I can resleeve your clutch master cylinder with inox sleeve, 100€, post costs included + 35€ for the KTM 10.5mm spare piston # 50302032000 (you could buy that yourselves) 4 tiny bearings are also installed in the lever joints, to compensate for lateral forces Total cost 135€. You will need to send me the old master cylinder and clutch lever with their bushings.. Alert: You need to declare low value to the post office, lower than $28 in order to avoid customs charges, if outside E.U.. Cheers. P.S. In the following pictures there is an aftermarket lever I bought. Unfortunately it lacked the necessary extrusion to operate the clutch safety switch, so I had to fabricate it with some glue. I bought this when my original lever developed lateral play. When I realized where my original lever was worn I installed some bearings similar to the one you can see on this spare one and put it back in operation (140k kms). This little cylindrical part is holding the red adjuster. It is machined to fit with the 2 bearings. It is shown in the next picture mounted on the lever. Two bearings are mounted on the lever joint with the red adjuster I install ball bearings same to all places. Makes the assy bulletproof. So cost is 135€ for the upgrade. Cheers.
