I bought my bike used, and with all the stuff done. My bro in law just bought an '05 and we're learning how to jet his bike. Well, we decide to tear my carb down and see how it's jetted. Scott was having trouble getting the needle out, so he turned the throttle. Something happened and it was stuck WOT. My throttle stop had been cut WAAAAAY too short. Took us a while to figure out what happened, I couldn't explain it without looking at the book - but some black switch looking thing under the throttle cable cover had it's arm stuck in behind the throttle shaft making WOT. Anywho, I was looking in the book and it says the throttle plate should be about 3mm off the bottom of the throttle bore. I noticed my carb maybe was at 1mm. So we adjusted it so a 3mm allen wrench was a little loose. We got it all back together and it was revving up HUGE, felt like 1/4 - 1/3 throttle. So I started backing off the knob and it idled down. Soooo, &%$#@! is going on? Why is it running with just a tiny crack of air to breathe?
