4K oil change - which one?

[_imp]

Just use Honda Full Syn, 10/30, can't go wrong

Honda does not have a full synthetic.They have Honda pro
HP4 which is a Synthetic/Petroleum Blend.
Furthermore cars use 10w-30 viscosity not Motorcycles.
I don't have a clue as to why Honda recommends 10w-30.
Especially when Honda motorcycles tend to run hot.
Hondas also take a while to warm up.
I ran Amsoil 20W-50 in my Rune for about 3 years due to
Hondas running hot.That viscosity helps the engine in the
summer.
Motorcycles today have different tolerances than those of
30-40 years ago.So engines today don't need such cautious
break-in as in years past.Even though Synthetics are thinner
and therefore more slippery,new engines aren't breaking-in with
as much internal shavings of parts.However I must admit,when I
drained the oil in my CB at 60 miles because the glass sight
indicator was reading totally full I did actually pick a few
black speck shavings from the oil drain pan.Like where did they come from.
I was almost flabbergasted when the Honda dealer I bought my CB
from { I never used this dealer before } had Amsoil 10W-4o on
their shelf.It says right on the container it is " wet clutch compatible " and is SHEER STABLE. Also :
- No friction modifers for outstanding wet clutch performance
