Rear shock rebuild..any special tools needed? /project thred
Got everything together and tackled the tubes and seals tonight. It's really very easy other than cracking the thread lock seal on the bottom.
I drove the seals in by putting one of the old ones over top of the new one and working them down with a large screw driver and a hammer...
Here is a look at the tool. The nut that fits into the damper rod holder is 29mm.
In no particular order, here is the entire contents of a single fork leg
Et voila, new seals and no more leaks. Just waiting on a pair of shock sox and I can go riding. Cheers!

Helps to have a brother in instrumentation...the full suspension tune-up will make a huge different this summer

Thread revival..
Bufftester, regarding preload spacers you mention on page 3 for stiffening up the springs.
You said PVC, well my brother made some out of steel where he works by basically milling a tube out a solid piece of steel bar. Just wondering what length of preload felt just about right? The stock preload spacer is 11cm so I asked him to make a pair at 14cm to start with. After that if the suspension feels to stiff I can have him shave off a cm or two

Re: Rear shock rebuild..any special tools needed? /project t
Yeah, we used PVC because its cheap and easy to cut, but any spacer material will work. You might have him machine it at like 11mm and then machine up some 1 or 2mm washers for fine tuning. IIRC I used about 14mm to get the right sage, but that was back before I built my hybrid so it's all a little foggy

Thanks for the reply so I'm probably way off with going up 3 whole cm. No worries, I can just trim off a couple cm/mm for fine tuning. He also made them a bit thicker steel so they line up and match the cup on the underside of the cap. If yours were H conventionals, they are built a little differently with a rod through retaining the washer, spacer and top cap

4mm is what Race Tech is recommending now.

These are E conventional forks though, remember they're super soft. Where does racetech recommend 4mm. Is that somewhere on their website?

Re: Rear shock rebuild..any special tools needed? /project t
Yes. They are super soft. That is why you bought the correct rate springs for your weight, correct? Correct? We are not having a conversation about incorrect spring rates, correct? Correct?

If I had another $150 to blow on my kdx this summer I might consider it! But I think I already pretty much hit my budget cap with tires, chain, bars, piston etc ...
The idea by adding extra preload to the spring will boost the rebound a little bit

Re: Rear shock rebuild..any special tools needed? /project t
$150?? Keep an eye on eBay or post a WANTED ad on this site.
OEM 1995+ KDX springs do fit the 1986 - 1992 forks.
For the record, they DO NOT fit 1993 - 1994 KDX200 USD forks.

A set of stock H springs are .38s, so at least you'd be closer and they should be cheap.....in fact, somewhere on this forum a set of "parts forks" are going to another member, super cheap, and you might be able to weasel some springs out of them.Gotanubike wrote:Stock Fork Spring Rate: 0.298 kg/mm(stock)

Re: Rear shock rebuild..any special tools needed? /project t
I have used the Race Tech springs as well as the Eibach springs. Both are great.
If you are in a money pinch, perhaps you could find some used 1995+ springs. They are .35 Kg/mm instead of .30, like stock in 1989 - 1992. Heck, even 1986 - 1988 was stiffer than that. (.32 / .33)
At least you can see that you need a spring 40% stiffer than what you have. Those .30's are a joke. I still can't fathom the thinking on those.
6riders, they are .35.
Race Tech 3647 or Fredette Racing fork springs are the only springs I found to fit the 1993 - 1994 KDX200 forks. Stock 1995+ and Eibach 996 WILL NOT fit, as I have tested them myself.

.35...got it! I don't know what brand my spring are, the builder had them hiding in the "attic".....I just got lucky to get them....and for $100
OOH, I CAN tell you that they where sent from "Cannon Racecraft Inc." (Oklahoma).....Phone # (was) 405-524-7223.....try looking them up.....well, these were for the 94 forks.

That's helpful. 0.35 is a considerable step up from 0.298. I will keep my eye out for any good deals for stiffer springs in the future. Did not expect the blue USD springs to work but 95+ conventionals, because I recall reading they will work plus they are the same 43mm diameter tube
But I got the new preload spacers this morning. Brother dropped them off after his night shift...they are identical in every way but with 17mm of extra preload. I wanted to go between 15 and 20mm
Dropped them in and the result is a very nice improvement in rebound and responsiveness. No more stiction or getting hung up half way up on rebound...very happy with the result!
