How do you deal with the heat that high power output always seems to come with? My mostly stock XR600 has heat issues with extended wide open runs. I start to get pinging on pump premium even though I'm only running the stock 9:1 compression. I've had to go to a 165 main jet to suppress it on a recent long distance high speed ride. So do you deal with it by only doing short durations of high power, or have you done other mods to help the engine dump excess heat? Those are some cool looking toys. It looks like a lot of fun. If you have the time drop us a note from time to time. I think that everyone here will be waiting.
