That's very interesting Roger, & obviously a lot of detailed investigation and work.
I feel compelled to comment on how deeply that simple aspect intertwines with the provisions of "self tuning" and in particular (and my case) the MS technology.
Just to know what my old lump was doing with its original Bings (sorry for airhead content) I ran the original LC1 on the bike and documented afr behaviour at various temperatures and load/ speed conditions. To be fair, jetting and carb condition enters into results but with the bike running "very normal" I was shocked at how rich it would sit on cruise, and how lean it would transition towards on hard accel.
Everything to do with "inherent performance & behaviour" changed once the Bings gave way to injection and forced induction, but learning what AFR the bike likes is just a process of trying out different settings (on all states including idle, mid accel, hard accel, cruise, and decel) where all can be changed independent of the other. I find I can lean out to 16.5 easily in cruise with no surging or transition hiccup, as well have recently been playing with an economy tune to allow 87 octane while maintaining detonation free hard accel driving (our gas getting so expensive lately). I believe some megasquirters just seek out excuses to meddle with their tune, as it is perhaps too much fun
Roger, thank you for the detailed info!
So what have people been finding is the optimal AFR to run for an RT?
