08 Honda rancher 420 problems

I have an 08 Honda rancher 420 2x4 that isn't running at the moment, the bike isn't getting spark, I changed the spark plug and when I took the spark plug out and tried to run it there was no spark, any suggestions to what may be the problem with my bike. I think it may be the coil but I'm no expert mechanic.

    Coils on Honda's aren't known to go out, normally it's something else but not always. You did rule out the simple checks such as kill switch position and main fuses? Also was the bike running or did you buy it not running as a project?

    Yup, checked kill switch and changed all fuses, I had it running about a month again then it just died and I haven't been able to get it running since

    I would inspect your CDI for any bulges or cracks, also if it has a burnt electrical smell that could be your problem. If it is indeed your CDI check to make sure your voltage regulator is charging at normal voltage. A bad voltage regulator can cause the CDI to burn up because the it can't handle the extra voltage that would be coming through.

    Does the fuel pump run when you turn on the key? Do you have a shop manual and multi meter to do some testing? Has it been ran in the water a lot (plans for the snorkel)?

    I would get an OHms meter and a manual and start testing your electrical components to help locate the problem. Look over your wiring harness just to make sure nothing could of possibly chewed on it and look for signs of heat damage.

    It's inside the rear case. It hold your flywheel in the right spot on the crank. If it sheered an move any it won't run right or at all

    I would start with taking all the connectors apart in the bucket behind the battery. I get a lot of problems from that area from either water or rodents. If those are good I would do a peak voltage test on the CKP sensor (pulse generator). Also check the plug on the regulator, sometimes it will short enough to cause a "no fire" situation.

    I haven't had many problems with them on the 420's but yes it's possible.
