Wiring is always a treat, unless you use one of those systems in a box like Phil’s speed shop systems. I ran one on my factory racer, and it was a breeze. I’ll try to find a photo. It was designed to mount to the frame seat post. Inside it contained the circuit breaker, the starter relay, the ignition switch, the starter button, high low beam, and horn button. Then a ream of wire rumbled out of a hole. I guided them to the appropriate spots and hook them up. Nothing to it.
In this case, we worked with Wire Plus since they are the masters of wiring kits, Speedos and assorted equipment. They sent me a complete wiring harness with a starter relay, flasher system for turn signals, a 30-amp circuit breaker with mounting strap and rivets. They also included an installation and operator manual for model Wp192, Mid Frame Mount System, with Chopper style harness, with or without turns.
Their manual affords the reader a lighting circuit flow chart, an ignition flow chart, and an accessory flow chart. It demonstrates several ignition switch wiring circuits and handlebar circuits. It even comes with a Wp143 lighting control system for auto-canceling style harness. Actually, I checked the Wire Plus web site and they do make a seat post ignition switch wiring system unit, in a coffin shape, classic, and old school. They also make a cylindrical shaped engine mounted ignition switch housing, and ignition and toggle switches. They have systems that include compression releases–Amazing.
Wire Plus also makes individual wiring products, like their lighting control modules, power modules, plus custom power ports, for plugging in accessories. There’s a reason for going on and on about Wire Plus. Wiring can be a nightmare, and I’m a lazy. I want to be as minimal as possible, for ease and reliability, but I’m fulla shit. Just about the time I think I need to cut turn signals out of my system, someone is wiring in heated grips, or a heated seat, a some sound system, or neon lights under the engine. I avoid anything extra, like the plague. Hell, wire plus make engine mounted electrical port systems, so you can plug in your heated vest, helmet sound system, or whatever.
This is going to be a terrific test. My son’s bike will contain more bells and whistles, and Grip Ace controls in the bars. Tim from Grip Ace from Rivera is coming over to show us how easy it is. On Frank’s bike, we will install turn signals, so anything is possible. We will also wire a metric bike, the XS Yamaha bobber. So, over the next couple of months you will witness three variations, with Wire Plus products.
I start wiring by finding all the components and placing them somewhat in position. Then I search for a place to hide the circuit breaker and a circuit board, or bank of connections. First, we made a trip to the local Marine store and ordered an ignition switch. This included a starter switch, but we were using the Spyke push-button starter mounted to the solenoid. It eliminated the starter relay and any starter switches.
Once I determined a handy location behind one of the Mudfap Girl FXR panels, I drew up a wiring schematic, while referring to the Wire Plus handy manual for guidance. I came up with this nuts notion of hiding the ignition switch under the seat nose, which would position it perfectly for some of the wiring, and run some of it through the backbone of the frame. I grappled with a mounting notion, but Danny came up with the final notion, which took a lot of work, but was highly secure.
Wire plus makes several digital speedos, and several mounting systems for different applications. It was a breeze to mount and wire once I found the mysterious neutral switch connectors, which I ordered from the factory. The WP speedo mounted like a dream on the bars, once I plugged the wiring harness into the rear of the unit, ran the wires under the tank, back to the nerve center for power, then to the speedo sensor, and the neutral switch. Nothing to that one, although I wouldn’t mind running the wire loom through the frame in the future.
Since I was thinking about the rear brake pressure switch, I started to work out my GMA brake systems, and we made some measurements. I ran over to Baker Performance products and in five minutes we had new brake lines cut to size. This was probably the easiest bleeding process I have ever encountered. They were bled and working in no-time. Unfortunately, GMA doesn’t make a clutch lever to match.
On rubber-mounted bikes, I run two grounds. I welded one to the frame and I use one of the Spyke starter mounting bolts as an auxiliary ground. I don’t want to take any chances with the charging system, or the ignition system missing a grounding connection.
I needed to mount an On-On switch in the headlight bucket. It took some hunting for the correct sized switch, then a headlight seal beam from Biker’s Choice, and a lot of digging for a three blade connector. My headlight came from a spot on a police car in the ’30s.
Almost all of my electrical components came from Spyke or Compu-Fire. The Compu-fire ignition system is a breeze. This time I’m running a Compu-Fire single fire ignition system, with their single, dual wound coil, which mounts between the heads, in the standard stock position. It’s all too tight and convenient. Two wires to the coil and one to power and the system is good to go. It’s about that easy to time.
My son showed up with the missing parts for his Bub Bare exhaust system, and we started mounting it. I wish the exhaust guys would make kits with the flanges and retainer spring rings. Some systems come complete, but it’s a drag to run to the dealership, when you’re ready to rock. I understand why they don’t supply them with many system. If the system is replacing a stock system, we just switch out the parts. And these four pieces would jack up the price, but give the customer the option, and the manufacturer could make an extra buck and save the builder time and hassle.
This system slices damn close to $350 and you paint it with whatever heat paint, or heat wrap you like. It’s very similar to my D&D system.
