Can anybody give me an idea to why my 07 predator 500 wont start. The engine cranks but it wont turn over. I've put in a new spark plug and charged my battery. When it sounds like its about to start it backfires. Any ideas that can help.

 

Check your choke. Is the gas old? Could be a plugged jet.

 

Have the valves ever been adjusted? Bet the intake valves are too tight.

 

I've never had the valves adjusted. What else do you think it could be?
