Bugger, slipped in before me I see Mr Taylor!

I'm not quite sure if I have the right idea here, does the emulator move in relation to the top of the forks once installed, if it does my plan is foiled..

Not quite right I'm afraid, it sits atop the original (modified) damper rod.
I trust you meant it replaces the function of the damper rod, rather than the damper rod itself?

yup gotcha, I've been reading everything I can find about suspension lately (have a looky at my blog to see why), the suspension tech threads on here have been a big help so far..Bear in mind that to be totally effective you will ideally need to get the correct weight fork springs for your weight/riding style
Suspension tuning is the best bang for buck mod you can make to a bike in my book!
I don't know how relevant it is at this stage but I found a spring weight calculator that tells me .75kg/mm springs would be about right for the weight of my scoot when assembled..

I guess it depends on your viewpoint but as the fork tube is fixed in the triple clamps I would describe it as moving with the staunchion (or fork lower). The emulators position is where the red blob is in the attached pic.

That sounds very light, how much do you weigh in Kg's without your riding gear? And what sort of riding are you doing? (e.g. commuting plus a bit of open road riding moderate to higher speeds etc.)

About 80-85kg with my gear (a guess), bike should be around 150-160kg when its done, tank holds only 12L..
The intention is to put it on the track..

Using Race Tech's spring rate calculator and using the bike as a early model VTR250 (as they don't list your particular bike) they recommend 0.85kg/mm springs which is closer to what I thought they would require. Admittedly the early VTR has smaller diameter forks than yours but the bike weight is similar and the dynamics would be similar.
Robert could obviously advise you more accurately (probably worth a PM if he doesn't poke his nose back into this thread) but I would think that is closer to your desired spring rate bearing the intended useage in mind.
There are also other factors like the spring preload and spring weight (they are changeable) on the emulators as well as fork oil level which will also have an effect on the final set up.
Of course then the next thing is the rear end.....

Also, dont be tempted to buy those dodgy Thai copies as you will end up horribly dissappointed. The poppet springs sack out, the low speed flow modulation is all wrong and sloppy and the material is alloy with only a veneer of anodising, so the spring rubbing is going to wear them out fast and send chards of alloy through the forks. The Race Tech emulators are a well proven and reliable piece of kit and we have different settings for road race application.

Rightio, I just got a spring out, measures in at 30mm, the windings aren't all the same, that means its a progressive rate spring yes ?
Forum whore
progressive yep! a linear spring might be a good upgrade [weight matched] while your doin the gold valves.

Yeah man thats what I was thinking, I've read over and over from people who are knowledgable on suspension and noone rates them too highly eh..
Haa as such I forsee myself being poor for a long time..
Unexpected Spanish inquisition
Poor...but happy!

Can't put a price on happiness eh..
