Welp 4 hours yesterday and another 2 to three today.
Yesterday
Set tire air pressure dead on.
Clean and lube the chain.
Change the oil and filter.
Lubricate the cables.
lubricate, clean and adjust rear brake.
Polish the chrome.

Today
Replaced front brake pads.
Adjust valve lash.
Fix oil leak.
Clean engine.
Replace spark plug with one of those 'E3's'
Polish some more chrome.

Notes:
You can run A F'N ton of Slime in a motorycle tire and not have issues.
Slime is amazing at fixing bad leaks though it sometimes requires a little finesse.
Still running Rotelle oil.
My bike seems very happy with a slight overfill of oil.
Front brake pads wear out fast.
Intake valves were dead on but exhausts had ate up nearly all their clearance.
Keep your engine clean to keep cool.
I know some say high octane is a waste. My owners manual says 91 or better.
In Texas you have 87, 89 and 93. At least at my station. So 93.
And when I get really hot I get a tiny bit of predetonation so... 93 octane.
It's more resistant to predetonation due to hot spots caused by carbon build up. That and it burns slightly slower.
I'll let you know if I notice a difference with the E3 plug.
I did notice a difference in my old hot rods when I went to high end plugs
so I'm hoping I get that here.
My old NGK plug came out reading slightly hot but in the ok range.
A white-ish coating.
