Yamaha gp1300r spark problem!!
I am needing a little help from anyone who could guide me to a spark situation on a 06 gp1300r. I recently built it up and has great compression but for some reason, it only sparks in cylinder one. It will spark every here and thier in cylinder 2, and no spark at all in cylinder 3. I have replaced coils and cables thinking that might be it and still nothing. I also replaced the water temp sensor and nothing has changed. I have no idea what else to do at this point nor do I know what to check. Please help

pull the stator cover and look at the pickups and flywheel

I have the same issue with my 1100 stx di machine. A couple of days ago it just died, come to find out it doesnt have spark to cylinder 1, cylinder 2 has constant spark, and cylinder 3 has off and on. The first initial crank i get one spark in 1 and 2 though... Have you figured out what the problem was?

I figured out the problem. It was a bad flywheel. I changed it and now it turns on like nothing. Im looking forward to take it out this weekend comming.
