Question
I was just wondering if you know of any online stores where I could get a spark plug for a 1981 Honda xr80. all of the places i have looked don't carry them. thank you

Answer
Cory, the spark plug is a NGK C-7HS(A) which may be superseded by a CR-7HS or you can use a ND U22FS

Not sure why local Honda dealers or M/C parts houses wouldn't carry one of them. It is a pretty common plug.

The CR series of plugs are resistor plugs. If you have resistor spark plug caps and resistor plugs it might be too much for the ignition system, depending on how strong all the parts are now, after 28 years.

Google "NGK C7-HS" and see many other sources for these plugs.
