Race Tech Emulator on KZ750 - What Oil?

[Nessism]

As I understand it the emulators only affect compression damping.

Instructions call for 15W oil but the Kawasaki manual says 10W for the 750 forks.

If I go with 15W the rebound damping will be higher right?

If I go with 10W the compression damping will be lower, so maybe I should crank up the emulator a little?

Help appreciated, I'm confused.

I have not (yet) had the "pleasure" of tuning emulators, but I would suspect that since Kawasaki did not install emulators, their oil suggestion is for their stock forks. I would follow the suggestion of the emulator manufacturer. I have no personal experience (yet) to draw from, so will be watching this thread.

It's kind of a trial and error thing. You have the basic concept, just a matter of tuning. I've only gotten it right on the first try once, that was on my old 650G. Can't remember which oil I used, sorry. I thought RaceTech suggested 30W with the emulators? I might have used that....


My 550/675 is on the harsh side, I need to change it up a bit. Think I'll start with loosening the screw and see what happens.

So again, the emulator only affects compression damping, the regular fork damper rods control rebound damping.

Since the stock forks spec 10W oil that means if I go with 15W per Race Tech then the rebound damping will be greater than stock. That's what I'm concern with. I'm not sure if more rebound damping is good.
