Description
Original ignition coils on early 650cc V-twins lose their punching power over time due to intense engine heat and relentless vibrations. On these classic carbs setups, a weakening spark leads to frustrating misfires, poor hot-starting, and sluggish power delivery. While cheap alternatives are out there, they regularly break down when pushed hard. We have upgraded our stock to these premium Japanese-built units, engineered with high-density internal components to withstand brutal conditions and keep your bike firing on both cylinders cleanly.
