Well, got my carb tune pro in and did it today for the first time. Followed the instructions listed in the thread on here and it was a breeze other than locating the adjustment screws. 1 & 2 were synched as well as 3 & 4, but 3 & 4 were out of synch with 1 & 2. Got it all adjusted and man, this bike is quick. Really hoping that the mileage improves as that was the main motivation for wanting to tune them. Last time I checked, I was getting right around 30 mpg. We'll see. Thanks for all the great info located here.
