This is to say that I found the parts in Beijing and want to let everybody know that the person there was very helpful and straight down the line. He send me the parts sheets, I marked what I needed, he gave me a quote, I paid by paypal and three (3!!) days later the stuff arrived in Sydney. 10 out of 10. Definitely recommended.

Also thanks to the two expats in China who offered their help in sourcing the parts. The spirit of motorcycling is still well and truly alive!
Happy & safe riding, Roland
