The grey wire mod is where you disconnect the grey wire from the CDI. This gives you more advanced timing and fuel curves.

The air box mod is where you cut out two holds on the right side of your air box. You'll see outlines of two ovals, cut there.

Mods to the exhaust. My bike came with the PMB tail pipe, but I also took the one of the baffles out of the muffler. From what I read, with the baffle removed and the PMB insert you are right at the 96db mark.

Also, on a WR the throttle stop is longer than the YZ so you are limited to like 3/4 throttle. Take it out and cut it, or go buy the YZ throttle stop.

You can also delete your AIS.
My bike is pretty fast after all that. I'm impressed.

Glad to hear people are still riding and buying the '05 WR. I've had mine almost three years and still giggle every time I ride it. I think about selling mine and getting a new one but all the mods I've done to mine I would probably end up doing to an '08 also despite the new frame and all. Sounds like you guys are headed in the right direction with the mods and all. I ride in southern Ca. and run a 170 main, 48 pilot and 68 starter jet. If you have a couple hundred bucks, I recommend the Power Now valve and Scary Fast Accelerator pump cover. No more hesitation on throttle response. Stick to the stock chain and sprockets. I ride and race alot and I'm still on the original drive system!

My next step is an aftermarket exhaust. I race alot of GP's on closed course tracks and lose alittle quickness out of the corners to the MX four strokes that I race against. I'm usually the only WR on the line, but the WR is more comfortable to me than a YZ.

Have fun on your new '05's!

I have a few other things I want to do to the bike. First I have my 13t front sprocket I'm going to install, then possibly a YZ exhaust cam. I think I want a stiffer suspension too. I don't think the WR is dialed in to my 210lbs body. Then later on, a stabilizer, after market handle bars, possible exhaust (if one falls in my lap cheap).

I am also 210 lbs. and have installed stiffer springs front and rear, but no revalving. I'm happy with it that way. Just six months ago, I switched to tall pro taper bars and GPR stabilizer, I'm also 6' 3". I couldn't believe I waited so long to get a stabilizer, but what a difference in ride comfort, control, and alot less arm pump.

Where do you get the springs?

Got mine at Race Tech. They have a web site with a chart of all the different spring rates that they offer.
