I don't think you can get around fully disassembling the bank of carbs if the bike has seen storage with fuel in the carbs. Those little idle circuits gum up even a bit and the idle is ruined and you will even see some hanging/floating of revs when you rev it. Separate each carb from the bank, remove the parts in the float bowl (needles, jets), remove the CV boots and slide, anything rubber, then soak the carb body in one of those gallon paint type cans of carb cleaner with the little metal cleaning basket in it. It says on can how long to soak it on the can (40minutes?). The cleaner will eat anything rubber or plastic, along with fuel residue. Reassemble and set everything to stock, maybe an 1/8 turn richer idle, then it will idle great.
My cbr 600 shuts off at idle at every red light while at normal running temperature. I changed the spark plug and new oil but same problem. Any suggestion?

Great video man I appreciate it
Interesting….I wonder if the carbs were looked at when the aftermarket exhaust were fit! Just a thought. Keep up the good work. d2R

Sounds like a vacuum leak to me mate, check all the vacuum lines In around the carbs and airbox
@@callytech.d2r813 thank you buddy I'll check it out and let you know
You'll work it out cal
What would you look for it it sputters
I would check the basics
Check for vac leaks
Check the carbs are clean and jets are clear
Check carb sync
