i have a polaris explorer 1999 500. the problem is we rebuilt the motor and replaced the cam. now it won’t start. we finally put a timing light on it and it reads 11 degrees out. any ideas of how to correct this.

I thought all the Xplorers were 2 strokes. 250 and 400 engines. If you have a 4 stroke then I don't think you have an Xplorer. The 500 could be a Magnum or Sportsman. Either way, the method to change the timing will be to move the stator plate behind the flywheel. Going back to the basic things though. You have spark, fuel and air? Compression is correct? Will it pop and fire on starting fluid? If you want to know exactly what you have, post up the VIN and we can run it and find out.

In 99 there was a 500; Scrambler, Sportsman, Magnum and 6x6

All the 500 engines (EH50PL) spec. timing at 30* BTDC @ 3500 RPM

11 degrees is not off enough to prevent starting - 11 degrees advance is about normal at cranking speed - 11 degrees retarded will make starting easier, but will hinder acceleration and high speed performance
