G'day Peter

As my introduction in the Intro forum suggests, I'm into the original 1985/86/87 GSXR's. I'm rebuilding the forks on one at the moment for a drag bike project. The bike will not be road ridden. While the bike will be pretty much street trim with only minor modifications to reduce weight, I would like the front end reasonably stiff so I can lower it on the triple clamps as much as possible.

I just ordered a new set of Progressive Springs for the front and have fitted some custom made alloy blank off plates where the Suzuki NEAS damper use to mount. I bought the blank off plates from Bike Bandit.com i believe.

I guess my question is the best way to further stiffen the front. Extra fork oil, spacers on top of the springs, any other advice would be appreciated.

Cheers.

For the drag bike I have been shortening the forks, but leaving the fork some what compliant for traction. Cancel the order on the progressive springs, they wont help you. Call me for more details, I type slow!

We don't cut anything. We shorten the fork by limiting the travel. Going back to stock is easy, we remove the droop limiter and make a longer preload spacer. that's why I said to call.

just dont ask him how to go faster. he has a pre recorded answer.

"youre riding a ______ just twist the fucking throttle and hold on...if it tries to do something other than that just tell it NO and force it to do what you want"

Well I guess we know who wears the pants in your race program.....

Peter im in Australia, not an easy place to call from. lol

I had to purchase new fork springs anyway, the springs I pulled out apear to be the wrong ones. The Suzuki manual list the service limit on original springs as 459mm(18.1 in) however the set sitting on my office floor at the moment would be lucky to reach 330mm. Obviously a home job done wrong.

Any further expansion on what you mean by "remove the droop limiter and make a longer preload spacer" would be appreciated.

The droop limiter goes over the damper rod and against the top out spring. It limits how far the fork can extend. The preload tube needs to be shortened to maintain proper preload as well.

Or ask "how do I make my bike (non late model / Jap-Italian) handle better for the track?"
PG - "track? - your bike doesn't belong at the track!"
