I am not sure if the YFZ has a rev limiter or not.. I bring this topic up because I was in Lucerne Valley, Ca. today and drag raced a cr250 on the dry lake and my bike felt like as if I was hitting the rev limiter while I was in 5th gear, pinned. This is my first ride since I installed the full HMF exhaust and 180 main and 48 pilot jets. I did another test run and it felt as if I was hitting a rev limiter in all gears while pinned. I did not make any adjustments to the needle because I didn't want to take the carb off during my rejetting, nor did I make any air screw adjustments. As far as who won the race, he did because my bike either hit the rev limiter and started sputtering or something else is wrong. Any help would be appreciated.
