Guys, we all know you love your cheap, wanna-be OKO carbs. I used to be in the same boat. After using the POLINI carbs, I dropped 40 jet sizes, and run abour 30 degrees cooler, with next to no transition lag. These things rock. If you think your getting the best performance out of your carb that says "super happy product for racing", I just feel bad for you.
