81 S&S for $4500. 351 with a Powerslot, looks like it might have a 4-blade. Last picture in the ad- prop blades look too close together to be a 3-blade.
No pics but at this price it might be worth looking at, especially if someone's interested in doing a restoration.
Later model engine cover? An '86 for 7K.
Lots of other MCs in the bay area, including an X-80!!
