TygGer, where in NoVa do you live? I'm right in Gainsville and work in Tyson.
If you need oil I would recommend going to Fast Lane Cycles in Chantilly. Their number is 703-818-8890. Don't worry if you hear female voices. Their front counter has a couple of ladies working there. /images/icons/wink.gif Whatever you do don't go to Power Ride Motorsports (formerly Coleman's), they charge way to much for everything.
I would recomend going with Motul semi-synthetic oil (5100). It does wonders with Yamaha's gearbox! It makes it nice and smooth.
Drop me a line and let me know if you want to go riding sometime. I'd also be happy to show you how to change the oil on the bike if you want. I do all of the work on my baby, well, besides mounting tires. What kind of bike do you have? The picture in your profile doesn't work.
