I have about 2 gallons of leaded Sunoco 110/ 91 pump mixed 50/50 with motul 800 @32:1
This Sunday at Oakland sx futures I broke my leg and I am out for 8 weeks. How long until the fuel goes bad? Will the unmixed fuel be ok in its 5 gallon drum?

I can only go by what the race gas companies tell me and that is good enough. There has never been a study to show gas goes bad in 2 weeks like so many say, then it becomes some sort of internet law. If people want to throw out gas because they "feel" it's bad, then more power to them and you Barn. Makes no sense to me, even those that sell the gas say it lasts a long time stored in reasonable conditions and not in some faded plastic can, in the back of a pickup in the elements. Clearly there are conditions that warrant it not being used, such as described above.
The rest of the unmixed fuel is in its original 5 gallon steel drum.

And there is still no reason for you to think otherwise, so try and keep up the good work!
Exactly what fuel is the other 50%?

Every 2-stroke manual I have ever read stated to mix the premix the day of the race. This is because once mixed, the oil begins to lose its lubricity due to oxidation. With that being said, I'm not sure how VP is making T2 that is already blended? Maybe they are nitrogen blanketing the container or they are just making the assumption that if there is no headspace then the oxygen is not present for the oxidation, which is a bad assumption. Or maybe they are adding an inhibitor which helps prevent oxidation of the oil, which is most likely what they are doing. Which ever is correct, VP or the 2-stroke manuals, VP seems to be successful selling the T2 premix fuel without problems.
The 110/pump should be ok if the metal can has been sealed up. The 50:50 blend has reduced the ethanol content to around 5% most likely and the water adsorption capacity would be significantly reduced.
Definitely drain the fuel tank and float bowl on the bike as both of those pools of fuel are subjected to high water absorption due to both containers being vented.
And my "chopper" even came with ape hangers from the factory!
