It is as if the injectors have increased the fuel on their own causing the bike to travel on indefinitely apparently. This may also occur in Sport mode, but I can not presently recall.
I can see where this might be helpful in competition but I don't like it and would rather the engine braking continue until I did something with the throttle or clutch to alter the closed throttle situation. I've asked the service tech and he says there is nothing to be done about it.
There is a thread hereon which suggests that this behavior is what the slick plug is all about, and if so fine, but I'm in Race and have the same behavior, i.e. injectors working with a closed throttle.
Perhaps someone can explain the purpose of this: emissions, etc.
With the standard ECU, the bike switches off the injectors when engine braking. Results in quite alot of engine braking, and saves more fuel than you think. However, in order for this to work IRL, the bike has to start injecting fuel again at some point before
reaching idle, in order to prevent the bike from stalling when you engage the clutch while not idling.
This results in some bumps when you get under 2500tpm. Further increasing your problem could be a badly remapped bike, or the lack of.
