Some motorcycles with high compression, large displacement engines, or Single Fire ignition systems may have difficult starting. In most instances this is because the starter motor draws more current than the electrical system was originally designed for. Under these conditions the voltage at the coil may be so low that the spark energy is insufficient to fire the engine. Daytona Twin Tec's ignition power relay kit solves this problem by supplying full battery voltage direct to the coil. Kit includes a high quality relay, wire and all required terminals.
