Cartridge Emulator adapter for 37mm Forks

[salty_monk]

A few people have these fitted as a budget option to Racetechs. I have a set fitted using an adapter in the 83/1100 forks on my skunk. Work great and should work in all of the 37mm forks (GS1000, GS850, GS1100, newer GS750 etc). A few bodies in Canada also have them fitted.

I have the option to get some more of the adapters made up, want another set myself. Cheaper in bulk. Cost will be in the $35 range plus some postage. These ones will be made of an engineering Nylon (considering we use ABS pipe as a spacer in our forks Nylon will work fine).

Let me know if anyone is interested. I'll run a separate thread if/when I have them on hand, I just want to know if there is any forum demand. Racetech's are about $150 so it will be a decent saving. For me to do it I'll need commitment for a minimum of about 15. There is a volume of scale too.

I'd be in for a set of adapters. My fork springs are tired so a set of emulators coupled with a set of Sonic springs would be just what the doctor ordered. And this is the cheapest option for emulators I have seen.

Put me down for at least one set. If I install them and like them, I will go for two more.

I just wanted to make it clear that you'll need to buy the MikesXS emulators direct from them. Figure total cost of the upgrade will be in the region of $100.

For those that don't know - These allow you to split the two damping circuits on your fork - Rebound & Compression. You then adjust the rebound using oil weight & use the emulator to adjust compression damping to suit.

With the 83/1100 forks the rebound adjusters stay active after upgrade so you get a fork adjustable for preload, rebound & compression (without changing oil or spacers). You do need to disable anti-dive on the 83 forks.

I'll take one for sure Dan, possibly 2.

 

[Charlie G]

I'll take one.

 

[Grimly]

I'll take one, definitely.

If it wasn't for the exchange rate killing it, I would be wanting a set, too. As it sits, I can get an aluminum set machined up locally for almost exactly the same money...

Just to be clear, this is an adapter to make the XS emulators fit in the GS forks? I'm game to try a set.

Really? is this someone you know, or just as a shop price?

Are you printing the extra bits in nylon?

Not Printed parts these are precision CNC machined. I'd be somewhat worried about a printed part as the bottom does rest on the top of the damper rod. The only reason I am using Engineering Nylon instead of Brass or Aluminium is cost (and weight but not really concerned about that).

It is a buddy I know from the shooting range I used to belong to. He is a machinist and does work on the side at home on a couple of small machines.

Let me know when you want some cash Dan.

 

[salty_monk]

It'll probably take 6 weeks or so for me to get my hands on them once I press the "go" button.

 

[erickson_ron]

I am interested and also sent you a pm on the brake conversion.

Heads-up for those of us in Europe.
Heiden Tuning have the XS650 valves in stock for €53

There's also a very good instructional pdf on that page, which is dead handy for me as I'll get another set of these for my XS.

 

[limeex2]

Are the XS emulatators adjusted and set up the same way as Racetech? What I am asking, if I have someone set them up for me, would someone who is familiar with Racetech stuff be able to set these up also? If so,yes I will take a set.

 

[dantodd]

If you're going through the trouble of contacting a machine shop to make the adapters did you price having them machine the emulator? It sends that the price differential for an adapter plus the emulator would be more than just a properly sized emulator.

 

[Cipher]

Yes would that be a bad thing to do?
Get it specced out and send the cad drawing to China Inc.
