I don't know of this update, but if it's out there and you take the bike to a dealer for anything and they see there's a ECU flash from Kawi due, they will flash it. I'll go to the back and check with my service dept.Fox, what update? Your making me nervous right now LOL
I think you are right because my Mustang does this too, but between gears when shifting. We do think it's emissions related cause the tuners can't get it out.I bet it is an emissions issue. A rapidly closed throttle cause the combustion to emit a lot of junk (NOx I think), a lot of cars do this same thing.
