i have a 2006 polaris outlaw that want start for some reason i have never had a promblem with it before i did sit for a couple of months so i cleaned out the carb first an went ahead an changed the spark plug it is gelling spark but an the piston is moving up an down i really dont know what to do now can any one help i guess it may be the battery not turning it over fast enough but i have kept it charged with a battery maintainer i havent tried to roll start it either will that maybe do it

 

Valve clearance has to be checked/adjusted more often on the KTM engine in the Outlaw and also the shim system on the Predator 500 than any of the other Polaris atvs.The manual says to check the valve clearance every 15 hours!! Intake and exhaust clearance sets at .005 on the Outlaw. This is the first thing that comes to mind that I would check. OPT
