Re: Installing YSS emulators on Curvy
 

You could install the emulators without modifying anything (more work I know) but then at least see the difference you get under braking. You should find noticeably less dive....

Re: Installing YSS emulators on Curvy
 

I did my pointy forks with the YSS emulators. They seated perfectly on the top of the damper rods. You do need to weld up the very small rebound holes and drill out the higher ones to be wider (10 / 11mm?) other wise the holes will be only allowing a certain amount of oil through and the compression setting on the emulators will have no effect as not enough oil is reaching them quick enough for them to take over controlling the oil flow for compression.


With the rebound hole sealed up you adjust your rebound by experimenting with oil weight. Then once you have that worked out you set the compression on the emulators with that weight oil . It's all a bit of a messy process and takes time but works in the end. I redid mine 3 times before being really happy with them.


I remember reading a thread a while back about someone who got something machined to adapt the top of the damper rods on a pointy to allow the YSS emulators to sit neatly. Sort of like a cup adaptor that sat inbetween the two.





+ If you think all the drilling and welding is wrong you don't need to replace the whole fork, just get different damper rods. I doubt you'll find that it is wrong though. Mine was a huge improvement.

Yep.

Re: Installing YSS emulators on Curvy
 

So frustrating, I read as much as I could on doing the emus and I'm a bit reticent about putting these ones in now . Will the O-ring give it stability? It's pretty much perching on the edge of the damper cup. Will it work? I don't want it slipping around inside the fork and fouling anything. I have to go to work tomorrow afternoon, so I'll probably put it back together sans emulators for the moment.

Re: Installing YSS emulators on Curvy
 

I'd get something machined. I wouldn't trust o-rings to keep it in place and you don't want it moving at all as it will either let all the oil past, or none at all and lock up your forks. I wouldn't enjoy riding a bike looking out for that happening all the time.

I fear that you're right Adam. Oh well, I needed to do the fork seals anyway.

Re: Installing YSS emulators on Curvy
 

New springs and heavier fork oil will improve things on their own too. Try it with the rest left stock?

Re: Installing YSS emulators on Curvy
 

The stock springs are rubbish so that is the best thing to change, but I found the (Racetech) emulators give the front a great deal more subtlety. Don't expect more stiffness, that's not the point, but things like tarmac ripples are dealt with much better.

Re: Installing YSS emulators on Curvy
 

I put in 10w oil and it felt lovely and firm, but the damping was horrible...any small bumps I could feel more acutely. I'm going to mix into 7.5w and see what it feels like. I don't want it to feel like a gixxer! lol

How have you set the preload of the centre spring on the emulator?
