Hi Guys, I have and '84 G/S and have partly pulled down the engine (suspicious noise - seems to be timing chain). Whilst doing that it became clear I need the valve guides done (etc). The question is; Who can I get to do the heads (and maybe more, since the bike hasn't seen a real airhead mechanic in a very long time). The bike has been tortured by the shop in Hornsby that has BMW logos on it, and I have heard Motohansa are good but will charge really heavily, so who really knows these bikes and how do I get in touch with them? I am happy to wait. I am happy to ship/travel to the right guy, but obviously local would be better. I am near Manly in Sydney and love this bike. Thanks for your help.
