I am another user of 15W-40 (Mobil Delvac MX), also had UOA done on this oil with great results.
My riding is never above about 85F in the summer and down to around 35F in the winter. Not overly hot.
In the transmission I have used in the past Redline, too expensive but good, Formula + good and the Delvac also good.
37k miles on my engine.
If I were you in SoCal I would use 20W-50 grade.
Cheers
