Rear shock question

Hi Folks, new to the forum although I’ve been a long time follower for info as I picked up a 1984 KDX200 last fall in need of almost everything for $125 haha. So I ended up rebuilding the motor with a plated cylinder and a newer kdx piston from prox. I also refinished all the plastics and have been redoing the electrics as the PO thrashed this thing with no lights and electrical tape covers on the original terminals. I got it with no carb and air filter but luckily the reeds were alright so I cleaned them up and checked that they seal, and fitted a pj34 carb and throttle cable I found for $40 on Kijiji in good condition. Now it runs but I haven’t done jetting yet so I can’t get it to idle? Also the back shock feels like a pogo stick, almost no damping, I figured the seals shot. Does anyone here know if I can rebuild the 1984 shock?
All help would be appreciated! Ripped this bike in the snow a quick lap and it’s a hoot
Also any info on the jetting and needle position would be amazing too if anyone knows

Welcome to kdxrider.net.
Congratulations on the '84 KDX200. The rear shock is rebuildable, assuming the inside of the shock body is not damaged.
You sound like you don't have the owner / service manual for your bike. Look on eBay for a used copy. They usually are pretty cheap and will be the best money you ever spend on the bike.

Thanks, I’m backpacking in Asia right now but I’ll be back in a week and thinking of rebuilding the shock for the spring. Originally I thought I’d just fix this bike and sell it as I’m a poor student. But already I’m feeling much more inclined to sell my two other projects if I can put the finishing touches on them. Hahaha funny how this little bike grew on me.
Also I’ll defin try and pick up a manual as these 83-85 models haven’t a ton of info available.
I’m kinda hoping for a pipe for it one day but it looks as though only dg makes one.

Congratulations on backpacking through Asia.
You have a KDX. You are "BIKE RICH".
On the shock, you will need a spanner pin wrench to get the cap off. I have not been into one, but know a touch on them.
The bottom bumper is the same. It uses a piston in the reservoir instead of a bladder.
It's the same seal head as the 1986 - 1988 KDX200. It won't have the "modern" piston and band like a 1989+ KDX.
Stay safe and have fun. Good luck on the rebuild.

Yes indeed I guess I am. I’ll probably order in a seal head then and give this a go when I’m home. I’ll also try to find the manual as I only found a partial PDF that covered the engine rebuild. Hopefully I open it up without too much surprise

One safety tip is SAFETY GLASSES.
Just in case it has ANY pressure in the reservoir, remove the nitrogen first.
