03 wr450f

I have a 03 wr450f. ITs runs pretty good, but there is some popping and backfiring and it runs pretty rich. Anyone have any fixes or ideas. Also I searched for stuff abut the throttle stop. I need to kno where it is on my bike, and how to preform the mod for it.

Check the Stickies at the top of the WR400/426/450F forum, lots of good info on mods. This link will help get you started with instructions and pics. It shows the throttle stop mod for a Wr250f, but is the same for your 450. Part number for the Throttle Stop is different though.

Good Luck :thumbsup:
