While Bailey is probably right,my first option would be your trip to the SoF has sent it well out of tune,the very reason i use the Tiger for long distance stuff,i remember useing the S to go to Assen a few years ago after a good pasteing on the motorway from Calais it was well out of sync by the time we got to the Belgian boarder.

Pah.......lack of use is your problem mate...like trying to ride and old retired donkey in the Grand National
I always found my S loved being spanked.On one mad 600 mile midnight sortie I think i hardly managed to ride at less than 110.It purred like a kitten for next few days till i rode it round town for a while.
No really,Boxers just love to be used and abused rather than left to fester in ya posh shed with deep shag carpet.My old R100RT was exactly the same bless it(up there in the land of Motorworks bits).....wipes tear from corner of eye!

Well i have to say i've only had four beemers 3 to many!!! but found the complete opposite everyone went out of sync at a drop of a hat,A/B roads no problem a good pasteing on the motorway(110 Bailey how bloody slow is that!!) and it needed a good twinmaxing!!.

Bailey - What's this about? Is it really that crucial that the UJ's are lined up? Taking the swing arm off as well sounds like a right PIA. I have my replacement UJ, just waiting for some tools to arrive - new torque wrench etc.

Chris - I'd do the TB and valves if it was any worse but I think the motor is actually running sweeter... unfortunatley this is well hidden by the vibes.

That dear sir is twaddle;i'd call it something about nothing.
In all my years of 4 valve boxers i've never heard anything like it!And I'm quite pally with some BMW mechanics.
Bailey.

Thanking you kind sir I thought it might be the usual Pelican twaddle that can appear in amongst the more useful stuff.

When my UJ went I got a strange clicking when just pulling away as the slack was taken up. If you go on and off throttle you get a lot of shunt too - I would say that is the best indicator IMHO, or just gently turning the rear wheel by hand back and forth. If it's on the way out you'll feel some slack as you change direction. Mine never actually failed completely but was so noisy when I pushed it out the garage that I knew it was buggered. When I took it appart the UJ was just knackered with metal bits everywhere. I could rotate one end about 5-10 degrees without the other end moving at all. I've got a couple of spare UJs here but with over 123k on the bike I want to keep them just in case. BMW don't sell the bottom UJ seperately, only the completely shaft, for which they will well and truly 'shaft' you (sorry) for over £300 I think. I got a 2nd hand for £70 from motorworks and it's done about 60k so far

The slack or shunt is exactly what I've been experiencing in the drive - plenty of clutch in and start again moments to regain some semblence of smoothness in the ride.

I now have the 2nd hand UJ and the tools, just need the Loctite and Staburags or equivalent and I'm ready to roll / bodge ... TBH I'm failry confident this is a straight forward job... only the obituary will tell the truth

Adam

Hi Adam, as an aside, have you ever changed your exhaust mounting rubbers (where the cat locates to the frame) I change mine every 20k or so and it always makes a huge difference to vibes, especially in the 4k rpm region. I'm still on my original shaft at 85k.( that's not to say it isn't the shaft in your case)

Paul.

Hi Paul

Changed the CAT recently but not the rubbers as they seemed to be in near perfect condition... be nice if it was that simple.

If, as Bailey says, bumps etc might have an effect on the early demise of the UJ then I can pretty much pinpoint the day I did it, or at least started the thing on it's road to destruction.

Somersham to Chatteris road, accelerating towards the ton and hit three feck off bumps in succession that kicked me out of the seat and in the nads After that the paralever bearings failed and the vibes began.

Mileage wise, I guess the fen roads will kick the arse ouf a UJ faster than an M25 commute.

I know these roads well - he ain't joking either. Nasty with a capital ner.

Whilst searching for Loctite 2701 (270 is it's predecessor apparently) I came across this rear drive tech page - maybe there's something to this UJ phasing after all?

Anyway, can someone point me at a Loctite supplier, preferably online, but by phone if necessary.

Jason and Bob, I vaguely recall both of you found some - help please.

TIA

Adam

Adam - give these guys a call, they have never failed me yet.

Thanks Richard.

Oh Richard you are such a cad!
