As already said!
Problem with break handle, sinking to stop in 5 sec at slow brake! Hard break, rock steady.
Where to get a repair kit or a handle at a decent price?

Problem solwed by my 67 year old mc-guru.
Demounted, cleaned with methylated spirits, greesed with the right silicone grease, mounted a new circlip instead of the missing, and remounted with new dot-4.

Fully functional now!

Now waiting for the accelerator http://www.sol2.be/Accelerator/English/Features/index.html to the hp2 (with de-cat headers), which worked as a dream on my 1200GS -10.
Also waiting for the Adventure pedals to be used on the GS.
