Anti dive TRAC system

Post by Ravyn » Sat Apr 21, 2018 10:05 am



I have a 1994 gl1500se. I have been reading about a way to adjust the anti dive for different stiffness. can some one tell me how to do this. they are talking about settings 1,2,3,4. Looking at my anti dive units on the bottom of the forks I see no such settings. My front end is so stiff it's like a rigid frame. I am running NO air pressure in the forks. I do not know what fork oil the PO used but it is going to get changed. If the TRAC system is already set to 1, the softest it can get then I would like to disable the anti dive system as I have done on my gl1800 and if I remember right I disabled it on my 1993 aspy but fail to remember how I did it. Can someone please explain to me how to do this.

Thanks in advance.

Hi If you are running this with a sidecar. then the pervious owner may have stiffened up the suspension to allow for the chair..

Hi terry. Thanks for getting back to me. Yes this is with a CSC friendship 3. It was installed in 2010 and used very little. The complete rig has only 42,000 miles on it. It was set up by CSC and has the 6 degree raked tripple trees and 2 in. longer tubes. I have no idea what they used for springs. Which brings up another questions...... With the longer tubes does there need to be more oil in each tube ? It would seem to me if you use the measurement of inches of oil from the top of the tube down to the oil level then that would indicate more oil is needed ???? Also being 2 in. longer tubes means that there is more air to compress if you did not add more oil in the tubes.
However that front end is 100 percent to stiff and not acceptable. It needs to be much softer. And I just read that there is no adjustment on the 1500. That was on the 1200.
Gots any iders fer me...... :-)

You get a 2" extension piece with the rake kit as standard.
You may have to take the forks apart to see what's been done. they may have fitted a stiffer spring with a extension plug in the forks.
I put 1.1/2" plugs in mine just to raise the front a bit but I still have suspension

Hi terry. CSC installed new tubes that are 2 inches longer . No extension kit. I have the old front end that came with the bike when I bought it. Tripple trees, tubes, and sliders. So, yeah I may have to take it apart to see if the springs are the stock ones. I was mainly concerned about the oil level as I can't seem to find any one or any info on how much oil is needed with the 2 inch longer tubes, if any ??
I am changing fork oil now as I doubt it has been done since csc did the front end mod. he quit riding the bike long ago. He sold it to a guy in Mo. and I bought it from him. So I am the third owner. The second owner only had it for 2 months and sold it to me. His wife didn't like riding in the car. And he knew nothing about wings. They are Harley riders. He took it to a dealer in Mo. and had it checked over before I bought it. New tires and fluids and filters. Cost him a thousand dollars and he didn't charge any more for the bike. Nice guy.... :-)

Have you been back to the maker and ask them?
