Cruising speed?

[KEITH KRAUSE]

Smaller RPM at cruise will likely cost you more fuel, as the throttle will be open farther to go anywhere, the engine is not as efficient when it's not in it's correct powerband.
A 550 should get 50 mpg, if it doesn't fix something.

I know what you're thinking but the lower rpm's will more than compensate for any wider throttle opening. Mileage will be better if tested under same conditions.
I've known riders who ran taller gearing and each one of them said mileage improved. I've read the same in mags and on TV and even heard it talked about in shops.
I generally don't fully believe ANYTHING unless I've been through it but everything I know of the subject says taller gearing will give you better mileage, especially whan used as this member intends...cruising.
