I own a '78R100/7, since new and my current GSA1200'07. I can still ride my 355000 mile R100 anywhere on the planet, with all those miles and I've done so little to this engine. Its all original, valves too. 400w alt, i did put in a few years ago and a VW clutch plate way back when. My new GSA will not likely ever make that A+ grade in my book, however I love the new GSA and find it fascinating and its been good to 43000 so far, with a fuel problem(ethanol) eating the components in the tank. I find the GSA more comfy (all day rides)nowadays, as it gives me more leg stand up room. Its just to me, an older Airhead owner, I find it hard to believe BMW will ever equal their past machines longevity. They WERE Legends! Randy
Thanks for the great responses to date. Now a question on the first model year hexhead. What issues are showing up on the early (2005)1200 GSs?
