Rode my bike Friday parked it, got off, came back 2 hours later and it sounded like crazp (V-twin). Guessed my plugs were bad, changed them out today and WOW!!!

NGK P/N: CR9EHIX-9 Stock: 6216

 

Holy giant picture batman!

 

They're probably still good for another few miles. Put them on E-Bay.

 

I will post them as gently used, never been wheelied, one may need to be refurbished soon, but if u have a V-twin, YOU ARE IN LUCK!!!

 

Totally the spirit, it's all about the sizzle, not the sausage.

 

Holy huge pics!
You have a significant oil leak/consumption problem in that one cylinder, don't you?

 

I'd say one and four would best be donated to a local charity shop. The other middle two...well I suppose you might get lucky and have them snapped by some installation artist or someone equally as deranged.
Couldn't you make the pictures a bit bigger, I needed a frigging magnifying glass to see what you were on about.

 

About the oil leak/consumption, I have no idea. If someone could enlighten me that would be great. I am not great with understanding that stuff, especially plugs, but I know how to change them. Took me about 3-3.5 hours from start to finish with cleaning/washing all of the fairings, not too bad I don't think. I went thorough the front, behind the radiator.

The plugs are OLD, and by old I mean about 5 years old and at least 6,500 miles(I would guess). 2 of the 5 years the bike sat and would randomly be started by my father while I was deployed overseas.

 

I just see free oil on all plugs' threads, but specifically I was looking at the huge carbon build-up on the far left-side plug.
