modifying/tuning the rear shock

Anybody work on the rear shock, or get it modified? Installed a Race Tech Gold Valve kit or similar? Let a suspension shop deal with it? Were you happy with the results?

Replacing the shock with a better one seems like a safe bet, but getting the OEM shock dialed-in/upgraded might be cheaper...

I installed the emulators on my old bike a Ninja 500 with prehistoric suspension and it was a big improvement. I'm not sure how damping is done on the Versys though so am not sure they would even work.

The greatest improvement for the rear shock is had by switching to a spring with proper rate. Stock 900~940 lbs/in spring is too stiff to allow full use of available travel, no matter how you set preload or sag. At 210 lbs solo, an 800 lbs/in spring is perfect, even when charging through deep unforgiving sharp ruts and dips.

Yeah , for around $100 bucks I did the Yamaha R1 Shock transplant I love the plush soft stock R1 spring too...at 160 lbs. solo rider only...just drill out the eyelets...a couple washers and play with the adjustable hi and low speed compression and rebound...it's a fun project trying to find a 2008 shock but they are out there...cheap too...try it ,

How much do you guys weigh? Are you sure you're not at 2nd from lowest spring preload setting?

I've bottomed out at highest pre-load...but I weighed ~325lbs when I did that (currently 310 and dropping). So maybe the easiest way to tune the rear is beer and pizza. ;-)

I bought an R1 shock all done up, from a member here - LOVE it! (BTW, mine are from '07 to '08 R1s.)

So, I bought ANOTHER off Ebay for my '09 in Canada, and it's at RaceTech in California getting the same spring as the first one, but CUSTOM POWDERCOATING in brilliant yellow (my '09's green).

I HIGHLY recommend the R1 shock!

Is it documented in a thread somewhere what to do with the shock?

For example what needs to be machined, what bushings need to be purchased, are the length of the stock shock and this different and how to compensate, etc.??

Search "Fork Revalve" and you will get the associated threads. I also went the R1, Eibach spring route. Works good!

just take it off and get a suspension shop to do the gold valves if you ride in dirt a bit the comp damping will need to be boosted as it easy to bottom out in dirt over a few unexpected erosion mounds etc, that would be cheaper and easier mod to do rather than stuffing around with another brand shock

Thanks all.

The R1 shock swap seems more appealing since I read above that a heavier rider than me was OK with the stock spring. Can I have the same ride height with the R1 shock?

From looking at the R1 shocks on Ebay, it looks like it uses a linkage on the R1. It's a little surprising it would work so well in this application, but it sounds like there are a lot of satisfied customers.

Didn't find anything about rear shock revalve from searching fork revalve (or from searching shock revalve), but there was a lot of stuff about making a better fork shim stack, etc. Both ends of the bike need fixing, so that's good too.

If I don't go to a suspension shop for fork tuning, I might start a different thread for that--the suggestions I've found here are all for heavier riders.

I can use either an 07 or 08 R1 shock? But not earlier or later?

Was told the R1 shock was not serviceable. Apparently not.

When I installed the R1 shock onto my '08 I didn't measure its eye-to-eye length, but, when I raised the bike enough to remove the stocker the R1 shock fit right in. I'll measure the other when it comes back from RaceTech.

Several of the guys (read through that thread: http://www.kawasakiversys.com/forums...amaha+R1+shock) used other year shocks, but the '07 and '08 ones have ALL the adjustment screws on the outside, so accessibility is better, and I believe the '07/'08 shock looks BETTER!

Stlee - what exactly do you mean by ...not serviceable...?

In another thread I started (http://www.kawasakiversys.com/forums...ad.php?t=18069), I said that I used ATF to fill my forks, and that now the forks are "plusher" then before. Invader did some research and has concluded that my ATF has a viscosity around 7.7, which might be the reason...? BTW, I'm about 175# PLUS my riding gear (ATGATT!).
