I was riding today and my bike was feeling a bit boggy, I though it was just that the bike was not warmed up yet. After about 5-10 minutes of cruising around the biek was still bogging out badly and smoking a ton. It was going just fine when i would pin it but it felt horrible 1/2-3/4 throttle. So when I get home i pull the carb apart. Everything looked fine until I came across the needle. The clip that was in the top position was now in the bottem position and the clip was REALLY bent. What could have caused this?? Also I am going to get a new needle and clip tomarrow and was wondering what is the best needle to get, it currently had a n3cj needle in it. 2002 yz250 168 main 45 pilot 5000-6000 feet 50-60 degrees 40:1 ratio THANKS!!
