I'm a new member but have read a lot of helpful things in the past now I have a problem I haven't found the answer to yet.
I have a 2015 sportsman 800 over the last two or three weeks it would start to spit and sputter a little sometimes but go away for no apparent reason yesterday rode it for 30 minutes to a friend's 2 hrs later wouldn't start hauled home trying to find problem.
I have fuel spark and compression have looked at all connectors and wiring nothing obvious stands out.
No codes on screen when. I try to start it it acts like no fuel getting to cylinder I'm assuming something electronic isn't allowing injector to open. If I open throttle while cranking it backfires in air box.
