Condensation or head gasket

Light brown oil after winter

I have an 03 hayabusa. Started it up a couple times during the colder months( I live in ny) went to do new coolent and new oil to have it sit for the rest of the winter and the oil is a light brown color. I've been reading a couple forums I've seen it can be condisation from the winter months and starting it up, using mobile 1 in the cold or the dreaded head gasket. Looking for some insight on it or if anyone else has had this problem. Thank you guys

I think head gasket (never seen this color and I would never start with that so good you took it out, maybe heat some on a spoon and see if water is present?)

But starting in winter without driving means it does not reach operating temp and so no water was removed from the oil by idling.

Maybe put some of that oil in a jar and see how it separates at room temperature (oil floats on water after a while) and maybe use a bit of new oil with coolant to see if you can replicate?

But condensation in the cold is a lot when looking at months of time. When around 0 degrees celcius more condensation was visible on my fuel-tank and engine.
I keep the fuel tank full to prevent condensation inside.

And when replacing the air-filter my GSXR1000 had to much water in the crankcase breather filter, maybe check the air-filter box?, it has a drain that was dry.
The small

I don't think it can drain back from filter to engine, but maybe...

GSXR1000 :

The GSXR1000 2014 airfilter water drain was dry, so that is not really an indication to me:

Add water to oil, still kept going:

Yes, imagine trying to start it with the engine full.

I know nobody who does this and when I bought my 1000 the owner also had a busa in the same storage and I think if this oil problem was normal there would be more info?
Looking at the picture I can not accept this is just and only condensation, the mix is 1:4 water I think, so a full liter of water.

Anyway the storage text from the manual, thanks for mentioning that and it definitely shows there is more (now thinking if I should do this next winter)

If your motorcycle is to be left unused
for an extended period of time, it
needs special servicing requiring
appropriate materials, equipment and
skill. For this reason, Suzuki recommends
that you trust this maintenance

2. Run the engine for a few minutes
until the stabilized gasoline fills
the fuel injection system.
1. Pour one tablespoon of motor oil
into each spark plug hole
. Reinstall
the spark plugs and crank the
engine a few times.
2. Drain the engine oil thoroughly
and refill the crankcase with fresh
engine oil all the way up to the
filler hole.

3. Cover the air cleaner intake and
the muffler outlet
with oily rags to
prevent humidity from entering.
1. Remove the battery from the
motorcycle by referring to the
BATTERY section.
2. Clean the outside of the battery
with a mild soap and remove corrosion
from the terminals and wiring
3. Store the battery in a room above
