I am thinking Mobil 1 full synthetic, and wonder the clutch will slip under hard acceleration and during changing gear.

Will it happens? The clutch now slips once a while under certain condition when I notice it. someone pls tell me pro and con of clutch slippage

Yer clutch will not slip with JASO-MA certified oil....unless there's something wrong with it.

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

Went full Honda synthetic. Found it for a good price, filters are cheap. But I'll bet you could abuse this engine and it would run perfectly unless neglected. As for the rest, I have noticed this bikes bit more sensitive to chain adjustment to my Shadow. So I keep up with that.

Agreed

Absolutely true. Keep that chain at about 1" to 1-1/8" slack and you will be very happy.

If you insist on Mobil 1 synthetic, use the motorcycle specific variation because bikes have a wet clutch. Automotive oils (synthetic and dinosaur) have additives which ruin wet clutches.
I use Honda GN4 motorcycle oil.

I'm reporting this thread to the moderator immediately! Its an outrage...an oil thread on our nice, friendly forum.

I mean the clutch sometime slips during gear change from 1 - 2 - 3 when too much gas and very quick release of left hand, my fault. the clutch won't slip at all using half blend synt oil.

the oil now still very clear, before changing.

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
