i got a 2011 yard sport ys 400 and it 's loading up I had the carb off and cleaned it no it loads up don't  know which way to turn the air idle screw to lean it out   

HELP

So I assume it's running rich, which is to much fuel, not enough air.so I would turn the air idle screw out a little bit to lean it.if not, I would call the manufacturer and ask them.

Did you solve the issue? I have a 2012 ys400 and it's doing exactly what you described. I can't find any helpful information online for this thing.

      My buddy has a ut400 that the forward gear keeps popping out of gear. She only has like 400 miles on the odometer .the shift cable has been adjusted and the shift lever has been updated / modified. All other gears are good. Is there an internal detent cam or something that wears out or shift fork that can be replaced ? Or is there some other magic that I can perform ? Looks like the engine needs to be split.

      When we first heard the noise, we immediately stopped driving it...at first we thought it might be a linkage issue, but after further inspection looks like the sound/jolting is coming from the rear diff. Took a video below...
      Anyone know what is creating the diff to skip/jump like this? We drained the diff oil and didn't look terrible, no metal.
      Other info that may be useful:
      1400 miles on it
      Recently tightened the E brake
      P.s. never posted on this forum before, let me know if the video does not work

      Have a Coleman UTV 400 that cranks, runs, drives well until it gets warm and is put under load.  Light throttle or full throttle it doesn't bog, but it will cut out mid throttle if you move the pedal quicker than it seems to like for example when you're getting ready to go up a hill, but if you immediately floor it, it will do just fine and not cut out.  It's random if and when it's going to do it, but is consistent in that it happens only when hot/full operating temperature.  I've replaced the injector twice, same with the spark plug and tried different heat ranges (NGK 7,8 and 8 iridium), replaced the fuel pump, adjusted the valves, checked air filter which is like new, changed the oil, replaced the fuel filter.  No check engine light.  I don't have a code reader for this.  Initially I thought it might have a head or head gasket issue as when I got it, the oil was over full, very runny like water milky and it was smoking.  I've changed the oil since then twice to clear and clean everything out, and it seems to be good.  Coolant stays the same level and so does oil with no changes in consistency or need for adding more. Had I think 7-9 miles when I got it and now has about 77.  What should I try or consider next?

      Is there a better performing higher volume injector than what they come with or what is the best replacement for the original?

      Is there a diagram of all of the grease zerks for a Coleman UT 400?  Mine squeaks like crazy and want to try and remedy it.
