I received a 1971 CB750 about 4 months ago for FREE from my friends uncle. It's in pretty bad shape cosmetically. It had no carburetors, no airbox, points and condensers were original, The spark plugs were older than i am, the front caliper is seized, the cables are all seized, there is a moderate amount of surface rust here and there (nothing rusted through), front forks aren't original, inside of tank is rusty, paint is faded and chipped on tank and there is a shallow softball sized dent in the side of the tank.
Two nights ago, after rebuilding a set of carburetors during the winter from the local motorcycle salvage, buying an airbox on ebay, getting new spark plugs, new points and condensers, a new battery, new fuel lines, a jimmy rigged gas tank, and a little starter fluid, vroooommm!!!! away she went. I am now looking forward to restoring this bad boy to rideable condition. It only has 12,000 some odd miles on the odometer (I know that's all it has, got it from the second owner) and it sounded great, no knocks, vibration or nothin...
It's the candy red/gold stripe on the tank 1971 cb750 four...
