Front Fork "Bounce"

Postby reasonator » Thu Jul 21, 2011 12:50 pm



I have an '88 GL1500. When I get on the bike and stand it up, the front forks will "sink" some 3-4 inches. When riding (more so at slower speeds), the front end will "bounce" with the slightest bump in the road.

I'm wondering if buying a "GL1500 Factory Honda Fork Seal/Bushing Kit" and installing it, will cure the issue? Or am I looking at something else as a fix?

Any help you can give would be most appreciated!!

Mine will drop 2-3 inches, so I am curious what others have to say. No bounce on road and front tire is at 38 pounds air.

Does the whole front end bounce like the forks are stuck or just the wheel hopping about like bad shocks on a old caddy?
Stuck or sticking forks usually means it's time for new slides.
bouncing tire means no dampening,no oil.

I know what you mean about the bounce, mine does the same thing. I've only had it a month so I'm starting to get 'picky' LOL.
I plan on putting in a set of Progressive springs, replacing the seals and dust boots (oil as well obviously) and possably replacing the front pads while I've got the front end apart.
Anyone got any opinions on the All Balls seal/dust boot kit?......Mike

Seal / bushing kit will not help your problem. You probably have worn out fork springs. Progressive springs will more than likely solve the problem. While you are in there go ahead and replace the bushings and seals.

So check this out. I was ready all the articles I could find online and ran across one that mentioned that having the pincher bolts torqued too tight can cause a bounce in the forks! So, I loosened my pincher bolts and torqued them back down very carefully to specs in the manual....and....while it did not completely disapear, my bounce problem is all but gone now!!!!

The specs for my '88 GL1500 is 13-18 lbs. I took all 4 of the pinchers to 15 lbs and found the best results.

Anyway, thanks to everyone for their input, and I feel confident that the remaining bounce is simply AGE! I'm sure it can be fixed with a refurb on the forks.
