Could you help me with a wiring issue. I am rebuilding a new wiring harness for my 1971 Honda CB750 and they look to be 16 and 14 gauge wires. Is there any benefit by using 12 and 14 gauge wires? Thanks Craig
You won’t end up with any benefit on the CB750 by upping all the wires. The maximum current capacity of the factory wires is plenty for all the circuits of the bike. There are a couple bike models I can think of where a few individual wires would benefit by being upped a size, but none of the small gauge wires run hot on the CB750. Just make sure the connectors are clean/new, and the fuses and fuse block are in good shape.
Cheers!
