Ditto on what the others said;
- change the oil and filter
- service the air filter
- inspect, lube and ensure the chain is properly tensioned
- replace and flush brake fluid and bleed the brakes
- make sure the acorn header nuts are torqued to spec
- replace the tires and tubes.
- check steering head bearing adjustment
- go over all other fasteners to ensure tightness
At that point, I'd be comfortable taking it for a ride. The doohickey should be done at your earliest convenience; do NOT attempt to adjust it. With 2200 miles it PROBABLY hasn't self destructed which makes replacement much easier.
A suspension service should be on your next "to do" list; take the rear linkage apart and lube, same with the pivot bolt. I'd also add a thermobob at some point if it was mine but that can wait if the budget is tight (though the benefit is highest the lower the mileage). After that there are dozens....no, hundreds of other mods you can
do to make the bike better for what you want or need.
I bought a 2000 a couple years ago with 577 miles on it; I did the stuff above and the bike was perfect.......I needed a battery too. My tires had almost full tread at that mileage but
....now how about some pics?
