That is Cooolll. Thank you
Surface cracks usually don't affect the function. Kyle's point.
Exactly but someone has everyone fooled taking advantage of them as far as I am concerned
Agree. Just have never seen one cut in half. Seen them cracked just not cut. Cool.
Great photos Kyle! Think the white stuff is some sort of epoxy which never cracks. Simple fix for outer skin cracks....run a bead of silicone caulking along the crack and go for a ride. Those outer cracks don't affect anything.
Whatever the white stuff is it is very hard. I tried to stick a pick in it and it was hard
Hey Kyle, so was the black plastic cracked, but the white still keeping the coil intact?
If so, think of all the coils that got/get tossed on that visual inspection alone.
Yea ,I want to check out the video when your done.
Yep just the black plastic . That white stuff is hard as a rock ! I don't think it would ever crack. Yep tons of good coils get tossed.

Kyle, when you say hard is it like porcelain or more like a plastic do you think?
Either a plastic or some kind of bad ass epoxy
IGN Coils are typically filled with epoxy.
I worked at an automotive supplier that made coils and represented another one that made coils.
I'm so old I was still selling oil-filled coils to Chrysler in the 1980's!

I was one of the people that my V max kept dying in the rain . I bought a set of used coils but nothing changed . I even went to the trouble of shielding all four of my coils with aluminum foil and sure enough it kept on dying in the rain which aggrivated me more & more because my 900 Kaw never missed a beat in rain , ice or snow . I gave up thinking Yamaha failed when it came to severe weather conditions . For me this info & video is nothing less than a God sent revelation . So now we know ! A new set of plug wires would have solved the equasion & got me home instead of all the missery I have endured . Don't know why I wasn't smart enough to replace the plug wires , but I'll fool myself again by the fact that it ran so good until rain stole my fun & joy ! THANKS AGAIN !
