[QUOTE="Magnetoman, post: 106614, member: 2806"] For what it's worth, with the pre-Monobloc carburetor on my 1928 Ariel whose only tuning consisted of polishing the needle on the float so fuel wouldn't leak out of holes on the bottom of the carburetor body, the best mileage I got on the Cannonball was 79.2 miles per U.S. gallon (99 miles per Brexit gallon). Second best was 75.2, and worst were 51.4 and 49.4 mpg, the latter riding into stiff headwinds. I had geared the bike high and kept to a pretty steady 50 mph average. I started out using the highest octane fuel I could find just to be safe, but in Iowa I was confronted with a pump that had a selection of about a half-dozen ethanol mixes, none with an octane rating listed, plus "normal" 87 octane. I used the 87 and then stuck with it for the rest of the Cannonball because it seemed to be fine. That advice is completely wrong for the reasons I gave in my previous post. [/QUOTE]
