Don't take this the wrong way but, WHY? I DO understand why, but it's not an airplane or race bike. I've spend a large portion of my life monitoring gauges so I don't crash and die, I don't want to do it on my bike.
If you want to do it the right way, your gonna have to weld a bung into the crossover.
I'm a KISS guy...
I've never used a Dyno on this bike and probably never will. I read the plugs and use a "sniffer" to tell me the fuel/air. That's close enough. I will err on the side of rich and call it good. I could care less about fuel mileage, all I care about is fun mileage.
I eat, breathe, live, love and ride motorcycles.
