15.8 is not 16.3 that is required for 50wt, but it is a lot closer to 50 than to 30!

alum of 25 seems kinda high but your motor is still under 5k at the end of the uoa. could be clutch basket or shift fork material.
the copper of 14 is the same and probably is clutch basket bushing as there is some tin as well.
the iron of 7 is on the low side for that many miles on that new a motor. so that is very good

all in all a good uoa and no real reason to change what you are doing unless you want to.

20w50 is awful heavy for this time of the year. What is the factory recommended grades?

Here's a glimpse from your manual.

"Engine Oil (4-stroke)
Engine Oil Level Inspection
NOTE
This vehicle's engine is filled with 20W-40 oil
from the factory. DO NOT DRAIN and refill
the crankcase before use. Check oil level and
drain plug tightness."

Sounds like a 20W40 is called for.
