Would like to hear feedback from anyone that did re-jetting/mods of an Amal 36mm carb.

Changed the pilot jet on mine & it brought air/idle screw from 3+ turns out to about 1 1/2 turns.

Carb seems to perform well enough. Always (before & after pilot jet change) had bubbling/backfiring at closed throttle, between shifts, full deacceleration, when turning bike off.

Has anyone dealt with these issues with any any degree of success?
