Guys, thanks a ton for your time!
Ok....After some hands on checking, here's the scoop. The bike does not start without the clutch lever pulled in when the clutch lever cam adjuster is in positions 2, 3 & 4. My bike does start WITHOUT the clutch lever pulled in if the cam is set to position 1 ONLY. Now the factory setting for the clutch lever cam position on the Busa is position 2 (and can be increased, depending on the adjustment needed to complete the diode switch circuit, further to normal wear, I presume). Set her on position 2 and she now starts (with the clutch lever pulled in at start) and runs fine. I suspect position 1 was throwing her into neutral mapping.
