I have a 74 cb350f that had the engine completely destroyed. Recently I found a 400f engine in pristine working order that I swapped myself as a first time big project on this bike. The bike was running great as everything went smoothly so I took it out yesterday for a first official ride that wasn't up and down my street when finally all power was lost after 5 minutes of perfect riding. I tried kick starting and the downhill neutral to gear start but it wouldn't budge.
I thought the battery was just dead as there was no electricity anywhere so I charged it up and made sure it was fully charged but I am still getting no power on the key turning ignition no lights no kick start no nothing. From my quick inexperienced glance every connection seemed in check as well so I am at a stand still.
Anyone have some ideas?
