Apply silicone dielectric grease to the coil terminals to reduce corrosion and prevent arcing. Make surethat the plug wires have tight fitting boots and theproper size terminals. If your motorcycle is still equipped with the original carbon core suppressionplug wires, this is a good time to consider a high quality spiral core wire set such as the Twin Tec P/N 3003 universal set.
WARNING: To avoid ignition systemdamage from coil arcing, never crank the engine while any spark plug wire is disconnected. Do not touch or connect any test equipment, including a timing light, to the coil while the engine is running.
