Cartridge Emulator adapter for 37mm Forks

[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.

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.

[Arronduke]

Put me down for a set also please, just purchased some new stunchings so while they are apart it would be good to fit them

Yes. The setup is exactly the same.

Why didn't I think of that... I must be really dumb!

I can for sure get a cartridge emulator set machined up for less than $100

The simple reason is that Racetech have an active patent on their cartridge emulators.
I am not sure how MIKESXS gets away with selling his emulator without getting dragged to court (they have successfully sued others).
His is slightly different in construction (it is built upside down compared to racetech's and is actually a better (and more costly to machine) version however in US patent law (this is different to patent law in lots of other countries including the UK) there is such a thing as substantially the same (i.e. even if something is slightly different in design/construction your patent is still valid if it does the same job in the same way).

It's called the Doctrine of equivalents - more info here if you want to read up on it. https://en.wikipedia.org/wiki/Doctrine_of_equivalents

I know a little bit about patent law. I also know I don't want to get sued.

Nobody has a patent on the adapter. I just developed it as a work around for myself.

It wouldn't be something you could get a patent on anyway. I didn't know that RT had sued people over their design but it doesn't surprise me.

can I have the cad drawing? I want to try and print a set. Material says it can withstand 12000 pst dynamic load conpression,

[salty_monk]

What material & type of printing are you thinking of? What kit are you using

What about creep and resistance to petroleum products?

[salty_monk]

Who wants to be a Guinea pig on the Nylon machined version? Save me pulling my forks apart....

needs to be someone willing to install quickly and put some decent mileage on them.

I should have a set to test about end of September.

To clarify these are the same design as the brass ones I have been using for years but made out of an engineering Nylon. Given the ABS pipe we use in our forks and the ramshackle ways I've seen other emulators modified I can't see why these won't work (and if they fail I can't see how it would be catastrophic failure as there is nowhere for them to go.

[Darin Jordan]

Dan,

Wondering if anything ever came of the new style emulator adapters you made?

[salty_monk]

Member on here has a Nylon set of adapters (voluteered as a guinea pig...) but no feedback yet. I suspect they will be fine. I do have a couple of other sets if you also want to volunteer...

To be honest there doesn't seem to be that much interest so I haven't given it much more effort.
