I have a 2006 polaris outlaw 500 and it wont start, but it has good compression, valves are seating fine, getting fire, fuel and air. Dont know if its electrical or what. It back fires alot but other than that cant find anything wrong. I have a feeling its electrical but cant figure it out. If anyone has had the same problem or can help please let me know!!

 

The Fuji 500 engine is really finicky when it comes to starting and valve adjustments. Double check your valve lash and make sure they are in tolerance.
