I agree with Malcolm, I can't imagine that Experience won't work on Airheads. Every now and then they sell Airhead GS's and seeing that they are pretty easy to work on there's really no reason why they shouldn't service them.. In a couple of weeks I will be getting my R80GS going again and do a service while I am at it. If you live near Balmoral you are welcome to join me and do your own service. I've got most tools for the job. There are only two valves per head, changing the oil is simple and bleeding the brakes no rocket science. It's actually fun, like most jobs that you don't have to do for a living :-).
