(This is a hypothetical situation, but not unusual.)
Let's say you acquired a Drifter that has been sitting in a garage for multiple years. All fluids are full... gas, oil etc. Assume a fuel stabilizer was used, but you don't know when. No charge on the battery. Tires are old, but otherwise in good shape. Assume relatively low mileage for age.
1. What steps would you take to safely get this bike back on the road.
2. Specify 800 vs 1500.
1500
1. Drain fuel and inspect tank
2. Replace battery
3. Replace oil
4. Inspect/replace old tires.
5. Use PM schedule to perform other maintenance.
6. Use injector cleaner, check out fuel lines and fuel filter.
800
Same as 1500, except add. 6. Rebuild carb. 7. Inspect/lube chain.
What have I forgotten?
I'll add for both: Check out electric connections and wires.
Looking at what I just did for my new-to-me 1999, I'll add: (Chief may have included these in his catch-all "do PM schedule" item)
1. change fork oil
2. replace brake and clutch lines
3. replace brake and clutch fluid
4. check fork and swing arm for bearing slop
5. measure fork springs and replace if sagged
6. check rear shock air pressure (1500)
