Clutch slip?

[Kato]

Hi all,

I have noticed that when accelerating hard in higher gears and the revs reach about 5 1/2 thousand that the revs seem to jump up by about 1 thousand or so.

It feels and sounds to me like the clutch is slipping. Is this another bmw trait?

Cheers

Don't sound good how many miles has yours done,depending on (ab)use think there good for at least 60000 plus,just sold my 1st GS with 64K no problems at all unless you buy a newer toilet then expect probs at anytime according to what Iv read

Try it in high gear going up a hill under load you should get an idea if it's slipping or not.

Sounds to me like your clutch is slipping too.
It's not a particular trait of BMW's, just bikes with worn clutches.
Make sure it's nothing daft like clutch lever hanging up or clutch reservoir over-full.

I was told a good test is to accelerate from 4000 revs in lowish gear ie when torque comes in.

As said above, first check the clutch lever is not catching on the hand guard

As above and also check round the lower joint between engine and gearbox for oil.

Thanks for the replies. It is a 2009 and has covered 17k miles so far. I will check out the points raised then get it back to the dealer under warranty.

Thanks again.

I think you need to use a high gear so the clutch has a harder job and is more likley to slip

Clutch wont slip in the lower gears as the load isnt as big as when in the higher ones ie 5th and 6th. My last bike a GS 2010 with 22k on the clock, slipped in 5th and 6th above about 4.5k if the throttle was pinned fully open in an overtake or similar. But i chopped it in rather than repair.

Has anyone tried these folks

I had this on my 09 1200GSA, however, it was an intermittent problem.
My bike would be perfect for 1000's of miles, and then it would start slipping when accelerating hard in 5th and 6th gear one day.
But then it would be fine the next time i rode it....strange indeed.

I suppose that over the course of the 29k miles of ownership, the problems occurred less than six times.....and remains unexplained.

Mine does the same (2008 GSA), sometimes slips then ages pass and it doesn't.

It hasn't slipped at all in the past few thousand miles so I decided to leave it as it is £400+ just for the parts alone.

My rationale is that if my overtakes can't be aborted safely, I haven't planned them and therefore I shouldn't be overtaking anyway.

Same issue with mine, been slipping now and again for ages, 36k on the clock now, weird indeed. Might change it over this winter.

Intermittent slipping may be an issue with the master cylinder leaving the slave partially pressurised A strip and rebuild would be much cheaper than a clutch replacement.

It could also be the lever catching on the hand-guard.

Or perhaps not......

On my 2009 GSA the clutch started slipping at 36,000. After checking that the master cylinder oil level wasn't too high I stripped it and found the problem to be a very slight glaze, I dressed the friction surfaces and shortly afterwards chopped it in for my first KTM. I later found out that my old GSA had done a round the world trip with no issues whatsoever including the clutch. No idea what caused the glazing and my previous 1200 covered 50,000 miles with no clutch issues.

Got it booked in for the 17th of September for this and the rough running at low speeds. I will update you with the outcome.

I'm getting similar issues. Just had my first GS a 2005 with 65k on it. Bought it off my mate who never had any problems with the clutch, I picked it up on a test ride and have agreed to change it together. Has anyone tackled it ? New plates are available on line for under £90 so not going to give it to a dealer so they can rape my wallet.

You need to split the bike in two to do this job and its a fairly big one. You may or may not need more than the friction plate depending on what is worn. Unless time is a premium I wouldn't buy anything until you get it apart and know exactly what you need.

There are some writeups on here along with pictures so have a search.
