I don't know if it's a common problem or just me, but you might want to check the hose clamps on your rear diff vent.

Mine was leaking oil up around the bellows/accordian, and I noticed the clamps were loose.

Upon further inspection, I found that not only the two connecting the bellows to the hose were loose, but the clamp at the diff vent to the hose was loose too.

Freely spinning clamps can't be doing too much clamping.

I replaced all 3 clamps with some better ones that actually clamp (from O'Reilly). I also went ahead and replaced the splice joint from the hose to the bellows with a slightly bigger one.

I drained and filled the diff after that to be safe. The front is next...

      Check your dealer for new tires..
      By rjsummer
      Just some friendly advice on new tires. Check with your ATV dealer. 
      There are so many aftermarket sites, Revco, Royal Distributing, Partzilla, and on and on. Even with their “ big sales”, my local Canam dealer’s REGULAR price beat the tire prices of the 3rd party sellers! People often assume the Dealership will cost them more, but I found this not to be true!

      Leaking valve seals?
      By LCP92
      Guys, I've got a 1999 Honda Foreman 450S.  It runs great, but smokes out the exhaust after startup until it warms up.  I'm thinking the valve seals are leaking.  I was wondering if there is a way to replace them without removing the head or if there's an oil additive that will recondition the rubber seals.  Any advice?

      2023 Hisun Axis 700 fuel problem
      By ButchM
      Hisun 700 EFI. Replaced TMAP sensor had broken off . Fuel pump pressure 41psi. The only way I can keep it running (and runs fine) is to close off fuel return line.

      Has anyone found aftermarket CDI for Big Bear 400?
      By Callaway
      I am trying to diagnose a no spark issue with my 02 Big Bear 400 and I am really hoping it is not a CDI.  I have done the test on the stator and I believe that is faulty.  I ordered a new aftermarket one from a the jungle website and it tested bad right out of the box so I am waiting for a different one to arrive from an ATV parts supplier.  I started looking out of curiosity at CDI units and it seems if it is for a big bear you are SOL.  Kodiaks, no problem.  Big Bear. No such luck.

      This thing came with a cheap aftermarket carb on it the problem I'm having is it won't start with choke installed into carburetor it will start and get run without it installed then bogs out after about 2 min run time I've checked timing , compression, checked valves for proper clearance , also did a smoke test for air leaks found none.
