Routing the Plug Wires
Now screw on, and tighten the little top nipples for every sparkplug, if applicable for your type plug wires. See Parts List section above for details.
Put a little dielectric grease on the sparkplug tips.
Next you must use some trial fitting to find the best wire routing for your bike. Since throttle cable set-ups vary, crankcase ventilator set-ups differ, and fuel line routings vary, not all sparkplug wires will route the same.
I ran my rear cylinder wires from the left coil (photo above), along the frame backbone, and past the rear cylinder. Then I circled the wires back (in opposing directions) to each of the rear sparkplugs.
I ran my front, right sparkplug wire from the rear nipple of the right-side coil, circled the wire rearward-left, then ran it forward to the right-side sparkplug.
My front, left plug wire (photo above) was routed from the forward nipple of the right-side coil, around the outside of the rear nipple, then back and around to the front left-side sparkplug.
Once the wires are routed to your satisfaction, wire-tie them to the frame to pull them up off the rocker covers.
Tip: I only needed to use wire-ties for my rear cylinder, as my routing for the front cylinder automatically kept the wires up.
