XS1100 gets as good as 30 mpg. Plugs are black. Long history. Stock airbox. Jardine 4 into 1. Stock pilot jetting. Stock main jetting. Genuine Mikuni jets. Everything is stock and clean.
The bike starts right up. Idle is good. Acceleration from stop is good. Runs like butter all through the RPM range. It's fine riding slow or fast. I should get about 40 mpg and not be looking at black, sooty plugs.
I believe I need to tamper with fuel level. For better economy, do I need to decrease or increase the fuel level in the bowls? Whatever is wrong, is wrong across all four.
