Bill, you are killing me!
How DID you know that the past week I've been revisiting pics of my old SR500? What an excellent motorcycle! Mind you, I'd like it better if you found me a '78 in good condition. That was the only year (mine) with a rear disc brake.
If I could justify another bike, I'd look for one for sure. Sold mine for $1300; not so much less than this guy's reserve. The owner had a BSA thumper already. Single most fun bike I've had. And I really liked that 'kick start only' feature in a late 70s bike.
