Evening all,
I've just joined ukgser and I'm looking forward to lots of fun and banter.
I'm also hoping that someone may be able to offer me some advice regarding a really worrying problem with my bike... please.
So I have a 2008 R1200GS with 28k miles. I bought it from a friend having previously owned a 650 GS. Prior to his ownership it was a BMW owned off-road skills bike so it's had a pretty hard life.
Anyway my biggest concern is a knocking, or clunking noise I get when the engine has warmed up. Whilst cold it's barely noticeable.
The noise I get is a metallic knocking noise and I can feel it below the bike through my footpegs as well as hear it.
When I twist the throttle whilst cruising in any gear it clunks then, almost as if it's picking up some slack, but it also does the same thing again when I roll off the throttle or decelerate and clunks again.
If I really try I can just about ride so gently that I can avoid it, but in normal 'every day' use that's virtually impossible.
I've had it checked by an independent BMW mechanic and he says there's nothing specific he can find wrong with it, and he puts it down to the bike having had a 'hard life'. I'm really not happy with that diagnosis though - as it's either right or wrong, and it can't be right the way it is!!
Surely there must be some way to pinpoint the problem.
He concluded that the only way the noise would go away is with a gearbox replacement which obviously means a helluva lot of money and labour.
Given the nature of the noise and how/when it happens, it would make more sense to me if it were a bearing in the shaft-drive or something similar, but then I'm not a qualified mechanic by any means.
The shaft drive did end up underwater at one point a few years ago, and because there's no drainage hole the water stayed in and caused damage so the whole shaft has since been replaced with a recon one from Motorworks.
If anyone here can help me, or shed any light it would be hugely appreciated.
Best wishes to all,
Mat.
