Look At My Plugs!

[ClimbAnyHill]

Why are my plugs wet & black. Idle sits low. Not getting enough PING & doesn't sound crips.

Haven't done a plug chop & dont' know my compression yet, my tool is broken.

What clip should my needdle be at?

I'm running:

Stock Engine

T5 Exhaust

Tors Removed

K&N Pods

320 Jets

27.5 Mains

Airfuel Screw out 2 1/4 turns

They are going to turn black eventually. do the plug chop test.

I run 270 mains with 27.5 pilots and needle on middle clip on my .60 over stock motor with pipes, airbox with no lid but I am at 0 elevation, you should for sure do a plug chop that way you know for sure, but that seems like it would be a bit rich IMO.

My brother has fmf fatties and power core 2's with the airbox completely cut off and he is running 310 mains and 27.5 pilot and everything else is stock and he's a little rich at glamis, your plugs look a little rich if your looking at the porclein part it looks a little rich.

looking at the pics again it looks like 1 plug is ok and the other is rich, that could be because carbs arent in sync

plugs do go bad after awhile i would get new plugs and try it out i bet it will run like you remeber it. if you have been mixing alittle rick latly it will eventualy foul plugs.

320's sound rich for sure.

[ClimbAnyHill]

I think it is running rich.. Stock airfuel screw should be 2 turns out. I'm thinking of the following.

2 1/2 turns out

300 jets

 

What clip should my needle be at? I'm getting in there now. Thanks.

Are these plug pics from a WOT run, or did you just ride around, shut it off, and pull the plugs. If that is the case, you plugs are normally gonna look like that. Adjusting the airscrews will dial in the jetting up to 1/8 throttle or so. Anything above that is handled by the needle and main jet. I would start with the needle in the middle groove. Also, have you done a compression check lately? Please post some plug pics after a WOT run, and we can help you better.

This is what i ended up with. This is the best I could do with the cam. What do you guys think?

 

Thanks for your help.

Those plugs were from normal running. I just posted what my new plug looks like.

Thanks for your help!!
