I use my neighbor's carb book from Sudco.

On some carbs you can put the choke on a little and try to recreate the symptom and if it's better, then you need to richen the pilot jet/cutaway/jet needle/needle jet/main jet depending on the throttle opening of the problem. (If a problem is RPM related it is probably resonance mismatch in the airbox or exhaust, but if a problem appears at a certain throttle position, it is probably carburetion.

BUt as I said, I refer to a book myself.

Is the LC-1 a controller for injection or a meter for carbs? The way I read the site you'd probably want the LM-1. But I really don't know anything about Innovate or their products. I, too, want a wideband sensor and meter because the fuel/air ratio can be wrong for a short time in some situations where it's hard to determine if the bog is lean or rich.

DO NOT STOP building wacky bikes. They entertain me. You can send me one if you'd like.
