Hello all: I'm in need of a running 250 L6 but will take a 230 or a 292 in a pinch, I'm in San Francisco and would like to buy within a 150 mile radius of town, excepting the ocean part of that radius, of course. Also looking for a good harmonic balancer for my schvitzed 250, 3/8 inch, any number of grooves is fine--the woodruff key rolled in the keyway so I'm also interested in the later model bolt that holds these on to the crank end. thnx, Brad 415 424 6139
