I was about to Bore the jug no problem and can go with a 1mm over piston and rings but I can't find ANYTHING ANYWHERE. There HAS to be. Someone Help!!
