So I came across an 06 Kawasaki KX-6R I believe is what it is. Anywho, the motor is a 636cc. My question is, since it is still a 600 class motor, is it still competition legal? I know it is technically over the 600cc limit but some of the other ones are a little over as well. I need to know what to do with this amazing deal. Thanks to anyone who can offer up some advice!

You could de-stroke or de-bore it. Or put it on ebay. But a 636 cc motor is clearly not within the realm of 610 cc (or "the rules" as they are called). As such, you probably need to find a motor that fits.
