'86 Fork seals...Who's are Best?

Postby Missourimike » Fri Sep 27, 2013 9:24 pm



The reason I'm asking this question, "who makes the best seals?" is because we just changed out the seals in my friend's '86 GL1200A for the SECOND time in as many weeks. First set installed by a motorcycle shop well known and known for good work. The seals lasted 3 days, very few miles. My friend and I thought maybe the fork oil was to blame, too much or too little, or the air pressure in the forks was too high. I made absolutely sure the correct amount(345cc ATF) was replaced in each fork and checked the air compressor for accuracy in front fork pressure. The new seals lasted about 5 miles. Both sets of seals were made by the same mfg company in Japan, both had the exact same seals, numbers, everything, just two different names on the packaging. These seals were said to be the same mfg as OEM Honda. NOT made in China. Fork tubes are not pitted, bent, or scratched. Bushings in the bottom are OK.
I've changed out seals in many bikes, GoldWings galore too, but never have had this happen to me before. Never have had seals fail on me. One thing that did concern me was the fact that the first set came out relatively easy, no tools needed. I have a fork seal removal tool, but didn't have to use it. The second set went in easy. Too easy, like they were not as tight as expected to be.
Anyone got similar experience or know what's going wrong here?

Well…. it's obvious that you're going to take both seal sets out again. And you are going to measure both seals to make sure they are i-dentical. You'll also make sure that both seals were installed right-side up. And you'll also measure the inside surface where the seal sets in the fork. I think you'll find the problem. Personally I've always been happy with OEM.
Good luck!!

Yesterday, made a 75 mile trip to my friend's home and looked at his forks and did some investigating on his problem. I took his word for it, that the seals were leaking. Yes there was ATF on the forks, when there shouldn't be. I lifted the dust covers off the lowers and looked inside. No ATF pooled on top of the seals or snap rings! They were dry, as they should be! Did find some ATF on top of the lower triple tree. I think it was coming from the O-rings that seal the air inlet area on the forks, just under the fork caps. I'm thinking the first set of seals were OK also, so the air seals will get attended to next.

I'm a big fan of K&L seals, caliper kits etc. I did my 1981 CBX forks back in 1997 and have ridden 45K miles since............they STILL are dry. I do change my fork oil every 4-5 years and when I did the seals I replaced bushings as well. I also very carefully check for rock chips in the chrome, and carefully stone them smooth. Well I just did my GL 1200A, I installed K&L seals, and PJ1 15W fork oil. I did have to "stone out" a few rock chips on these forks as well. I did leave the stock bushings in, they showed almost no signs of wear. Hopefully these will hold up well too.
Motorcycles:
'81 Honda CBX 1050 (current and forever)
'03 Honda RC 51 1000 (current and forever)
'75 CB 750 K3 (for sale) good running bike
'86 Honda Gold Wing Aspencade, (the Ratwing)
too many more to list..................

Those are just 4 o-rings and are easy to replace.

I used All BAlls a couple months back, and their still dry as a bone. One tube even had a scratch i was worried about, but it's fine, no leaks.
