Sportsman 90 bogging down

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

      Where you like to ride and what riding does for you?

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      2000 Honda 400EX Backfires
      By Trent Finnessey
      I’ve got a 2000 400ex with a dg slip on muffler, it came with he stock muffler on it but the previous owner had the dg in a box so I put it on. I’ve been riding it for the past month and a half and every time I let off it backfires, and the other day the backfires got way louder, 2x louder! I’m concerned that I may hurt my motor? Why does is backfire??? Thanks

      2000 Grizzly 600.
      By Randomnumber73
      I'm working on my uncles grizzly and it sparks once on initial cranking then no more after that. If I let off the start button then press the start button again it will spark once then stop sparking. I was wondering if anyone seen this issue before.  Also I've never used forums before so sorry if this question is in the wrong location.

      '03 Honda Sporttrax 400EX Carb issue.
      By Dumass
      My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area. 
      Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.
