First time for everything

[Aelwulf]

About three years ago the bike started exhibiting problems similar to those that you describe.  It basically acted like it was running out of gas with two and half gallons of gas remaining in the tank.  Turns out the 20 year old fuel pump needed rebuilding.  The process was cheap (approx. $20.00) and easy.  Bike immediately ran like the good old days.

That's possible.  It's nearing the 20k mark and I'm rather highly doubting the last owner did it, and considering when it supposedly was last used before him it theoretically probably wouldn't have needed it then.  I'll try to keep it in mind as another step to be done.
