[QUOTE="Magnetoman, post: 111923, member: 2806"] Returning to AFR measurements, after having set the jetting of my Competition and Catalina Gold Stars using my Innovate-based instrumentation package, this week I had the first opportunity to measure their fuel consumption. I rode the Competition through 9 miles of stop-and-go city traffic and then another ~30 miles up a twisty road at a reasonably sporty pace to the top of an 8000-ft. mountain, while a visitor followed on the Catalina. We swapped bikes at the top and rode back down, stopping at a filling station after having covered 72 miles. Remarkably, the Competition got 69 mpg (83 miles/UK gallon -- since you're leaving the EU I won't bother converting to liters since you'll never have to use that Continental unit again after next week...) and the Catalina got 79 mpg (95 mpUKg). For comparison, an "eco-friendly" Toyota Prius is rated at 50 mpg for combined city/highway driving. For ~60-year old motorcycles with not-new Amal carburetors to achieve 40-60% [I]better[/I] mileage than a modern, eco-friendly sedan is remarkable. This shows that when you use an AFR meter to properly adjust carburetors for performance, you get eco-friendly as a bonus. Your motorcycle, your wallet, and the environment will thank you so using an AFR meter is a win-win-win situation. [/QUOTE]
