4. Plug Types for British Motorcycles

We have had good results with NGK plugs and some suggested types for popular machines are listed below. The NGK plugs have a good heat range so the suggested grade will usually perform well for most normal riding. If you have a modified motor or you are competition riding the suggested type can be a good starting point to find the best grade of plug. Use the gap recommended in your machines handbook. If you don't know the recommended gap, 0.020" (0.5 mm) is a good starting point. A large gap is not necessary unless you have plug fouling problems.
