Try balancing ans syncronising the carbs.
BALANCE THE CARBS
Turn the throttle screw on the LEFT carb one half turn inward. Now start the engine and get it warmed up. With the engine running, remove the RIGHT spark plug wire. Adjust the idle speed on the left carb to the point where the engine just can't quite stay running and dies. Now put the loose spark plug wire back into place.
Now turn the throttle screw on the RIGHT carb one half turn inward. Restart and rev the engine. Next, remove the LEFT spark plug wire. Adjust the idle speed on the right carb to the point where the engine just can't quite stay running and dies. Now put the loose spark plug wire back into place.
Turn the idle screw on each carb EXACTLY ONE QUARTER turn outward and restart the engine. The engine will be probably be idling very fast. Adjust both the idle screws equally from this point to get to the desired idle speed.
SYNCHRONIZE THE CARBS
Remove the air filter and rubber fittings to allow you to see into the throat of both carbs. You may need a mirror to see inside. You need to be able to see the slides go up and down when you twist the throttle. Now turn the fitting where the cable goes into each carb such that there is just a bit of slack in the cable, 1/16" is plenty. Lock ONE of the cable adjusters down tight. All further adjustments will be made on the other carb.
With the motor turned off twist the throttle very slowly while looking at the slides. Both slides need to begin lifting at the exact same moment. If the slides don't raise at the exact same time then slowly twist the throttle until the locked adjuster slide just barely starts to move. Hold the throttle still and turn the adjuster on the other carb so that the slide on that carb just barely starts to move also. Now recheck the slide movement timing. Do this process until the slides on both carbs begin to raise at the EXACT same moment. Lock down the loose adjuster and re-check the slides.
Please rate this solution. Thanks!

If you have used Dyno jet kit I have had a kit come through with smaller main jets than the stock ones causing it to run way to lean.

It sounds like you may have or will be jetting your carbs. I did this using the directions with the kit and used the Clyman manual for this bike to show me step by step how to remove the carborator. You will only need to attach 2 of the 4 hoses on your carb. syncronizer. If I remember right, you need to remove the bolt-on cooling fins to expose the engine block. The is a black screw or bolt that you take out and screw the threaded metal adapter of the sync tool. Be careful using the sync tool. Be very light on the throttle or the vacuum in the cylinder will **** in the mercury from the sync tool - not good. The problem you are stating on idle & backing off sometimes happens when the carbs are running rich (too much fuel) Hope that gets you in the right direction.

check valve clearances, and low voltage can cause backfire, battery voltage should rise when revved, use a digital multy meter
