Unfortunately that's all I have myself is conjecture, but that's my latest thinking on how the problem should be attacked.arwadowd said:Well, I thought if anyone was compiling useful data instead of rumor and conjecture I might try to put my dead final in their hands. I do not imply any disagreement with your theory.
You want to chat with CharlieVT...aka Curtis. He is our in house FD expert. He has torn apart a number of them, rebuilt them, and analyzed them. He has even created a video showing how to measure pre-load.arwadowd said:Well, I thought if anyone was compiling useful data instead of rumor and conjecture I might try to put my dead final in their hands.

:histerica :histerica :histerica So, this would be your first BMW, then? :histerica :histerica :histericaniel_petersen said:Might BMW ever let us peak at their shaft dimension specs? It would certainly help.
Ken, I didn't know you spoke German.meese said:"There is no problem, there never was a problem, and therefore you must be riding the bike wrong. But if you dump that obsolete bike and upgrade to the latest-greatest new BMW, then this non-problem will be completely eliminated."
Until that one fails as well . . .
I wish it were as funny as it sounds. I've had 5 BMWs, four final drive failures, and four failed clutches (would have been five, but one bike was totaled before the slipping clutch got replaced).niel_petersen said:Funny!
I have three BMWs - after selling another two. :wave
Shaft dimension specs are classified under a need-to-know basis only. At home, there is a strict non-disclosure agreement between me and my wife.niel_petersen said:Might BMW ever let us peak at their shaft dimension specs? It would certainly help.
Maybe that's where the 4 (percent) number being thrown around came from. Somebody has to readup on what percent really means.meese said:I wish it were as funny as it sounds. I've had 5 BMWs, four final drive failures, and four failed clutches ............
If it is a drive off a GS I believe it is an "Evo" drive, not the same as the KLT final drive. Drive design is very different from the KLT final drive and failure mode very different.arwadowd said:The FD is from a 2005 R1200GS. It failed at 45000 miles.
Is there no centralized repository for this data? I understand that NP and David really know their stuff but again, I was hoping one of you wizards had a garage full of these things and reams of data that might someday be placed, thoughtfully and ever so gently, right up a certain blue and white roundel.
I'm not really that pissed. I still got a good deal on the bike.
