That said, while it doesn't give you another three gallons' range, I'd also be checking into why you're only getting 110 miles to reserve.
Well, I'm averaging about 27mpg. times 4 gallons is 108 miles. I've had several tanks of gas that I only got 21 or 22mpg. I do have a tendency to twist a little hard. but what should I be getting? the bike has cobra 6 into 6 pipes, I don't know what air filter it has, I need to pull the tank an look.
Maybe I should show up to a tech day when the carb sync kit is available. I don't know maybe that would help some.
