My personal opinion . I want the throttle blades to be exactly the same PERIOD any multi carb motorcycle ( in my opinion ) wants the throttle angle to be the same .
on my bike I set them with CLEAN throttle bores and throttle blades . After you have set the tps V to .157 mV with the r.h. throttle blade closed , 0 contact w/choke kicker and linkage disconnected .
I go to the l.h. throttle and turn the idle screw tii it touches and add 1/6 of a turn . I do the same on the r.h. idle screw until there is no clearance , then I attach the linkage and turn the white knob until it will hold a 0.002" feeler gauge against the throttle . Turn the knob until the feeler gauge falls .
Then I call it good . Clean the air bypass screws , turn them in until they stop . Back out 1/2 turn for starters .
Then adjust the l.h. idle screw until you get 0.450 mV or 0,540 mV depending on who you want to listen to . Start it up let it get warm and see how you like it .
