Ah ha...yes, you are getting hooked on the foot clutch! It almost seems illogical, but I sure did miss it when I traded off the knuck. Sometimes I would even fantasize about converting my BMW...!!! But that would have been weird. I'm glad that you "get it", many would not, and could not.
I would agree that your oil light issue is just that...the sending unit, or an oil light issue. However, if you just took the bike for a ride, got it good and warmed up, then put the gauge on in the garage and fired it up, it would reassure you that you have enough pressure. I don't think you would have to actually ride it with the gauge on it. Makes one love roller bearing lower ends even more. !!!
Shifting with the throttle hand makes no sense to me, even though some bikes were set up that way, back in the day. I'm sure one could get used to it...but...!!! Of course with my set up, I'm not sure how I could get my right hand down low behind me on the left side.
I guess if I let go of the bars with both hands I could contort myself enough.
Oh yeah, I forgot about the leaks. Yep, when I see a drop or two under my primary case, I know my oil is circulating, and
the front chain is getting enough oil. Two for one.
