Custom Wiring Improvements For Honda Cafe Racer Build CB750 SOHC + NEW Electric Workshop Heater | 30

In this video I improve the custom wiring on my project Honda cafe racer CB750 SOHC build, and as an added extra I treated myself to a Mirrorstone Aurora Infrared Bar Heater for my motorcycle workshop to make tinkering through colder weather more enjoyable.

For wiring improvements I used:
Waterproof Electrical Connector Set 352 piece: https://ebay.us/g4J9ql
Ring Terminal Electrical Connectors: https://ebay.us/rgT0Lk
Crimping Tool: https://ebay.us/uPDm7O
Bullet Electrical Connector Set 400 piece: https://ebay.us/hlyTrx

Nearly every time I have had on the road issues with a motorbike it has usually turned out to be electrical problems. Although I have had my fair share of running out of fuel moments too. 🙂

To head this off at the pass on this cafe racer build, I decided to give the electrics another good looking at, especially as I am now getting near to the time I will be able to ride this bike.

With the wiring being largely custom on this motorcycle, I'll only have my self to blame if the electrical system is unreliable. I tried to steer away as much as possible from weak or cheap electrical connectors, but equally there's only so much you can do when its not a factory wiring loom.

Largely, my intention is to simplify the custom wiring and make the routing and each terminal and each connection as high quality as possible, to prevent a future of frustrating electrical issues. Ultimately I'm in the UK, so whether I like it or not, at some point this bike is going to get wet in a rain shower, so I need to do everything I can to mitigate that and be confident that the wiring will survive it.

I did put quite a bit of effort in first time around to make sure everything worked well. But some of the peripherals, indicators and rear light etc where just plugged in and I felt could be better. I really wanted to do the full OCD job, making everything not only well connected, but with the wiring routed in a way that looked fantastic. It is great having these ambitions, but it pays not to be too disappointed when you don’t quite achieve them 🙂

I gathered together all of my different connector types and even bought a kit with a variety of waterproof connectors, which I didn’t use in the end. Got out the soldering iron and the hot air gun and got on with the job.

I know that a major problem point is always where the wires go between the frame and the forks and handlebars. This is a problem because the forks turn in relation to the frame, and the wire is always moving and needs to have some slack to allow this. The movement can cause two issues, one the connectors become disconnected, the second being that the constant flexing can cause breakages.

I took out the headlight and looked at the wiring in there and back from there to the frame first. I changed and shortened a lot of the wires so that there wasn’t too much of a “birds nest” in the headlight bowl, and the wire to the frame was adequately long.

Where possible I followed a convention of socket connectors on the live feed side of the wiring and bullets on the earth side, in an effort to stop future shorts occurring. I also where possible crimped and soldered the connectors on, with additional heat shrink for good measure.

I know I will probably have to have another look at some of the wiring in the future, but for now I think it is pretty good. You always think you could have done better, and improve all of the time. Keep watching to see if I do have any problems with it.
