after reading through several post I noticed that most of you guys have shorten the throttle stop screw or replaced it with one from a yzf. I had the dealer do yz timing while doing some other work and they removed the throttle stop screw. I have heard that without the screw the bike will run poorly at wot, I have not noticed it but, I have not ridden with one in place. Do I need a throttle stop screw????
