Honda cb750 f2 1978fault on old bike ! electrical problem

Hi, Can anyone help ? when running at speed for a while if I shut throttle down fully (and i think mainly suddenly) the engine stops and all electrics die totally. No electrics, (no lights, ingition, power) no nothing. Pull bike up and about 30 seconds later electrics return and off again. Bike has just been put back on the road after a couple of years stored in a garage. Just had a new battery whoch is fully charged. did cut out for fractions of a second when running at speed a couple of times. Definately electrical and not fuel. Hoping to use bike or holiday so urgent help appreciated. Thanks ! honday 750 f2 not 1992 but cant find that model.

From your explanation it sure sounds electricals, but surprising to hve a total failure to the electricals and thn it reappears after 30seconds!
Best would be to go through the wiring especially frm the battery onwards, the fuse box .
Since it is totally disappearing it should be a fault to those main wires could be lose connections somewhere!.
Hope this helps.

Removal of honda cb750 ignition switch


Most Honda ignition switches can be removed by unbolting one side of the head light, swinging it out of the way, reach up with a 10 mm socket on an extension, and unscrew the two bolts holding it in place. Once you pull it straight down you can unplug the harness from the base of the switch and remove it from the bike.

I'm not familiar with that make/model, but if it has a brushed motor then it is likely that you have a faulty controller module. Most brushed motors have just 2 wires running to them from the controller.
