Hi folks, Well I wanted to report an inital success after doing the following mods this weekend: cut grey wire YZ throttle stop #168 main jet #48 pilot #100 pilot air OBELN clip position #4 1 turn out @<1000 ft How do you know of you need to adjust needle position, fuel screw or anything else? The bike started better and needed less choke. It idled a little better and pushed in choke sooner. Obviously the bike pulled much stronger and smoother from stock settings, it wheelied easier in both 1st and 2nd. Where do I go from here and what should I look for. I plan on getting a Vortip as I need to keep sound down and open the airbox when I get it. Thanks a ton.
