I'm looking for some ideas or modification's that will improve gas mileage. The mileage I get is in the normal range for a 1200, the bike is a SEI so it weighs a ton, is fuel injected . What I've noted is when I decal. the exhaust fumes smell a little rich. plugs look alright,tailpipe is blacker then I'd like. I have a K&N type air filter, started using ATF in the gas and I'm trying that spark plug mod. that you remove some of the ground electrode. I don't have any gripes about how the bike runs, starts right up, all the power you need I'm just looking for some ideas to kick around.
