There  is a service manual  for  your  Polaris in the download section . It is in  multi-part pdf  sections .A  quick  glance   at  some of them   on the engine  and carb didn't  show that  hose  , but you might  find it  in a  more thorough read through the complete  manual.  Could it  be  the  impulse  hose  for the  fuel  pump since it ports off the  intake on the engine side of the  carb.  If there  is a separate   pulse  hose from the crankcase , you  could try  blocking that hose off and  see  how the engine runs.  With it  open  the engine would be  running  very  lean. That  looks like   a  90  degree connector  to  join to another  hose   leading possibly to  a vacuum motor  to   operate   something on the  quad.

It has vacuum and runs better when I put my finger over it I think it ties into the vacume line coming from the fuel pump I'm going to try that tomorrow I'll see how that works

Isn't that just a fuel overflow/vent tube?

Can't be .  it  comes off the intake  port of the  block  downstream of the carburettor. It is connected  to the  vacuum  of the intake  manifold .

I have to read better, I thought that was hanging on the bottom under the quad.

      Trying to replace the carburetor on my 2003 Bear Tracker 250. Two brand new carbs in a row from different suppliers.   Both leak fuel out over flow and intake as soon as I turn the gas on. Any ideas. Am I doing something wrong?

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      First of all sorry I have been MIA here for a while, been busy with school and work.  I'll try and reply on some other threads asap, but posting this one because I just picked up a 2017 sportsman 570 before the new year and popped a boot on it going through a mud hole.  The former owner had aftermarket axles on it to accommodate the 4in lift and idk what brand they are but they're skinny as heck and idk what boot to buy to rebuild with?  It's the rear right lower boot (under the brake calp.).  I'll post some pics when I can and sorry again I've missed yall on the forum!
