Guys, You have no idea.  Even though it's an inanimate object, you become attached to something that you've had for forty years. That's longer than I've been married!  I bought it as a kid because I loved the lines and I had followed Cook Neilson and Phil Shilling's 750SS racing stories in "Cycle" magazine.  I never anticipated that it would become so valuable and because of that, less fun.  I recently sold an old Porsche 356 for partly the same reason.  I used to take both the car and the bike everywhere.  It got to a point where I couldn't do that any more.  Those factors combined with my health made me realize it was the right thing to do.  At 66, your priorities change.  Time and your health (besides family and friends) are the most important commodities in the world.  The rest is window dressing.
