my roommates outlaw is only a year and a half old and it is having trouble starting. it turns and turns but wont fire. if we pull it, it starts pretty good. if we boost it and crank it over for a long time it will eventually go. i'm thinking it could be his valves maybe? anyone have any ideas? and where do you check the valves on the 500 and whats the spec? thanks

 

Classic symptoms of needing to do a valve adjustment.

 

i just read a thread that said some of the 500 polaris have dual overhead cams and have buckets and shims probably similar to whats in my ds 650 and some of the 500 polaris engines dont, which one is in the outlaw is it the shims and buckets or can i make the adjustment without tearing it right apart

 

Yes the 500 Outlaw has the dual overhead cams with the bucket and shim. The Outlaw 525 has the screw and tappet design. I would give you a link to a detailed step by step instructions on how to do the valve adjustments but the mods would just edit the link out.
