I have a 2014 Honda rancher 420 es. About a month ago I was riding down the road and all of a sudden the motor died and as it was decreasing speed right when it got around 5mph the back tires locked up(still in gear). Well I pulled it home and let it sit for a week or two because I don't have time to work in it. Pulled it out the other day and it won't crank. I pulled the top end off and everything looks good. I'm getting fuel to injector, I got good compression, the plug is firing as normal, I put new gas in it, I chagred the battery and still won't crank. It'll act like it wants to crank sometimes and but never starts up. It'll backfire occasionally when turning over. Any one have any suggestions??
