Thanks to Marthy for pioneering the ZX10R shock mod. Got mine installed yesterday (bitch to install, and set sag). Went for a ride today. Bike feels much better damped and firmer, front and rear are now working in unison. Temp was 40F, wet roads. sand in places. Not the time to hang it out, had a moderate pace going and felt confident. No more chassis pitching over bumps, or off/on throttle. Made the throttle snatch in "A" mode better just because the front didn't dive, and the rear didn't squat (at least very little compared to stock).
The rear is now 3/4 inch higher than stock, which is perfect for me as previously I had the front forks pulled up 1/2 inch in the triples to get more weight on the front end (forks are now back to stock height).
I'm 170.5 lbs. in my leathers. The 2009 ZX10R shock is maxed out for pre-load, to get me 33.70 MM of total sag. Although Marthy is around 20 lbs. heavier than I am, and say's it works for him as well, with the stock ZX spring rate.
I am currently using the same settings as Marthy: High Speed Compression 3 turns out, Low Sp. Comp. 3 turns out, and Rebound 2 turns out from full stiff. I'm sure these settings will change a bit when I am able to ride in anger.
With the front and rear mostly sorted, for less than $135.00, and the ECU re-flash soon to take care of the throttle snatch,remove the limiters, and timing retard, the FZ is transformed. This is the way the FZ should have come from the factory.
Thanks to the guys developing the FZ: Nick at Stoltec Moto, and those he is working with, and Marthy who built the first pipe for sale, and put the ZX10 shock on.
I feel now the FZ-09 is as good as my old Street Triple R's were suspension wise, and will soon be fueling wise, but with a lot more power.
It's an unbelievable bike for the money, especially with a few inexpensive mods.
