Q. My bike runs normally when I first start out, then a misfire begins. WATT could it be?
A. Do you have any codes? Anything like a flashing area of the dash and maybe goes away?
Q. No. Would I need to have it diagnosed at the dealer and have their download device notice a parameter out of spec?
A, Yes.
Q. So how do you explain that it runs fine in the beginning, then the misfire begins?
A. You rule out fuel because it runs fine in the beginning.
Q. WATT am I left with, spark?
A. Yes. The sparkstick finally heats up at max temp sitting in a hole that has heat around it to boot.
Q. The next question is, how do I find out who failed if it's too hot to pull the sticks under heated conditions?
A. I'd use something like a hairdryer or heat gun. Checking a cold stick might match the others. But if you heat the body and check the prong ends with a multi-meter, you might have a different reading. Whoever is not matching the other 3 sticks and their (heated) values, that's your culprit.
Magnetism = You cannot separate HEAT from the chemical reaction.
Since the stick-C is a coil of wire wrapped around a core, it's one continuous wire in and wire out; are the two prongs at the stick. Heat has to chemically induce a path not at the plug. At some point at that unbroken path, a resistance has occurred due to heat.
AC/DC = For every action there is an equal/opposite reaction. DC still has this opposite effect, but AC is the equal swing back in this (equal) reaction event, or WATT separates A from D. The coil is pure AC so would/could I detect a carbon build of that chemical reaction of black powder on the plug end? How about plug meets stick and that touch point? Meaning, since the stick is going to spark and ground someplace, it might ground from which it came in other words...I'd look there for the one stick on the misfire. No need for a meter/dealer download.
