When I got to AZ from BC back in October, I saw that my right fork (about 57.5K miles) was leaking
(small puddle on the garage floor), so I called the dealer, made an appointment, then removed the fork and took it in on the 24th.
I sat in their lounge reading while a new seal (aftermarket, NOT a Kawasaki seal) was installed, then returned home, installed the fork and went for a ride on some desert roads. When I hit the first MAJOR rut my fork(s) were ALMOST solid on compression - TOO much oil I thought, and when I got home could see that the fork was 'seeping' oil. Hopefully just as a result of the over-filled oil, NOT a bad seal, so I made another appointment. Took the fork into the shop on the 30th, along w/ my calipers and Service Manual to ensure that the fork would be filled correctly, which I did, along w/ their mechanic, at NO charge.
Now the forks action was correct, but over time I noticed seepage again. They said to bring it back "whenever" and they'd AGAIN replace the seal (at no charge to me), so on the 10th Dec I AGAIN removed the fork, took it in w/ my remaining aftermarket seal, and my calipers to measure the oil-level correctly. Got home, re-installed the fork, then some more riding....
DAMN - STILL leaking...!
Phoned, talked w/ the service manager who suggested that SOME bikes don't 'like' aftermarket seals, but bring it back when it was convenient and they'd change it to a Kawasaki seal, at no charge, AGAIN. Took it in on the 21st Jan, watched the 'tech' replace the seal again (but, HOPEFULLY better w/ the OEM seal), then back home to re-install it.
EUREKA!!! Finally my fork wasn't leaking - after about 3,500 miles, THREE seals, 1.5L of ATF, and FOUR removals from BIG RED...!
Went for a ride w/ a buddy from D2D 2015, lots of dirt, checked my forks....
NOW the LEFT one was seeping.
(I realized then that, at 60+K miles, I should have just done them both...), so made another appointment for an OEM seal for that fork, which was done on 05th Feb, and I just looked at both - NEITHER IS LEAKING!
ALL this is to suggest that when any of you need to replace your fork seals - go w/ the Kawasaki OEM ones! ADDITIONALLY - it was a good idea for me to monitor the level of the fork-oil, so it MIGHT be for you TOO....
