Well, first step was installing the new manifolds with the crossover tube. Not one other change. First kick start (like normal). The motor Idle speed was about 800 RPM higher (around 2K). Reduced the idle, let the motor warm, backed the pilot air screw a half turn (2 turns out), adjusted the idle down to around 1.2k and went for a ride. Complete difference in how it runs from 2k to 6k at part throttle. Still responds well at full throttle but maybe a little softer. It started raining so I returned home after just a couple of minutes in the lower gears. Need more time on the bike, but my immediate assessment is the crossover tube has a similar effect as leaning out the low and mid range fuel circuits except the same good throttle response still seems to be there. Then from 4.5k to 6k all the rich blubbering is gone, but no surging or bucking and it makes a really smooth transition into the power band past 6k without the abrupt hit. I think this gives me a good baseline to work from.
