Title: 2006 1200GS clutch slipping
Post by: PMH on September 03, 2019, 11:28:26 am
Hi there,

I'm sitting with a family members 1200GS and noticed a slight clutch slip when accelerating from low revs in say 4th gear from 90-120km/h.
Bike has 69'000km on the clock and barely seen any gravel in its life.

I'm not too familiar with the 1200's, and hoped to get some advice here.

Is there something to adjust? or is this an indication of the clutch wear limit reached?

Thank you  :thumleft:

Clutch replacement needed in the near future most probably.

Any traces of oil on the bottom of the motor and the gearbox?

Silly little thing, but I experienced this on a friend's bike.  Does the clutch lever release all the way, not impeded at all by the hand guards?

There might be. Why?

If there is oil, then the balancer shaft seal, output shaft seal or gearbox seals are leaking onto the clutch.  A split the bike and fit new clutch job.

At that mileage it is the only thing that could really cause it.  The clutch has hardly worked yet.

Nope she’s clean as anything.

Noticed one thing though: the rubber on the swingarm-gearbox connection popped off and was probably off for quite a while (including a verry wet Baviaans expedition). Should I do anything besides popping the rubber back on? (https://uploads.tapatalk-cdn.com/20190903/59a5de142e41885a182753973f1e7f4d.jpg)

You will only notice the oil at the junction between the gearbox and engine or below the engine.  Will post some pics tomorrow of what to look for and where to find it.   You will very seldom see any oil behind the rubber boot.

My balance shaft seal went at 50k so anything is possible.  Take a photo of the bottom of the motor so that we can see if there is a leak where the gearbox meets the motor .
