My husband has a 1991 yamaha radian and he needs to change the spark plug. He doesn't have the repair manual so does anyone know what the gap specifications are for his motorcycle.
Does anyone know what the spark plug gap specs are?
If you buy NGK plugs from your dealership, they are pre-gapped to that spark plug's application. The gap might be VERY SLIGHTLY off, but it will work fine.
