This week, I tackled the throttle cable first. Since the bike has clip-ons and a Triumph engine in a Norton frame, it’s been a bit of trial and error to get everything just right. The cables from the carbs to the junction box were straightforward, but finding the right cable from the junction box to the twist grip took a bit longer. Eventually, I found that a Norton Commando 22 1/4" cable fits perfectly. With the carbs balanced, they’re now all good to go.


Next up was the wiring harness. This required a lot of planning and problem-solving. I opted to use a '72 T120 Lucas wiring harness and modify it to suit my needs. I cut the alternator feed and created my own wiring feed, as the original was in the wrong place. I also modified the harness to work with a different ignition switch and to match up with the Wassell regulator/rectifier, which will be mounted below the seat plate. The Pazon ignition box will also be mounted there. I wired the box into the harness using some of the original coil wires. The single coil is mounted up front near the headstock, so I’ll use an earth feed from there. With these single coils, all I need is a feed wire from the ignition box, which saves a lot of extra wiring. The feed from the ignition plate will run under the frame, protected by heat shrinking and extra heat-resistant tubing.


For the battery, I’m using a smaller unit located in a small box under the seat hump. I decided to set it up with a quick-release connector so I can easily plug in a trickle charger. I also wired in my preferred type of fuse, which uses a small blade-type fuse with a built-in circuit breaker. It took a lot of head-scratching to figure out the best way to wire in the regulator/rectifier, Pazon box, ignition switch, and battery setup. Using some excellent Japanese-style terminal connectors, cloth tape, and waterproof terminal connectors, I think I’ve come up with a pretty decent result. Time will tell when I get to turning the power on.
