I just picked up a 99YZ400. I haven't had a bike in about 6 years so I'm pretty excited about it. I am also impressed at the wealth of info here on TT. So far, however, though I have searched, I can't seem to find anyone who has had my problem. I got a deal on the bike because it has a stripped pilot screw. The one that goes into the bottom of the carb right in front of the float bowl drain plug. It has tiny little threads and it goes in at an angle to the rest of the machining on the carb. Has anyone run into this?? What did you do about it?? Or does anyone have an extra carb laying around that they would like to sell cheap?? Any help would be greatly appreciated!
