Default Cleaning Spark Plug

     

I fouled a plug (Relized I was riding my YZ like a 4 stroke because I was afraid of the power band ) What can I use to get the oil and everything off of it?

pj1 makes a electrical contact cleaner that I used when I had my kx100 and it cleaned my plugs up really good. You might also want to try and get a hotter plug, while your still getting used to the kick of the powerband, just dont run it wide open for a long time with that plug.

The lower the number the warmer the plug, eg. a BR8EG is cooler thatn a BR7EG in the NGK plug nomenclature. Just curious, as cheap as a standard NGK or ND plug is why not buy a four pack and have some handy?

Oh well I looked at my manual and my dad ordered the suggested plug, and they only came in 10 packs. I really should get a hotter plug until I get really get good enough to be in the power band most of the time.

Check Rocky Mountain ATV/MC or even an auto parts store. We have gotten them at Advanced Auto Parts.

Ok this is a really stupid question, but do you consider a plug fouled when it is coated with oil to the point as to where the bike wont start? Or is it when you pull out your plug and it is black. Mine is black...but my bike still starts.

If your plug is black and still running, sounds like you need to work on the jetting a bit. It could be a bit rich. Although from what I've read, that's an indication of how the bike was most running very recently. If you want a better indicator of jetting, you can take an old plug and cut away at the threads so that you can see the insulator tip. You're looking for a tan/brownish color (highly technical terms here). Black indicates a rich condition and a light tan or white indicates lean. I believe anyway. I could be totally wrong here.

If your bike won't start, you pull the plug and it's black and wet, I'd consider it fouled then.
