1400 miles started about 500 miles ago. i tried jumping it,still wont start. do you think its valve adjustment.

 

On this late model of a machine don't dive into it past a certain point. Check for spark,check fuel pressure,basic stuff. Shouldn't need valves adjusted this early also. Manuals are high for this model if you want to try to do your own work. I'd get a manual from Polaris on this or let Digital Wrench find the problem.
