2017 Arctic Cat Alterra 500 No Start

Recommended Posts

My son’s 17 Alterra 500 just quit today. It was running fine the started stalling and bogging at half throttle. It finally stalled and will not start. The bike was won in a raffle last year. It had sat for a year before he won it. Has ridden it very little since.  It has 180 km on it. We checked  the plug spark seems strong  disconnected the fuel line at the pump and the fuel pump is working well.  Disconnected the injector and it is spraying fuel.  Air filter is clean and there are no mouse nests in the air intake.  Al fuses checked and good. Ideas?

Only thing I can think of is the timing jumped? Any backfire problems? 
 

Other then that maybe bad gas? 
 

 

Thanks for the quick reply. My son never mentionned any backfiring just that it started bogging at throttle and the finally just died and refused to restart. As far as the gas is concerned it is mostly fresh gas and he used the machine quite a bit a day ago harrowing his driveway and had no issues. I am kind if wondering if a valve is out of spec. Is there anyway to check the timing without pulling shit apart.

Yes it’s just a matter of exposing the cam sprocket and the plug thats on the flywheel to expose the “T” mark. 
But before you get into all that go over the basic shit first like the boot that connects the carb to the engine to make sure there aren’t any cracks, put a new spark plug in just to be sure.  Go over the kill switches to make sure there not flooded with water and it’s an intermittent short.  Make sure it’s good gas and no water got into the tank.

Yeah we are putting in a new plug tommorrow. No carb - fuel injection. No way its water in gas as there has been no rain since it was running fine. I will post again after we try a new plug. I am hoping that is the problem as it does not even try to fire and there is enough fuel going through the injector that it should at least try. Spark seemed decent when tested but who knows.

Right I did read you said it’s fuel injection. Ok well go with a fresh plug and see what happens. Hopefully that’s all it is.

Update. Changed fuel and plug and she fired up. Nothing but premium from  now on. Thanks for all the help. Much appreciated.

Good it was simple. If the machine is going to sit for awhile, I use sta-bil to keep the ethanol from fouling up the machine.

      Working on a bayou 220 that has been ran extremely hard it's whole life. Literally had almost an inch thick dirt/oil covering the motor. Yeah that bad. Surprisingly it runs though. I cleaned the carb and tank multiple times. They're clean enough to eat off of. Readjusted valve lash and set timing. Was about 3 teeth off. It cranks good and runs good only problem is I have to cover the carb intake basically choking the hell out of it for it to start. The com choke works fine. It does this each time I start it regardless of temperature both ambient or motor. Wth? Compression is at 115psi I get 130s if I put a little oil in the piston chamber. Please help. Thanks

      Does anyone know what the 3rd item is behind the battery on this ATV ? I know 1 is the,  solenoid1 is the CDI box, what is the 3rd.

      My Honda Fourtrax won't start. The starter is kicking the engine over, but it won't start. It sat for about a year while I was living away, so I thought it might have been bad gas. I completely drained the fuel, flushed the fuel lines and filled it with fresh gas. However, still nothing. It started and ran fine the last time I used it. Any suggestions on how to diagnose this? It could be fuel or electrical at this point. Is there an easy way to rule one or the other out? Thanks

      I have an older 1980s Suzuki quadrunner red lt 4wd (250)
      so just finished putting it all back together and was running fine just needed to adjust the rebuilt carb
      bf decides to hook up an air chuck to the gas tank because it got a shot of air in the gas line well 120psi didn’t agree with any of the parts including the new carb 
      end result : new battery new carb now it just clicks (one single click) won’t turn over 
      hard to pull start gets hung up (unless I remove the spark plug ) gas flooded out the first time but now does nothing purchases a new starter waiting the arrival 
      could there be damage to the crank shaft or pistons etc? Or install the new starter and try to fire it up ? What caused the starter to die after he flooded everything with gas was working fine. 
      Thank you
