Good question...I just got the tbike pipes too. Ran 130/42/3 turns. Seemed a little lean (plug centers are white) and lotsa popping. Went to 135 and 3 1/2 turns...popping is much reduced, but still seems a little lean on the right cylinder, so I broke down the carbs and gave them a good cleaning and synched em' (I had bought the bike in Dec...who knows how long it was sitting with fuel in it)...waiting for a clear day now.
