Plugs

[rmk2112]

Is this normal? looks like its burning hotter on one side of both plugs.

Reason I ask is....while riding on Fri, I experienced some bog and a quick "check engine" flash at each bog...lasting for only a second. The sled has run perfect except for this one incident. It did it while turning and climbing a steep hill in warm, wet weather (Temp was normal - 125*) It would happen when I pinned it to climb a section of the hill. It happened a 1/2 dozen times, then I didn't see it for the rest of the day. That hill was the last time I really pinned it tho too.

Any ideas or comments?

Same plugs, reverse angle

I agree, slightly leaner, but I think he is asking about each plug. It is normal for the intake side to be lighter and the exhaust side to be darker. That is why the race guys index their plugs.

Ahh, OK. Thank You

So, I'm guessing that the bog and light I experienced has nothing to do with the plugs then.
Any ideas on that??

Have you checked TPS setting?

Yes, it was adjusted and set about 4 weeks ago at the dealer during some work being done. Its run flawlessly since.
