But i think it's more easy and with less work for you if you remove the muffler and the header. You will have more access to work. For the throttle stop screw use an allen key.

You might want to consider this to minimize your frustrations.
Buy an ALJ (adjustable leak jet) and stiffer AP spring. I prefer the ones from Merge Racing. Once you have everything, pull your carb. Install the stop, ALJ, spring and any other jetting changes with the carb out and on a clean white towel on your bench. This way, you only have to deal with the difficult areas of the carb one time. Keep your fuel fresh (with Stabil in it) and clean, you may never have to pull the carb again, at least till you decide to mess with the engine.

Thanks again for all the information. I was able to change the throttle stop and take out the restriction plug. It sure does run much better. Fast enough for me now. I put about 60 miles on the bike and I am thinking I better change the oil soon. You guys are the best, and I'll try to submit some pics.
Yeah, on a new bike definitely change the oil and oil filter after 60 miles. Every 150-200 miles after that. Oil filter every other oil change. Once you get used to the current power, do the airbox mod, remove the exhaust baffle completely, disconnect the grey wire, and go up one size on the pilot & main jets. Be ready to be amazed by the power once again when you do that.

Really? I can't wait to ride it again. I might take off work on Thursday because the weather is suppose to be great. Another question if you still read, I know I'm still breaking my bike in, but it seems in 5th gear pretty much open throttle that my top speed was close to 60MPH. Dirt bike magazine claims 115MPH top speed. Anyone with info into the top speed of the WR 450F?
Your bike probably topped out @ 60 because it's still restricted. The magazine claim of 115mph is overly exaggerated, it's more around 90mph with stock gearing and the bike completely uncorked. It will also depend on terrain/traction. The speedo measures speed at the front wheel, it won't account for extra wheel spin at the back tire. Best way to test it out would be to find a LONG, straight, and CLEAR road where you can wind it out, but then we're getting into other "issues" by doing that. So I guess you can just take out word for it and be safe. I doubt the average person wants to go @ 90mph on a dirt road.
