Ride- Progressive Brand Springs-GL1100, no air added?

Post by PhotoDoctor » Thu Nov 28, 2019 8:03 am



I have a 1983 GL1100 that I have brought back to life and put on the road. It is pretty nice survivor that had not been previously molested by uncaring wrenches.

Anyway, I put new fork seals in which I’ve done many times before and the left leg leaks fork oil only if I add air to the front end. The fork seals hold air pressure just fine, yet it pushes fluid up through the left seal. I’ve seen this before and usually pull the fork leg and put another seal in.

I’ve let all the air out and have put over 2 thousand miles on the bike now without a drip of fork oil coming out. I’ve also read somewhere that with “progressive brand” springs - air is not needed or in other words "the ride is good with no air pressure added to the forks".

So my specific question is – has anyone on this forum changed their GL1100 fork springs to Progressive brand Springs and find that they prefer not to add air to the forks?

Yes, I have. I installed a pair on my 86 1200 aspy. There is no need to put air into the tubes and the ride is excellent. If your looking to get away from having to put air into the front forks, progressive springs are the way to go. Best part is there is only one spring to install instead of 2 per fork.

Thanks for that info, it will be worth the 100 bucks not to pull the wheel, tubes, and so forth.

Cheers and Happy Thanksgiving!

Just be careful when your removing the tube caps. Keep your face away from them cause they WILL fly off if your not careful. I posted a "how-to" on how I removed the caps and springs on MY GL1200, but I can't find where I posted it LOL.

I've probably done 30 fork seals on old Honda's in the last 6 years ......... I only let a spring fly on the first one!

Also, it's a great idea to let the air pressure out before removing the drain screw on the lower leg : )

Cheers!

Letting the air out...yes, Draining the oil....no. If you lower the spring in slowly, what ever excess oil leaks out will come out from the top. No need to refill the oil unless you want to put new oil in it. Make sure you have some shop rags wrapped around the fork tube tops so the oil doesn't run down the forks and get all over the rotors and brake pads. I didn't refill mine and i've had no problems with it for 2000 or so miles.
