Dear fellow Airhead G/S riders, I have managed to land myself two '81 G/S machines in various stages of integrity. I hope to get one back to original spec and another "special" for riding. My problem is I did not get an Owners Manual with either bike. Does anyone have the '81-84 Standard R80 G/S Owners Manual on PDF? Anyone know where I could get an original tool set? Airheads forever!
