Awesome, thanks for the info. I know this question sounds dumb (this is my first bike btw) but is there anyway special to open the gas tank up? I push down and turn the key but I feel like I'm going to break the key. EDIT: Screwdriver took care of the problem right quick and now it's working perfect.

Well to get straight to the point I just bought a 1978 XS400 for $20 from some guy in the pennysaver. He said it started and ran before he parked it 8 years ago. I want to get her running again and after giving her a good look over I've noticed it's not going to be as easy as I had hoped (is it ever?). So my first question is, does anybody happen to know a good website here in the states (Closer to California the better) that I could get some parts from? Just so I can kind of get a starting total of what it's gonna take to at least get the bike in putting around condition. Thanks in advance, I'm sure I'll be coming back here a lot and bugging the crap out of all of you during this project of mine.
