I sell one or more bikes each year........BUT......I always have my original K3 ready to go......Hope you made some $$$
A friend just found a near original CB75K5 in his neighbor's garage.....$250.
He got it running in less than an hour and sold it to the son of a long-time K1 owner for $800......sans the original exhaust. He says he will keep the remaining original tank and covers on the shelf and do a mild cafe build. Only 16xxx miles.
