Agreed 600cc's should be sufficient. If a guy has a 700cc motor grandfather it in. As far as overbore? I just bought a 2014 Yamaha for $1500.00 off of EBAY and I bring it to you for 2mm oversize pistons, Am I going to pay you $500.00 and go racing?
Or will that 2mm come with a price tag close to that of another stock engine. Probably the demand for Kaw's is still pretty high too right?
