I haven't posted here in a long time but I have been lurking I'm just under 14k miles on an '04 R1150R and tore it down today to check the splines. I'm apparently one of the lucky ones and the tranny input shaft looked good. The clutch side showed a bit of wear but not enough, in my opinion, to change it out. I'm thinking I should up the interval for inspection as 9 year's is pushing it...doh!
You've probably gathered I'm not a rider.... Since the wife hates the bike, I just use it as a commuter for work :\
Hey Bruce, your right, the splines do not fully engage the clutch hub and your assessment of 5mm shy sounds pretty close. I think there was a company up in Canada that would custom make and input shaft that was longer as well but it was more than the clutch disk you mentioned. I think I read about it over at advrider some time ago. There are several youtube video's out there on this now too.
