So far I've got de-smog, Twin-Air filter, removed air-snorkel, and the carb mod! I went with K55/158 and a .024" shim. Fuel screw out 2 1/4. I just took the bike for a quick spin and once it got warmed up it pulls much harder! I've heard people can do wheelies in 2nd from 1/4 throttle without using the clutch or any tricks...I can't. Is it common to be able to get the front wheel off the ground? Or are those guys running different sprockets? Or, do I need to play around with the fuel screw? Bike took a little coaxing to get started, does that mean it's still on the lean side (I should I turn it out another 1/4), or could that just be cause the carb was out? I want rolling wheelies in 2nd!!!! What size sprocket should I get? I rarely go on the highway and 70-75mph tops is fine. WOOHOO!
