You may want to use Honda SS-8 fork oil.

I used silkolean 20wt from the local dealer and my front end still was mushy. I put in 4lb of air and it helped. Haven't rode it enough for a good judgement. Good luck.

Honda recommends automatic transmission fluid. I have tried fork oil and the recommended ATF and the ATF gives you the best ride and control in my opinion.

Can you give me the actual type of ATF that you used? There are several different kinds out there, and my manual doesn't say. Thanks for your time.

yeh along with ATF and about 4 to 6 of air can give a pretty good ride in my humble opinion changing the TRAC system can also help a little

Put a set of Progressive Suspension's #11-1122 Fork springs in the tubes, use 15 wgt "fork oil", and you'll thank yourself. No air psi needed either.

Yes, what Crystal said!!!

You put the fork oil in the top cap of the fork tube. It is under pressure from the spring and great care must be taken when removing the caps. It can blast off and hurt you very bad. But if care is taken, and proper safety gear is worn, you will be good. Just keep your head and arms out of the way when removing the caps, and just know they are under pressure.

I thought that where I was suppose to add the oil Thanks pat, By the way did you find what type of atf to add? I am a newbe to the goldwing seen I might ask a couple of off the wall questions as I learn. I can turn a wrench on any thing just haven't had the pleasure of owning a bike till now children are all grown and I wanted one for a long time. Thanks again..

I use Maxima ATF Type F 10 Weight Viscosity.
Some people like it a bit stiffer and use 15 weight. Some like it a bit softer and go with 5w or even mix half 10w with half 5w which gives you a 7.5 weight. It all depends on personal preference and some to do with how much you weigh suited up. I weigh 220 pounds suited up and have progressive springs and the 10w works great for me. I also have the anti-dive system set at 2.

When doing a total fork oil replacement each fork gets 11 ounces of fluid. If you are just doing a change without totally pulling the fork tubes off and emptying them completely they take around 10.4 ounces. Your '86 may differ from my '87 but it will be close. I would do a search for your model year just to be sure.

Here is a link to the oil I used. http://www.maximausa.com/product/syn-atf/ On the drop down menu for viscosity option, I choose 10 weight. Around 10 bucks

Keep us posted with your progress and experiences with it please. Adding pictures makes people happy too.

Thanks for the insight .This bike is a work in progress the person I purchased it from I think he did a job for someone and they paid him some cash and the bike to do the job. I say this because he really didn't no to much about the bike. He told me the rear brake's didn't work and the front one's were spongy. I found out the rear caliper was in the trunk :lol: no wounder why the rears didn't work.I am finding little thing wrong with and getting it up to par. I will post some photos when I get a chance. thanks again
