When I was pulling with the 81, I would switch plugs and clean the used ones after every pull. I had about 3 sets I rotated in. I will only do this with Autolites, however. The Champion plugs don't seem to preform as well after a cleaning as when they are new. So, I have 3 sets of AL plugs, collecting dust because I found the Continentals (after a little trial & error) actually run better on Champions. Only thing I run them in are the old L Heads.

I have a drawer full of old spark plugs.
I thread them into the holes when I paint an engine.
That is the only time I "re-use" a spark plug.

Most of the time I clean my plugs with a spark plug cleaner http://www.google.co...29,r:3,s:0,i:86



I have a spark plug cleaner something like that one,and it does a nice job on the plugs. Sometimes a plug is no good though,and has to be chucked.

if the plug is working ok and looks good, I will clean them (abrasive cleaner like described) and put them back in. If diagnosing ignition problems, I always start with a new or known working plug.

Back in the days of 2 stroke dirt (and street) bikes, seems like I was cleaning plugs all the time! But 90% of the time they would be fine once cleaned up.....
