I just bought a 97 rm250 and I'm going to replace the piston (just waiting for the parts and service manual to arrive) I'v taken the carb off to check the float setting and to give it a clean up. Just wondering if anyone could give me an idea of what size the stock jets would have been. It's a Keihin pwk. Any help and advice on this and this bike in general would be great. thanks.
