Many of you will be thinking duh, but I thought EFI was the end of needing to sync a bikes carbies. No carbies = no carby syncing. Right? Wrong. EFI throttle bodies are subject to the same need for vacuum balancing as carbies are. My bikes idle was steadily getting worse and I think I know why.

I find your ideas intriguing and I wish to subscribe to your newsletter.

What's wrong is you're using a carb balancer on an EFI bike. You need one that looks identical to what you have except has EFI BALANCER written on the backing board. EDIT: .

Nah look forwards to seeing if this helps. Bleed screw wrong on #3 but ok on everything ese?

I use a Morgan Carbtune....for carbs as well as the DFI on the turbo.

Your pic above shows your throttle bodies are not far out off sync...so this may not be your problem.

There is every reason that EFI throttles should be balanced just as carbs need it - same symptom, same reasons, same solution, same procedure...
