Just changed my spark plugs for second time. 2014 Chieftain 116 BBK. To my limited mechanical knowledge, the older plugs looks like things are well with my motor. Left plug front cylinder, right plug rear. Those of you more experienced, I do welcome your thoughts.

Look very good to me. Probably could have kept on going with the old ones. Dean

Out of curiosity, how many miles are on your bike, and on that set of plugs?

Looks good to me too. Rear plug looks better than mine did.

@TerryJ have you been using an octane booster?

Good question. Once in a great while I will. I had a good dyno two years back and it runs smooth, but still pops a bit on deceleration and sometimes pinging on acceleration but usually just Lucas injector cleaner or PI cleaner from Amsoil

I just noticed your plugs have a rust/red color, which is indicative of octane booster use.
