I replaced my OEM shocks with KONI's at about 25,000 miles in June '94, the OEM's were worn out !!!!
I now have 81,000 miles on the bike, and the KONI's still seem to be, doing a good job, I am tempted to disassemble them, even though there is no leakage, and replace seals and oil, just because.
I figure 15 years, and 56,000 miles, they may need some attention, and shocks go bad so slowly, that you might not notice it, until they are either rebuilt, or replaced.
Does anybody know of a place where I can get replacement seals for the KONI's ?
