I just called my local Dealer and he advised me to adjust the air screw on the carborator bowl to get rid of the sluggishness off the line. Told me that the EPA forces them to adjust the screw very lean. He said that its located in the front of the carborator and that adjusting it will greatly increase the "pep" of the bike when accelerating quickly. I am going to try and find this aadjustment when i get home. Any advise from you mechanical gods!
