Sled backfiring

[2008 Nytro RTX]

Went to start my sled today after trying to start it a few time its didn't run right and back fired when I gave it gas. Could it be gas from last season just messing it up? I think taking the old gas out and some fresh gas with some injector cleaner it should be fine,Am I right?

I had this happen to me. after the deal did some warranty work i got it back and it was doing it. i came to the conclusion they didnt wait for the red warm up light to go off and it loaded up. i put new plugs in and its been fine ever since.

Ouch,Isn't changing the plugs a very hard? I NEVER changed a plug on these things in my life

Try some seafoam and see what happens. Did you have anything apart on the sled that might have been reassembled incorrectly?

Nothing that would make it backfire and not run right,If I was a betting man I would say its the stale gas in the tank.

NO, jsut be careful when disconnecting the coils/plug boots, twist and pull them out. Make sure to use a spark plug socket, and hand thread the plugs then snug them up with a rachet.

try some seamfoam injection cleaner first, if thats not it i would try plugs next. they are easy to do.

like Stop said, careful pulling the boots off but once they are i put plug socket on an extension and put it down in the hole, then you should be able to attach the ratchet to it.

Did you let it warm up ? Mines always a little bitchy cold

I have the sled for almost 3 years and it never did this,It was hard starting then it ran like #*$&@. I truly hope its not the E-10 fuel fucking with my motor AKA BANG O. So out comes that gas in goes fresh with sea foam and maybe if that doesn't work some fresh plugs. Should I put the Sea foam in with the fresh or the old gas?

The fresh.

Wouldn't hurt to change plugs anyway

Plugs are relatively easy to change. How about finding non oxygenated gas (no ethanol) not only for the riding season, but especially for the off season with storage in mind. I am a strong advocate of sea foam as well.

Would anyone happen to have a write up on how to change the plugs on these things? One thing I miss about the old two smokes,Pop the hood and in 4 mins you had your plugs out and in
