Gapping spark plugs

[Burnerman]

Iridium spark plugs for a Honda Blackbird, around £16 each getting a little cheaper now. Centre electrode the diameter of a hypodermic needle but they still last around the 20k if I recall.

I worked on a Honda CRF250 (done a fair few steel valve conversions on these actually).

£40 for one spark plug!, NGK R0451B-8. Shocking really..
