Hello, my feather leg is oily on the underside and does not keep the air pressure any more. So probably defective. Have a GPX 600 R / ZX600C / year of construction 1996. Search now a new/used (if needed, then in perfect condition). Saublöde ask, since I had never had to do with it. How can I get out the dimensions of the spring leg? Or who knows it and can post it here? How do you extend the spring leg yourself or should you rather have it done in a workshop? Which feather legs do you have or can you recommend to me? Which addresses do you recommend to me? The price should be about 300 € maximum! Thanks already in advance. Micha
