I have always hated the way my clutch engaged at the far end of its travel. All the posts here I searched all have said there is no adjustment on these hydraulic clutches. A BMW mechanic also told me there is no adjustment. I have tried to get used to it, and over time, I have. However, I still did not like it.
I recently rode an 03 R1150GS, and the clutch was superb. It engaged at one third of its travel, just the way I like it. Now the master cylinder on the GS looks the same as mine, and it is also hydraulic. Why were they so different. I had a good look at the GS's master cylinder and mine and noticed a screw coated with red loctite between the grip and clutch lever. In the picture below, most of the loctite has been removed. On the GS, the screw was flush with the housing while on the GT, the screw seemed recessed.
So I decided to experiment, I broke the loctite seal and backed out the screw. Turns out it is some kind of actuator rod, and it's length has an effect on the clutch engagement point. Picture below shows the rod removed. I put it back in and adjusted it to be flush with the housing. Now my clutch engages about halfway, just the way I like it. Just make sure to put loctite back on the screw if you try this.
This rod is not shown as a separate part on RealOEM, I wonder why.
