I have a 2000 polaris trailboss and am trying to find out where to drain the old oil out...Any information would help..thanks

 

There is a bolt on the bottom side of the gearcase that is jammed against the frame.run the in and take the bolt that is screws into out of the grearcase.

 

Hey man thanks a lot, i found the drain plug and changed it out. However,
Does anyone know of any other fluids that may need to be changed on my atv? Besides the Oil, tranny oil, and brake fluid? Are these the only three on my atv? My atv begins to make a small noise around 20mph..It only makes it when you hit the gas tho...If i am going 30-40 mph and then let off the gas, it will not make the noise as it is rolling and slowing down, but if i hit the gas again it will begin to make it again..Im not sure if it is something that is low on fluid, or something is just rubbing as i hit the gas at these speeds.. Any help is appreciated, thanks

 

Sounds like the chain rubbing the guide

 

well i was thinking it was possibly the chain guide also, but i took it completely off and rode and it still makes the noise..

 

how do the sprockets look
