1972 Yamaha XS 650:

Hi,
Came across your site few months ago. I'm 16 years old, and have been working on a 1972 Yamaha XS 650 of my own. Found this bike in the back of my dads shop. Pretty much just a tank, chassis, motor, and rear fender. Stripped it down, cut the backbone to rake it, lowered the front and back down, and have done some other things. Runs a 650 motor, relieved and ported heads, 38mm Mikuni's, custom tuned straight pipes, and a constant loss ignition system. I hope to take it to Bonneville speed week in 2009, when I get out of highschool. By then, I hope to have the Shell Thuett heads and cam, that we have in our shop,  on it. Only ridden the bike once, and it idles at 20 mph. Gassed on it, and it pulls like a top fuel dragster. It twisted the bars it accelerates so hard.

Thanks, Marty, - Marty's Speed and Salvage
