i found with mine, that if you used 91 octane you get worse gas mileage than with 87, you also have to remember the KZ models are old and when they were running the streets the most common gas was 87 octane 91 was pretty much race fuel. so if you want better mileage i would probably go with 87.

Not really. Fill up with the "correct" octane when you run some fuel out of your ride.
