I can resleeve your clutch master cylinder with inox sleeve, 105€, 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 140€. You will need to send me the old master cylinder and clutch lever with their bushings.. Alert : At the moment fellow riders outside EU will need to issue an invoice to me, and I will buy through Paypal the worn part, for a small amount of $12. The same amount should be declared as value at the post office. This way I will have a Paypal receipt for this amount and I can use these documents in my local customs office. This way everything will be legal, with no customs charges. 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 assembly bulletproof. So cost is 140€ for the upgrade. Cheers.
