mushy front forks

Postby Mjholi67 » Mon Apr 13, 2015 10:49 am



I'm slowly working my way thru my 1979 gl1000. The front forks are mushy. What are the steps of determining what needs done? Is there a way to stiffen them, or do they need to be dismantled and resealed? I havent found a good source of information yet.

When you say mushy, do you mean they compress too easily? Too quickly? Too much dive when stopping?

It sounds like you could have either a) low/no fork oil, b) worn-out springs, or c) both. In any case, the forks are going to have to come apart to fix the issue.

Does anyone have a step by step for changing the fork seals on a 1979 honda gl1000. I have a printed manual but the visuals are poor.

Do the top of the forks on the GL1000 have air valves, and the bottom sections have drain bolts? - if so you might be able to drain and refill the forks if the seals are not leaking.

But it could well be a better process to bite the bullet - remove the forks and rebuild them - it is not an overly difficult project - and thereis a lot of self satisfaction in doing it as well. :D

I too have a similar problem? When I`m riding at 50mph my front forks bounce like crazy. They shim up and down the shaft about 2 inches {vibrate steady} and don`t know what`s going on? Any Help will be appreciated.

That indicates that there is no damping going on inside your forks - a very dangerous situation. Either the seals inside are completely gone, or you have no (or very low) fork oil in them. I would not ride your bike while it is in this condition, it's extremely dangerous.

Found the problem.....I had just changed my front tire and the guy from the shop did not balance the tire. I put another front wheel that I had on and the shimming was totally gone. But still going to do rebuild the front forks. How much is the right amount of fork fluid do I put in when rebuilding?

From Randakk's site:

Front Fork Fluid Capacity:

OEM Method:

• When merely draining and replacing fluid: put 5.8 – 6.1 oz in each fork tube (170 – 183 cc)

• When rebuilding (completely dry internals) use 6.6 – 6.9 oz in each fork tube (195 -205 cc)

Thanks for the reply Randakk . This will help me a lot when I do the rebuild.
