I had a 94 wr. It was a plug fouler so i put a YZ carb on it. I als had the head milled to change the squish angle as the thing had a definite PING to it. After those 2 mods they bike literally ripped. I was still pulling holeshots with it at MX tracks fully loaded with the woods gear through 1998. I did 1 top end in 4 years and rode the begeezus out of it. Enduros, MX, hare scrambles, you name it. Very durable machine.

My brothers 95 ate plugs also untill we rejetted and changed to the 97 ignition. My 97 didnt foul plugs. It did ping once in a while but so does my 02 YZ 250 on occasion. I mostly run 50/50 mix of pump and race gas in them.

Cool. It seems all the WR's used Mik Round Slides, and the YZ's used Flat slides. It's good to hear your ignition upgrade solved the problem. I will change this out first. If I change to a flat slide it will probably be a PWK.

Finally picked up the WR last weekend. NICE bike! I rode it back east despite the fact that the tires are nearly bald. She started right up, and after a test ride it was obvious that the thing was way rich on the pilot. I threw in a B7 to temporarily help the problem and it rode fine all weekend. I don't mind the tank size at all. It fits very similar to my 93 KDX, and I was quite suprised to see that it is smaller all the way around when compared to a 95-up KDX much less a 200-250 EXC. It's a bit touchy getting on the pipe I think mainly due to the rich pilot (IE slight 4stroking, then BAM!) As mentioned by you guys 1st gear is a bit tall for tight stuff, but it still preformed fairly well--I couldn't get this thing topped out in 5th even on the road. I had the same complaint when riding a 99 250exc. THis bike has real nice power...Smoothed out a bit it will be amazing. I think correct jetting, new tires, and different gearing is all this bike is going to need for me to be happy w/ it. In fact I think this might just be my favorite bike to date. Thanks for all your info!!!

BTW, this thing already has a Mikuni TM on it. I was glad to see it not equipped w/ the old round-slide type Mik. After looking at this carb I noticed it has what's called a "starter" jet. Can someone please provide some input as to which circuit this jet mainly affects? It looks like it's an idle-only type of jet, but how does this transition into the pilot? IE starter-->pilot-->main?

Thx...

How do you like your 03 KX? I hear they are supposed to be the poop in the woods as far as close-ratio bikes go!
