Correct Spark Plug for K

[jtauriello]

First post here. Hope I am following rules correctly. I am trying to find a cross reference for spark plugs that will fit a K, i.e., H-D Champion, NGK, etc. Also, looking for correct socket size. Thanks.

NGK 6BL short reach, 1/2", should be a good start... It's sort of one step better than a moped sparkplug...
