Sounds just like what has happened on a lot of Polaris 500s.Would recoil start,but not electric start. Pick up coil or flywheel magnetic tab dirty or distance too far. Don't know if this helps,but what one member found out on his atv. no spark to plug when using electric starter - Page 3 - ATVConnection.com ATV Enthusiast Community

Moved pulse coil to the point of contact an back ever so slightly. Marginal if any change.
Being I do see a spark, but not as strong as with the recoil, the amount I'm getting should still be enough IMO to start it. Being its a PAIN IN THE A#$$ to pull, I'm focusing on elsewhere. Spark, compression , fuel.. Valves set and carb cleaned.. Now to pull the pipe and see if some "critters" made a home inside, or left a cache of nuts/seeds which will stop the combustion process.. Will post back results

Pulse coil could possibly be weak. You said it had a "fresh" stator,but did you replace the pulse coil with it? Stator new or used? If you had the resistance specs on the pulse coil along with the stator specs,it would possibly help to narrow down the problem.This where a good service manual comes in.

another yamaha yfb 250 start problem is also the neutral switch, located directly behind the shifter, pointing down. if that wire is dirty, frayed, it makes the neutral light flicker and they wont turn over or barely turn over, but you can pull start the quad or even jump the solenoid and it will fire.
