[Another first liquid cooled bike question. My appologies} I have the radiator of my bike ready for repair. Putting it back on will be no drama, nor will filling and refitting tank etc.. However, I'm a little unsure of how to bleed the air out of the system when it's full. I can't run it with the filler cap off because the cap's under the fuel tank. It'll only be possible if I can find away to run the bike without petrol. :? Is it likely that the filler cap is so much vertically higher (nearly a foot) than the radiator in order to minimise bleeding requirements and running it for a few minutes with the cap off the overflow resivior will do the job, or should I be looking for bleeder screws somewhere? :?
