heres formula.. bore x bore (in inches), x .7854, x stroke (in inches) x 16.387
68mm=2.677 bore
61mm=2.401 stroke
it should run strong. Are you having it ported? If so it should easily beat a stock 400ex..

loose the fmf if you want maximum performance you need a right bend pipe i had my blaster worked so it would beat a 400ex stock np. get a dynoport if you go on ebay their $320 but so worth it
