Sportsman 90 bogging down

Recommended Posts

Have a 2000 Sportsman 90 I picked up for my youngest son. It had been sitting and would not start, so I pulled and cleaned the carb, cleaned the tank, put fresh gas in it and it fired right up. It seems to run out good, but after riding it for a few minutes when you de-cellerate it bogs down and will slowly stall out or drop down to a low idle.

I can fire it back up and it will pick up ok, but every few minutes it seems to want to bog down and throttle response is non-existant. Fuel and plug are fresh.

It does seem to be pretty smoky with the auto oil injection. Could to much oil cause this type of behavior ? Anything else to check?

Thanks

Check your gas tank vent, might be plugged. Does it suck in air when you loosen the gas tank cap after it stalls out? Just a thought.

      I have a 1997 Polaris Sportsman 500 4x4 that recently started bogging. Was riding down a road and all of a sudden started bogging. I tore the carburetor off, cleaned the jets , checked if there was spark. I'm pretty much out of ideas. After cleaning the carburetor, put it back on an now it wont start. Any ideas?

      I am having an issue where it sounds like the gears are slipping if I hit the throttle really hard and also after letting off when the engine brake is applied. Also, the drive train that goes to the front also rides again the gear shift box. I will attach pictures and a video here shortly.
      Thanks in advance!
