Tomatocity, to get through EPA certification, the stumble is a lean spot just off idle that is worse in some bikes than others.
I never considered the lean spot off idle a problem though a factory mapping problem. Someone found the way around that with the clutch switch bypass or flashing the ECU.

Now I would be happier if they changed the limited throttle response in 1, 2, 3 to 100% without having to flash the ECU.

Yamaha should be concerned with the new 500 pound 1190 chain'r arriving in February.
