Fouled plug pics...diagnosis please?

Recommended Posts

Here's what just came out of the old '11 700 Grizz...

The pics indicate some kind of build up on 3 surfaces...the base ring, and on both the electrode and ceramic opposite where the strap attaches. What condition does this suggest?

Also, this article...

How to read Racing Spark Plugs - Dragstuff

indicates since there's no color change in the middle of the ground strap that there's some type of temp problem. Or does this not apply as the article is talking about racing spark plugs?

Thanks

      1987 suzuki LT230E, manual shows the plug on the underside of engine. Not there. There's an access hole in the skid plate, but no plug. I see a possible plug on the backend of the engine case. Its not underneath but on the low part of the case. Facing the swing arm. Is that it?

      Well today i was working and seeing if i could get my suzuki 160 running. I took the plug out to clean it or see if it needed cleaned. It was covered in oil. Black thick oil. If i heated it up i might of been able to get a drip off of it...(it is like 35 degrees right now). It also clanks when i crank it. The clank is always in the same spot. It never it in a different place. It will turn over but work fire up and idler. It was idling but now it wont. Could i have bad rings or compression. Maybe a head gasket. The top end has a layer of oily filth on it.
      Is having to retighten the chain every few rides normal either? It seems like the chain is always lose.

      hello everyone. I purchased a second hand honda foreman 450. I thought I found a diamond int he rough, but it appears to be a rough diamond. haha. My problem is related to two wires under the right rear fender above the tire (see pic). The wires are cut, and I'm unsure where they go. One wire appears to be yellow with a red stripe, the second appears to be a brownish color....... originally I had a green with red stripe wire, and grey wire cut, but I located those and re-wired them. Any help would be appreciated...... I hope this is related, but the iginition switch (neutral light/lights) don't seem to respond. I can crank the quad by arking the cylanoid, but i assume it has something to do with these wires. any help is appreciated. I just need to know where the wires go.
