Pretty trick, but so is the price.
I like your 1998 better than this one.....

Spent a lot on mods.
I need to get my shock worked on, the damping adjustment doesn't change.

Update on the 220
checked swingarm and shock linkage bearings, all look new(re-greased); installed new tires and checked wheel brgs. The PO drained tank and carb 7yrs ago when last used, both were clean. Sprockets look orig and almost new, a little rust on the chain. I’ll be changing fork oil, engine and coolant. Replaced all radiator hoses.
It’s apparent the bike was never disassembled, correct bolts all in the place, most have the factory lock-tite.
I think the tires may be the originals.
Yay2

Only issues are crack on the gas tank near the filler and rear shock rebound dampening doesn’t change turning the adjustment screw.
I’ll try plastic epoxy on the tank first, I have a rebuilt shock to replace the one in question

The KDX220 is done, sporting new FMF exhaust system, still goofing with the jetting. It will make it debut at Cal Dreamin.

Because California dreaming was canceled I decided to take the summer off and take a look at the piston. The KDX 220 has a problem with breaking pistons and I wanted to take a look. The piston was OK but the cylinder lining was coming off. I sent the cylinder to millennium technologies to have it re-plated. Also I had the machine shop shave off the cylinder head to get the squish area lower. It’s now at about .038”.

I bought a Keihin PWK 35mm Air Striker Carb for my KDX220 to replace the standard PWK 33mm carb. Suppose to get give a little more top end and not really lose bottom end. Plus cures the jetting issues, basically from 1/8-1/4 throttle. By all accounts it's the hot ticket on the KDX-rider forum. The other way to go is RB Designs, but that route was more, and you still had to buy a new carb.

I hope you are only going to motorcycle race with that carb on it.

I had to go check my garage... looks just like the one I got for my Ninja 150RR... :)

Haven't tried mine yet, racers in Indonesia say it's the hot tip for the little 150.

I had a 96 KDX200. Only year they came with purple tank and shrouds. I swapped them out for an IMS tank and shrouds. Bike had the full Fredette racing mods and I won a B200 enduro championship on it.
