racetech emulators
 
having got the back end of my bike nicely sorted with a zx10r shock, I've just ordered myself a set of racetech cartidge emulators :-)

any gotcha's I should know about before fitting these babies?

I have a curvy with preload adjusters, hyperpro progressive springs & 15W oil in the front at the moment btw

maybee this is worth reading (from American SV forum) and especialy the part of the damper rod modification:

I did it the Zoran way and it feels very good en solid...

Buy some new copper crush washers for the damping rod bolts now, rather than finding out halfway through the job that you need them! :oops:

I thought emulators and progressive springs were a no no? Might be worth considering some linier springs?

Yes I think that's right.

From what I understand, progressive springs are used to try and overcome the short falls of damping rods. Emulators solve this problem, so linear springs should be used.

thanks for the replies & suggestions, I do have some linear '+10%' springs that the bike came with, I may put them back in. I may have to make up a new spacer tube though - anyone know where I can get the correct sized pipe?

the emulators turned up today - next day from pdq, so I'm suitably impressed with them (again). the installation seems to be fairly straightforward, but I'm not 100% clear what the preload adjuster controls - is this for compression or rebound damping?

I'll measure the tube when I get home for you. The preload (on emulator) is for compression. I have mine at 1.5 turns from the point where the slack is just taken up on the spring and 15w oil and I am happy with the results.

weazelz, the emulator preload spring controls the compression damping. The oil weight primarily controls the rebound damping, but will also have a lesser effect on the compression damping. I use 20w oil and 1.5 turns of emulator spring preload. I initially tried 15w oil and 2 turns of emulator spring preload but this resulted in too much imbalance between compression and rebound damping for me.

OD of tube is 32mm

weazelz 22-09-06 08:02 PM

right, I've done some measuring & here's what I've got:

* progressive springs & adjustable preload caps:

450mm spring (uncompressed)
60mm spacer
14-32mm adjustable cap (min-max)
2mm cap disk
---------
526-544mm total


* linear springs & non-adjustable preload caps:

328mm spring (uncompressed)
198mm spacer
1mm washer
0mm non-adjustable cap
---------
527mm total


does anyone know the length of standard springs & spacers?

what I want to do is give the progressives to my friend with an '00ish (no preload adjust) curvy & run the linears in mine with the racetechs & prelaod adjusters. can I make the required spacers from the existing spacers or do I need to source some 32mm tubing?
