Gold Valves for XL 350 Forks
« on: May 24, 2019, 06:11:58 AM »
I am in the process of building my XL 350 powered special

I want to use the 74 - 78 35mm XL fork , and adapt Yammy IT490 Dual Leading Shoe brakes to them.
 9
The bike will be setup as a supermoto really anyway and see probably 95% of its riding on the roads  , no supercross jumps to worry about for this guy..

I could use the IT forks, but I dont like the forward slung axle look, though I'd be open to suggestions for a fork-centric axle set of forks, especially if the're 38mm ~
 
Anyway, my question is  : are there any gold valve / cartridge emulators and / or progressive springs available for these?
There used to be a site that sold a kind of gold valve and you took the fork tube diameter and deducted 2mm and provided they had that size , it should fit, but I can't find it anymore.
 
Anyway warm regards all.

If you supply the measurements ( OD Damper rod or springs ) I can look up the right valve and choose springs to choose from .I stock hundreds  of different types of springs to choose from https://store.suspensionshop.org/    Just call or PM .
VMX shocks , We don't just sell them - I design and produce them individually for you since 1989.

I dont think you will find many if any dirt bike inline axle 38mm forks. I am not aware of any common ones. Some Kawasaki KZ road bikes use 38mm inline axle forks which are disc brake. 77-78 Suzuki TS250 are 35mm inline axle and so are 76 RM125. 76-78 TT500 and 76-79 XT500 are 36mm inline axle. i think there may be Marzocchi 38mm inline axle forks from late 70's to early 80's but they are most likely going to be road bike forks too.
Wanted - 1978 TS185 frame or frame&motor. Frame # TS1852-24007 up to TS1852-39022

Actually , I found 83 XT550K forks which are 38mm (which will suit the period look of the bike as the IT forks are just too long for it)  along with their triple clamps, I will be using them to mount an IT 490 wheel (yes, checked - same 15mm axle diameter) along with its dual leading shoe brake, also IT wheel for the rear. And I'm more than sure there are springs and cartridge emulators available for these forks or some that could be made to work..

There IS thinking involved in this process, mate - as well as  a lot of dumb luck. I must admit many things have just fell into place nicely, it's like it were meant to be...
 
Ciao for now.

And thanks YSS , I was actually intending on dealing with you.

I will need rear shocks so maybe you can help me find a suitable set for those.

But I will have to advise you on the fork internals measurements when she's apart..
It is intended to be ridden daily if need be, AND I will be showing and taking it vintage rallies and enduros

Talk Soon,

Tom.
