'03 trx90 engine question

What is the hose for that goes from a nipple on the top of the crankcase to the bottom of the air breather? I have a steady stream of oil going thru it, that is flooding my air breather with oil.

i would have thot an overflow tube, but i don't know for sure. do you have too much oil in crankcase? this might be better posted in the kids quads section. people there know these quads and are very helpful.

sounds like the positive crank ventalation tube... if you are burning oil this would explain the air filter...hope this helps...of course you have a bigger problem now...
