Motorcycle Repair: Honda xr80r

Question
I just picked up an xr80r, I believe it's a 1982. There was no spark plug in it, can you give me a number? Anything else you can tell me about the bike would be greatly appreciated! Thank you!

Answer
Paul, using eBay for a search engine I found "Honda XR80 spark plug" listings to show:

CR7HSA to be the preferred spark plug.

The original platform was the XR75, way back in 1973...
