NAPA in Canada has Champion and Autolite non resister plugs that cross reference to the NKG.
Take those cross references with a grain of salt, NAPA cross referenced a plug to my Prius that wasn't even close to what it should have been. Threads into the hole seemed to be about the only commonality.NAPA in Canada has Champion and Autolite non resister plugs that cross reference to the NKG.
Gary, do tell us about your torching method.PS I use a torch cuz the ceramic absorbs oil, IMHO only a good torching will get it all out of the ceramic.
spray the plug with carb cleaner then torch for a spectacular event....
In case you were serious.Gary, do tell us about your torching method.
If you check your plugs a lot, you'll end up wearing out those crush washers long before the plug is worn. It took some searching but several years ago I managed to find Champion replacements (N-678) for cheap and bought a whole bunch.
I know Jim and others use spark plug sandblasters. Aside from not having one, possibly leaving abrasive residue in a motor scares me.
My research so far :Would it be noticeable on running if both resistor plugs and resistor plug caps were used?
Also other way, if no resistor in plugs or caps?
I was serious. Thanks !In case you were serious.
I use Bernzomatic trigger start propane torches, yeah one in the garage, one in the shed
This is a good quick why fouled plugs are a problem, with some causes video.
Since it's NGK they say they can't be cleaned LOL
This is short covers it pretty well, using a plug socket to hold the plug in the vice, brilliant. focus would have been nice.
minor quibbles
He might be slightly overheating it, for me electrodes red, not white hot. Does a good job moving torch around, the critical part is the nose insulator, want to get it clean/white as deep as you can all the way around.
If the plug is wet oily, start with some carb cleaner. NOT brake cleaner!!
After torching I may use a thin scraper (windshield wiper stainless steel strip ground to fit and scrape).
I like a fine stainless wire brush to finish up, I'm not a heavy scrubber, the porcelain is porous, rough, you don't want to leave a fine layer of conductive stainless steel worn off the brush wires on the insulator, a good reason not to use a soft brass brush.
Blow any gunk out with compressed air.
I seldom find bike plugs with electrodes that are very worn, rounded off. But as 5twins hints; sparks prefer sharp edges to jump from. So rounded edges require a bit more energy to fire. You can file an electrode to get a sharp edge back.
Check your gap before you reinstall. I like those round gauges.
OK the brake cleaner thing. it is a big deal.

There; the 9 yards version.
repeat; if in doubt change it out. plugs are cheap.
PS if you suspect your motor was flooded cranking it with the plugs out can get rid of a fair amount of raw gas, dry things out a bit. 'Specially good idea with 2 strokes that may have a slug of raw gas sitting in the crankcase.
If the motor, carbs are cold a hair dry to warm them up a bit can do wonders getting a motor fired up.
