Having recently bought my lovely 1100S, I then promptly buggered off to the USA on an unexpected work trip for 9 days. Got back on Friday, so took every available opportunity to get some riding in over the weekend. Yesterday in particular was great - had a good three hours hooning around and generally scuffing up the rear tyre!
However, one thing I've noticed is an occasional clunk when pulling away in first. Doesn't do it if I'm really careful. It's as though the transmission is taking up some slack, and everything kind of clonks in to place as you pull away.
Any ideas? Hoping it's normal!
Thanks,
Nik

Is a Face cam shock power transmission absorber an actual thing?! Sounds like a name for something that's been translated from German using Google Translate!Corvus wrote:Face cam shock power transmission absorber? Just doing its thang. Not suggesting it's faulty.
Do they knock? They look like they might!

Sometimes it's more noticeable than at other times with my bikes. Where are you in the South East? If we ever cross paths I'd happily swing by and let you compare it to another bike to put your mind at ease. I'm in London usually but often down near Farnham where the parents live.Motocod wrote: Good news, that's reasuring! It doesn't do it all the time, especially if I'm super-careful.

Dunno, but I had the right words but just in the wrong order! I meant face cam power transmission shock absorber. Every self respecting shaft driven bike should have one.Motocod wrote:Is a Face cam shock power transmission absorber an actual thing?!

Oh, and BSA A10's.
Regrettably I live off-shore (Isle of Wight), so not that ideal for meeting up!metropolis2k wrote:Sometimes it's more noticeable than at other times with my bikes. Where are you in the South East?

Thanks though!

related subject: Drive Shaft....I have'nt seen anywhere in BMW forums about having universal joints at 90 degrees to each other, to minimise the variations in velocity that occurs in UJ's (front drive cars use constant velocity joints for that reason). As a newbie to R1100S my questions are:
1. can the splines be assembled in various positions.
2. can the forward UJ be seen when assembling the rear one.
3. has anyone noticed any effect after reassembly.

Re: transmission
The shaft should be assembled 'in phase' so that the variations in velocity of the second joint theoretically cancel out those at the front joint.ODDWHEELS wrote:..................about having universal joints at 90 degrees to each other, to minimise the variations in velocity that occurs in UJ's

Doesn't apply to the R1200 range because their driveshafts are bonded!

Thanks Sandbar, you indicate that the splines can be assembled and not have the UJ's at 90 degrees, I wonder how many BM's are being ridden like that?
