Hi.

I would like to adjust my shock but I don't really know what I am doing.

I carry pillions quite regularly and the centrestand will touch down and the back of the bike will spring up and down either before or after a bend (can't remember which).

I know it's not a sports bike and I don't expect too much from it. I just want to improve it a bit as I think the rear shock is set for someone lighter than me.

It would help if someone knew exactly what I need to do to change it for someone heavier?

thanks.

Hopefully in your tool kit there will be a large C spanner that can grip the top (or bottom depending on the shock) of the shock. Twist it so it compresses the spring* it should go up in clicks wack it up to near the top and if it is too much knock it down abit. Play about with it till you are happy. There aren't many levels of adjustment on this (Preload) maybe 8 or so, it's dead easy.


*Usually you can only twist it that way anyway then twisting it from the higiest setting will knock it to the lowest.

Hi

ZZR shock adjustment is a pair of collars on a threaded part of the body (one to adjust it, the other to lock it in place). The collars are at the top of the shock. It is a pig to get at and the Kawasaki manual tells you to remove the shock as the first step to adjusting it.

The range of adjustment is from spring free length -8mm to spring free length -17mm.

Probably well worth greasing all the linkages while the shock is out.

All the best

Keith

Sadly you need to change the shock/spring. You only have preload on the stock shock and although setting sag correctly will help, if you are a big lad AND carry a pillion, its not going to get you far. Your only proper solution is a new 'stiffer' shock with associated damping I am afraid Sad

Hi

There is a damping adjuster as well.

By the way, E model the preload range is from 15mm to 24mm.

All the best

Is there? I don't remember that on my old ZZR600D?? Perhaps there was ... but it doesn't change the fact that its going to be under-sprung whatever he fiddles with.

Stolen from a ZZR site:-

Front:

Preload (the blue thing you can see on the top of fork): 6 lines showing
Rebound: 1.5 turns softer than full stiff
Compression:two turns softer than full stiff
Fork tubes flush with top of triple clamp

Rear:

Preload: 9mm thread showing
Rebound: Full Stiff
Compression: 1.5 turns softer than full stiff

I'll just say that there is no single setup that works for everyone and sadly, if you are a big lad and take a pillion too, no amount of fiddling will sort you out, you are going to need a new rear shock to get it to work properly.

Deffo worth a tinker first though, you should at least be able to improve things a little, even if it is a fair ways off 'sorted'!! Smile

Shown in the ZZR600D workshop manual. Not in the E model manual, but is in the E model owners handbook.

Plus point being that it is barely any more work to change a spring on the ZZR than it is to adjust the spring that is there.

Manuals give it based on the difference between the spring length and the full uncompressed spring length, and it varies between D and E model (and quite possibly between different sub models)

All the best

Shocked But you need to actually take the shock out to change the spring surely, that isn't 'barely' any more work than getting a c-spanner out and adjusting in situ'?!??!?!?!!

Anyway, that aside, you of all people know it isn't as simple as just slinging a new spring on and chucking it all back together. He will have to get the damping adjusted/re-worked to suit/compensate, especially as we are probably going up a fair spring rate.

It might be worth ringing a suspension place to see how much it is to get the stock shock re-spring and valved, but chances are its more cost effective to buy an after-market shock that is of a higher rating???

Stuff all space to adjust the spring in situ. As mentioned the manual tells you to remove the shock as the first stage of adjusting it.

All the best
