Visual inspection, a lot of years of experience etc etc and so forth.
Plus they were NGK plugs so I knew they would give problems.

Hard to see cat whiskers with your eyes, or were you under a microscope and still couldn't see anything? I normally check them this way.

With so many years experience etc etc, why not recommend something better, now?

I used Autolite, Champion, AC and some other green colored things as a kid. Started running NGK in the dirt bikes and fouls went way down. Never turned back. The new NGKs I get have a different plating but it does not seem to be causing any problems. IMO, from the 70's Champion was the worst. My bikes and sleds were rich running oil pigs and nothing lived for very long, so it was hard to blame the plugs. I used to take a dental pick and clean out the whiskers or take propane to them.

I remember a friend's old Yamaha had twin plugs in the head. One was a spare that you could swap the plug wire over once the first one fouled. Seems like another friend had one like this as well.

Other day the neighbor was trying to clean out his yard with a blower. He was pulling and pulling. I asked if he really wanted to get the yard work done or was just trying to put on a good show for the wife. Turns out, he really was trying to do some work. I headed over with some tools. 2-stroke. Had a Champion plug. Pulled it out, cranked it over, no spark. Pulled it over a few more times to air out all that raw gas and wiped the plug. No fire. Gave it the half inch air gap trick. Crack. Intalled the plug, with the gap, one pull and shes fires up. Let it warm up and push the boot down. Good to go. He may have been running 16:1 for all I know. He just looked at me funny and said I never saw anyone do that before.

New oils are much better and I doubt the 2-stroke bikers have the same problems we had as kids. The only bike I have now that fouls is the GSXR.

Saddle warmer,
The electrode is probably seperated inside the plug insulator.
This is one of the standard ways a plug can burn out. Especially on a high heat motor like air cooled motorcycles.

What brand and type was it? You see alot of disdain for NGK on this forum (Dink) Was it NGK?

it was a NGK D7EA. the po put those in. put a brand new NGK D8EA in. Will replace the others and see what happens. Not sure whats in my 1100. it runs good, easy starting, i'm going to check what is in it tonite. the plugs in the 1100 have over 2000 miles on them that i know of. we'll go from there.

So let me see if I get this or not! You cannot accept that anyone has a different opinion than you?? I PERSONALLY and professionally have only ever had NGK plugs dud out, get over it, especially if your experience is different. Remember this thread asked for opinions.

BTW no I did not look for "whiskers" it was an NGK plug so I was witing for it to crap out, I knew they would, I may have previously stated my opinion here "NGK are crap"

>So let me see if I get this or not! You cannot accept that anyone has a different opinion than you??

Accept? You mean take something said or written as truth without data to back it up? No, I am not in the habbit of doing so.

I was looking for data was all. You talk about all of your experience and I was asking you to share it. Most "professionals" are willing to help out those of us who are less gifted.
 
I put NGK iridiums in mine, it idled a little better, no other noticable gain
