OK r.e. jet sizes- if Mukuni runs about 10 smaller than Dyno for equiv. sizing according to the "matrix", does that mean that a 37.5 Dyno pilot equates t oa 27.5 Mikuni pilot? I run stock pipes, K&N in the airbox, and rejetted to a 140main/35pilot Mikuni sizes, and it still needs 1/3 choke to roll on w/o stumbling. Above 1/2 throttle it pulls well. Vibrates a lot now, too, and backfires a lot. Mechanic also adjusted the fuel pump rather than the shims and raised needle, as it reportedly didn't run well. Could it be that I need a much smaller pilot?
