This is why Pulse&Glide works quite well on my BMW F650CS, even without instant feedback (the earliest feedback I can get is at the pump).
OTOH if you look at my log (Teresa is my bimmer) and sendler's (Honda CBR250R FI Single is his CBR, not a big surprise
) you can see some difference in their FE, he can do 80mpg with the CBR around freeze point, while I'm in the low 70s even at the low speeds I can hold in cold. I often ride at 50-60km/h (~31-37mph), in 4th (because I have to) at those temps, so the engine efficiency must be pretty bad, but at least the aero drag is lower...
