Here are some pics of my plugs before and after the bump. The pics with 2 plugs is before the bump and the single plug is after the bump. I put about 100 pretty hard miles on it after the bump. My concern is the dark spot on the side of the plug. Why would the plug burn like that. The bike has 2000 miles on it and I am the only owner and the only performance/engine mod is a V & Hpropipe. I bumped the ECU 3 points on both cylinders. The current readings are Co 01 3 Co 02 0. Any info on the plugs will be greatly appreciated. The pics are in my gallery I am trying to get them here but until then here it is.

If you mark each plug for it's cylinder (front or back) then snap a shot with all 4 in the same picture, you'll save space. Once its in your gallery you can copy it (right click on the pic and copy) then just paste it into your post (right click on the pic and paste).


Is this after the bump?

Good to know Arizona I will giv it a try. This photo is from the left side and the plug on the left is the front plug. The single plug is from the left side the back cylinder. I will try to post it the same way you were able to pull this form my gallery.

This is after the bump. What could have caused the dark spot on the side of the plug. Lets see if I got it right this time.

Have been running the V&H Big Shots for approx 8000 miles with the ECU @ +3 points and stock air box with Speed* filter.

HOW WOULD YOU RATE THESE PLUGS

Here's a set of NGK Iridium plugs that i put on @ 10,284 miles 6-10-05 while living in MI. Shortly there after i installed Churchey's VBAK to compliment the V&H Big Shots that were installed at 800 miles. I subsequently bumped-up my CO settings in the ECU for both changes and still run w/o a PCIII!

I replaced those plugs yesterday @ 28,728 miles 8-17-07 figuring it must be time even though they looked good @ 22,539 miles when i inspected the left plugs.

That's 18,444 serious hard miles later and they look like near new plugs. They out lasted my CPS [:0] [
