After messing with the jets in my carbs for the last month or so, i've finally got my bike running top notch...only thing is it's still running a little lean. I had to reduce my pilot air jet by 5, increase my pilot by 5 and my main by 5. I live at sea level. I haven't touched the air/fuel mixture screws yet, and i was wondering if they have a major effect on how the bike is performing? Would turning them out (they're on the front of my carbs) richen the mixture enough to bring me where i have to be without changing the performance too much? I'm really happy with how it runs now...i got major pull right through the rpm range, and would like to keep it where it is if possible.
