Local ride to day on the CBX when BAM high idle syndrome starts! LOL.

If you hate it, give it away. Let me know when to pick it up.

"Carver Tape" - the equivalent of leaving the protective plastic on the livingroom furniture...
(Get some 3M paint protection film.)

Air leak someplace in the intake manifold? Try squirting WD40, very carefully at all the junctions between the carbs and the heads to locate the air leak. If the problem is neoprene intake manifolds that have got hard with age, they can be softened by soaking them in oil of wintergreen. I use Hylomar gasket sealant, applied just thick enough to be opaque to all surfaces.

Process of elimination DC. Are you sure the t-cables are returning freely?

I agree with George, make sure there is enough slack in the cables to let it return to idle and don't mess with anything until you hear back from the carb guru. Remember the trouble shooting flow chart. The first question is " Did YOU touch it"

Did not change or touch anything.. Just rode it..

Carb guru, Jack Wagner, quote.. "Carb Sync". We do the best we can on the bench, but sync on bike is highly recommended..

I just purchased another CarbTune Pro so all 6 discrete carbs can be monitored.

In the meantime, chasing KZ1300 issues.. and the poor ol KrZy8 lays sitting waiting for lift time and a plethora of parts...

What's strange about those 40 year old motorbikes is how badly they perform compared to today's bikes.
My nephew completely rebuilt a '72 CB 750 last spring. Now remember those were "cutting edge" machines.

The frame flex, weak brakes and just general instability at 70 plus is crazy. But we hammered the hell out of them because they were so much better than their predecessors.
