    Did Some Suspension Upgrades Today

    Brought the Z into Rider's Choice in Mississauga, Ontario, Canada today to have some work done

    Ryan (Condor Racing) installed .90 kg/mm Race Tech springs in the front and changed the old fork oil with a heavier weight Motul oil (10w).

    He also installed a shock from an '04 ZX6RR which was re-valved and re-sprung with race tech stuff for a 180 lbs rider on the ZX6RR. We just stuffed it in the Z and he set the sag both front and rear and gave it a base setup for me.


    I didn't have a chance to go hooliganizing with it yet, but on braking it's like night and day and the rear doesn't keep remidning me of a bump a mile after I hit it.

    I think I'll be happy with these changes.

    Good price too.

    I picked up the shock from a buddy racer of mine for $100 (he said it was used one race weekend and then he put a Penske in and it's been sitting in a box).

    Riders Choice did parts and labour for $385 CAD after taxes.

    So $485 CAD all in for front and rear upgrades that are much better than stock. I'm happy.

    Cool! I have the same fork springs on order, so will be anxious to hear your further reports re the springs w/o the revalve.

    I also have a revalved shock coming from Motospecialties - Ican't wait!

    Not really... still need to figure out the settings and what the bike is doing.


    It's likely perfect for track, but over small irregularities (cracks, bumps, warps, etc) the rear end seems to be hopping all over the place.

    Gonna take some tinkering with the compression and rebound in the rear. I'm pretty sure the preload is set fine...

    We'll see.

    Alrighty...


    After much headache, I decided to put aside 3 hours lastnight and face off with my new suspension.


    Front:
    Stock Z1000 Forks
    w/ Race Tech .90 kg/mm Springs
    Preload Adjustment
    Rebound Damping Adjustment

    Rear:
    ZX6RR Shock
    w/ Race Tech Spring (for 180 lbs rider on a ZX6RR)
    Race Tech Valving
    Preload Adjustment
    Rebound Damping Adjustment (24 Clicks of range)
    Compression Damping Adjustment (22 Clicks of range)


    After taking it back from the Race shop that did the work, I immediately liked it under braking, but that was about it. I also somewhat liked it if I was tracking around a slightly bumpy ramp so long as I was hanging all the way off... if I was sitting on the bike, it was brutal and most general street riding and twisties was brutally bumpy and hippity hoppity.

    So lastnight I got the pen and paper out, picked a little 8 kms route, starting and ending at my driveway, with varying conditions and I recorded my setting, went for a ride, took notes and changed one thing at a time.

    It's finally dialed in to a rideable setting and I love it. Basically the biggest change from the middle-range setup the shop left me with, was that I turned the compression almost all the way out (out 21 clicks). The rebound is about in the middle of the range (out 12 clicks) and I have the front rebound turned out 1 full turn.

    I love it now, it tracks great, turns in nice and is still quite stable.

    Well worth it and WAY better than stock. I'm sure it could be better, I just need to spend more time on it and more time paying attention to what it's doing so I can tell the difference between too much compression and too much rebound.

    Did you start with proper sag and preload or did they set that right for you?

    They set the sag/oreload at approx. 30mm for me at the shop when we had enough people there to lift the bike and take measurements.

    I trust all of that is set up properly.

    I'm assuming the physical ride height hasn't changed since both shocks from eyelet to eyelet are the same length
