1971 Honda CB450 K4 - Return to Stock - Part 2

In this video we wrap up the return to stock transformation of our Polynesian Blue Metallic 1971 Honda CB450 K4. We reinstall the original carburetors along with a pair of reproduction air filters from Scrambler Cycle. We also convert the bike over to LED bulbs and make a diode sub-harness necessary for the indicators to function properly. We’ll take a look inside the original fuel tank using an USB inspection camera and a laptop. And finally we’ll fire it up and take a final walk around.
