ya i pulled these plugs, they are still good right? maybe a little cleaning?

 

check the electrode in the middle.
if they were mine i would replace them.

 

replace em

 

yeah electrode on the far right looks worn

 

just replace them dont try to clean

 

As everyone else already stated....replace them. Plugs are so simple and easy to swap, and not a big expense to buy....don't cheap out on them, just get new ones.

I get new plugs for my beast every 6000km abouts, some may think its a waste but whatever, keeps em new and in perfect shape at all times.
