Arctic cat back firing!

[enticerboy48]

Hi everyone i have a 2002 Arctic Cat 300 4x4 that wont stop back firing! I have cleaned the carb several times and put gas line anti freeze in the tank, but that does nothing. I took the bike to my arctic cat dealer and they put a lid on the top of the carb that did nothing for me! I NEED HELP PLEASE

Is it backfiring under acceleration or deceleration? You need that lid on your airbox

Another question to ask is do you have aftermarket exhaust or air filter ?

Are you loosing power too? If so check the solenoid wiring I had that prob on a 2002 500 cat took forever to figure out

When my old beast had a similar issue I ran it the entire winter clearing snow trying to figure out what the problem was...turned out, in my case, it was just the spark plug! Good Luck!

Check your timing chain if the adjuster has no more room to tension the chain you might need a new chain.
Did you leave it sit with gas in it?

That's awesome, but how do you get access to download the manuals?

Just go to the link in top left corner it says free parts and repair manuals. Then look up your year and size

Backfiring is caused by spark getting into the intake through an open valve.....most common cause would be a tight valve. I would suggest setting the valves, and as previously mentioned, the timing chain to see if it is loose and/or jumped.
