Equalizing fork pressure w/Goki fitting?

[Suzukfan78]

I was looking at an old article about the wes cooley superbike gs1000 and it shows and talks about a little fitting that connects the fork tubes at the top to equalize fork air pressure; they called it a Goki fitting or somthing...Is there a way to make somthing up with two fittings that screw in and use a tube or pipe connecting both fork tops to one schrader valve? Or can you buy these? I already know progressive springs help so much you dont need air...but if this is easy Ill try it. Im really tired of trying to always get them equal and I dont have the special suzuki tool that came with the bike.

don't waste your time, just install progressive springs and new fork oil. and don't presurize the the forks with air. and you will be very happy


the reason they used air back in the day was because it was the only way of adding preload in a snap, modern bikes just skrew the springs down now and don't mess around with using air.

do what i said above get it dialed in and you will be very happy, you are not going to need to keep adjusting the preload of the front of the bike very offten if ever once you get dialed in.

if you wanted to get tricky get a set of old caps drill a hole down the center, tap it, run a allen skrew through the hole and sandwich a thick washer between the 2 nuts. Now you just made your self a preload adjuster to compress the spring. skrew down the allen skrew till you get the sag you want and make sure the other side measures the same.

>> Yes see Ryan's answer, not worth the effort

>> use a heavier weight fork oil, I use 20 weight in my 1000S, NO AIR.

My 83' 1100E has air and the boots and line to equalize the front forks. When I took it off and covered the holes in the fork tubes my death shake went away above 100mph. the only difference other than that is that I use 15w40 oil in there now. By thickening the oil a bit it helps to slow the action a little. Effectively adding a bit of fake preload.

Our front forks are completely different. i just mention this to demonstrate that air pressure isnt needed. They only recommend 7lbs anyway. Hardly worth it and it always burps out on fast stops and big bumps.

The cooley bike was a repli racer and racing machines check everything all the time. pain in the arse daily.

Progressives and thicker oil is about all you've got for choices in upgrades unless maybe you can see if Race Tech makes a cartridge emulator that will fit your forks.

A word of warning on this move though. YOU need to know the inner measurements to tell them. They have no clue.

Increasing oil weight increase both compression & rebound damping. This means for any given force the fork will compress slower, that's the effect you are seeing & it is somewhat like adding more preload to the spring to a degree...
