Alright, fathers day started out great, got to sleep in and got some sweet cards on the night stand when I woke up. Lets fast forward to the beach. Im out riding the superjet after installing a new wear ring, midshaft, and coil. I put the coil from my last SN I built that had maybe 5 hours on it. (I believe this is the culprit). I was riding for about 5 minutes and almost rolled the ski over, it is now running on one cylinder. I figured I injested water or something. I try to get it to go but it wont go anything over idle. I wait for my buddy to show up b/c I didnt bring tools, (why would I it always runs great) lol. I pull the plugs, they look fine, I'm getting spark so I put it back in the water. Takes off like a raped ape, then about 5 minutes later it falls on its face and the same thing, wont go over idle. At that point I say F it and just start drinking. I get it home, go to flush it and it runs like a top. My question is before I go swapping parts is what do you guys think it could be? I've heard bad things about the MSD coils, and after it doing it after not rolling it I know its not water injestion. Could it be the CDI? The coil? It seems like it gets hot and then loses spark on one cylinder. I will first try new plugs and then try puting my old coil back in but wanted to see if yall had ran into something like this first. Thanks guys.
