Will these or any other for 37mm forks fit on a 1978 gs1000? Would go on stock forks modded with sonic springs, racetech gold valves and PVC spacers.

I had a set of GS1000G forks here with OE preload adjusters, I thought those would be nice in our racebike's GS1000E forks - both 37mm stanchions - but they were a different size thread...
The only 37mm stanchions those are guaranteed to fit are GS500....

[Darkspeed]

Yeah its a guessing game. The way it looks there are a lot more variables than I thought to fitting a set up than just "37mm".

Why do you feel you need easily-adjustable preload?

Yeah, it might take about an hour or so when you put the forks together to dial them in, but after that, isn't it pretty much "leave them alone"?

Preload just adjusts your ride height. Changing the length of a spacer tube when assembling the forks will do the same thing. If you happen to not get the height correct, you do have to open up the top of the fork and change the spacer, but as mentioned, it's a one-time effort.

Preload does a whole lot more than just that. It alters characteristics of how the forks work under cornering, acceleration and under braking.

My fork caps are junk(clear coat flaking, deep gouges from channel lock teeth, leaking air valve and missing valve cap. I could just do OEM but this is a chance to add the ability to tune as well. Yes it may be overkill for a vintage bike, but it will be riden in a spirited way and I like the abilities to tweak after baseline sag to get the bike handling the way I want it to.

GSX1100S Katana fork tops fit, they have preload adjusters. hard to get hold of though

[Darkspeed]

Thanks. I'll see if I can track down a pair...not offered from suzuki nos parts I take it.

You don't need air if you have the correctly rated fork springs and fork oil.

Thank you. Will order a set and post back

Fork preload adjusters really don't do much for you. They are used only to set sag (or should be, anyway), and that is generally a one time job. Unless the load on your front end changes dramatically (maybe you put a Vetter Windjammer on in the winter?) it's just not something you mess with.

The 83 1100E ones DO NOT fit the earlier 37mm forks just in case that's of use... (you can however fit the whole fork leg)

[Big Rich]

Darkspeed, I had something similar on my GS500 forks..... and they leaked fork oil. Still have them somewhere out in the garage - if you want to pay shipping they're yours.
