Here are the top 5 parts that should be replaced on your vintage Honda (or any old motorcycle) that is being made road worthy again.
It may not be obvious but these parts are related to the safety, reliability and ride-ability of your Honda CB350 / CB360 / CB450 / CB550 (and their related family models). These bikes are 40 to 55 years old, parts like these decay and wear out with age regardless of how they may "look."
All other parts are subject to inspection but the top 5 should always get swapped on any bike that is going to be ridden.
