Front fork seals for GL1100

Postby prc » Thu Jun 28, 2012 1:36 pm



Hi,

I am installing my new Progressive fork springs in my 82 1100 today.
The instructions that came with the springs recommends 15 or 20 weight oil.
15 weight seems reasonable but 20 seems too heavy.
Im not keen on putting in oil that is so heavy that it will blow a seal, the seals only have 500 miles on them.
Does anyone have experience with this?
Any help is welcome, thanks.

I used the 20 weight-works just fine.It is what progressive recomends.Remember to use less oil then honda reccomends.If the ride is to stiff-drain an ounce and try it again.Also,progressive springs dont require any air.You wont blow a seal using 20 weight-if you follow the instuctions provided.Regards,Johnyy

I went with 15 weight oil, I did put the factory recommeded amount of oil in because..well because my Clymer manual calls for that amount :o . The Progressive instructions didnt mention using less oil, at least I didnt see that. Thanks for the heads up, I will drain an ounce out if they are too stiff.
And thanks for mentioning that air is not needed, I was figuring the forks would now use less air pressure than before, but zero is even better, personally I would like to do away with those fork caps and that darned crossover tube. Got my hands full here, got the carbs out again to re clean them, now I have to try to set throttle/butterfly valves so it will at least idle correctly.
