Here is a small spark plug cleaner:

Clean Me

 

The easiest way to un foul a plug is to torch it. Put the plug in a vice and run a torch over it..good as new.

 

wow!i never heard torching a spark plug can clean it......sweet im gonna try that next time.

 

Why not just go out and buy a few extra spark plugs and a wrench, it'l cost like $10 and you'll hve a couple extra plugs on hand and a wrench to switch em out with. If the bike came with a tool kit you should already have a spark plug wrench in there.

 

what i do is i zip tie an extra spark plug and wrench to my frame just incase it fouls while im ridin.....its already saved me...lol

 

I sliped an extra spark plug and extra pack of fuses (when they blow they will ruin your day) in my tool kit, also took out the cheap socket in there and out in a spark plug socket and stubby rachet.
