Will do.

Probably won't get to adjusting the carbs for a week or two.

Also thinking about making a little bracket with, say, some strapping to hold the carbs stable and in-place.

Right now, without an airbox to provide any stability, the carbs are "floating": held on the front by the stiff rubber plenums (correct term?) and nothing else on the back.

I am wondering if the action of rolling on the throttle causes the throttle cables to torque the carbs enough that maybe I am getting an air leak at the plenum.

Has anyone with a air filter pod and floating carb bodies seen this problem? has anyone made a bracket to secure the throttle bodies to something other than the rubber plenums?
