I've been using champion N5C as a plug without issues but looking at the owner's club spares pages it lists the following
Champion L86C (L10): 1941-46 350cc with iron head
or
Champion N5C spark plug: 1950-63 all singles with alloy head
or
Champion L82C (L7) 1945-46 500cc with iron head, 1947-50 all models with iron head
The description for the L82C is a tad ambiguous but I think It covers my bike. Can anyone confirm this is what I should be using as I must admit I thought it odd that the threads on the N5C were longer than the thread in the head.
Thanks
1947 350 HW which plug?
