having issues with my 2012 sportsman 500 have about 18hrs on it. starts hard first thing in the morning choke no choke doesn't matter will fire after a few times then cuts out .crank it a few more times fires cuts out then repeat the same . after about 7 to 9 turn overs it will start the runs fine. let it set a few hours same thing all over again . seems worse in the morning . 90 degree weather should it be starting this hard? for the first ten or twelve hrs started just fine usually within the first two turn overs.It just seems to be getting worse any thoughts would be appreciated.
