Cheap emulator alternatives

How do i work out the best rate for the spring then, and which oil as to 15 or 20?

Ive seen the damper rod mods so will be brazing the damper rod top hole and drillign the bottoms. Would it be worth getting a spare pair to do the mods on, and keeping the others should it ever go back to stock?
Anyone got a pair?

You can if you want, for price what is point going back to stock?
Note high VI of all treacle thick oils, what feels good this time of year will be sloppy in summer.

What do you weigh? Is it N or S? What shock on back?

Currently about 16 stone kitted up. Standard shock on rear but looking for a suitable to replace it with at some point.

Cool chart, only drawback I can see is head angle. For me a 12mm change in shock free length meant about 2 rings of preload on the front.

I would estimate .90 or .95, though that is a guess.

Here is same from traxxion

anyone fitted these yet?

So.....Did anyone take the plunge then?

I've bought some but Im not sure on my capabilities to fit them just yet

Anyone offering???

the set i ordered has just turned up today, overall pretty good bits of kit for the price. You certainly could not get a set machined for that price in the uk, however they will need a bit of fettling before fitting.

Already had them apart, some machining debris in one of them and some crap in the other, the machining doesn't look to bad but it's let down by the vast ammount of sharp edges everywhere, a few minutes with a neede file will fix that, i am also going to lap the important parts into each other for a better sealing surface. Only major issue is that one of the large silver washers is not flat, which at the moment will allow oil to bypass the spring loaded checkplate when the forks compress.

Also looks like the damper rods have to come out again, to have the small upper hole closed off and the lower holes opened up to 11mm.

should hopefully get them installed tomorrow, if i can get the upper hole in the damper rod closed off ok

I started fitting my bargain emulators last night, I needed to change one of the fork tubes due to pitting and leaking seals anyway. Others have gone for a top hat style bush to locate these on the pointy forks, but there is a slightly simpler design that can be used (it looks a bit scabby in this pic, this bush hasn't been cleaned and fitted yet)



I made these to be a press fit into the end of the damper tube, and made them slightly too long so the bush stood proud after pressing it in. Then I put the whole damper tube into the lathe and turned the bush down flush with the end of the damper rod.




The emulator then fits snugly into the bush:




In fact the bush could be simpler still, just a thin tube effectively but I was starting from a solid bar and I was getting fed up with producing swarf so I didn't bother turning out the entire inside diameter.
