As the winter is now well and truly upon us and have some time before Spring arrives, quite fancy getting something done with the rear shock.

Can't afford to replace it with a nice Ohlins one. but would like to get it set-up properly and make it look better, nice new spring in yellow would be nice!!!

Any suggestions?

Hi,

I too am trying this due to the standard spring looking a bit rusted. I have seen them in Demon Tweeks for about £25 + £5ish to powder coat.

I phoned them today but they said I needed the spring rate and length etc. I have struggled like mad to find the rate which I now believe to be 10Kg/mm. However can't find the length. I will hav to get it off to measure. However, can I get the spring out of the shock myself (I know it could be dangerous and to use compression tools etc) or is it a specialist job. Demon Tweeks say they will fit it (Ride in Ride Out) for an extra £60ish.

Any advice? Do it myself or pay to get it done by someone who knows? Either way, I still need to know the length to make sure they have it.

Have spoken to Maxton, they sent the following information regarding both the front and rear units:-

Kawasaki ZX-636R 2003

Front

The forks have a lot compression damping, especially when they move over a small distance - e.g small bumps on the road. This shows itself by giving a very harsh and twitchy ride at the front, that can be uncomfortable on the wrists. It is not a spring rate problem and just changing the springs will not cure the problem, the springs are actually a bit on the soft side. The other problem is the forks spring back at you when you let go of the brake this is because there is not enough rebound damping. This makes the more difficult than it should be to turn in to a corner and can cause the bike to run wide out of a corner. We revalve and respring the forks reducing the compression damping and increasing the rebound damping so the bike is a lot more compliant and holds a line a lot better out of corners, we also fit harder sprigs to suit the riders weight and what they use the bike for. The conversion costs £250.00 plus Seals £20.00 a pair and Bushes £10.00 each if needed. ALL PRICES EXCLUDE V.A.T.



--------------------------------------------------------------------------------
Rear

Like the front forks the standard rear unit is very hard and harsh, this makes the whole ride of the bike very "wooden" and uncomfortable. The unit has a lot of rebound and compression damping inside it and also has a stiff spring for the average rider weight. We do not revalve the unit and respringing it would not soften the ride, as the damping would then overide the spring. We recommend a replacement unit, we supply our own Maxton unit, its fully adjustable via a shim stack system and has an spring measured to suit your riders weight and for what purpose the bike is used for. There are two types of unit the standard unit which costs £405.00 + V.A.T and the remote reservoir unit with a second compression adjuster that costs £490.00 + V.A.T. Which unit you need depends on how fast your riding the bike.


So, not much different to the Ohlinds unit in terms of price......plus the Ohlins unit looks great......

Pity, for my J1 model I got it all done for less than £600 and it was well worth it (prices included them stripping and rebuilding the full bike). With the Ohlins kit you'll need to set it all up yourself.
