Aside from the valve-clearance check, I'm not sure if main-jet changes would do much for your MPG. You may get better results from adjusting pilot-screws. Those plugs look rich, but not as rich as my street-bike under WOT.

I run 110 mains and get 235 miles to reserve. You might be right but an increase in mains does result in an increase in fuel throughout most of the operating range. Hence no shims on my carbs?
