Oil is getting in the air box from crankcase vent tube, I put the two hoses that go to the air box together then something started to smoke on the front of the engine. There is a filter? In the line I blew that out.

You should put the hoses back to how they are meant to be.

The sump might have too much oil in it, or the oil may have fuel in it, or the engine may need an overhaul. Those are the usual reasons oil gets into the airbox. Your bike may have a PCV valve somewhere, and that maybe clogged and need cleaning.

      Lakota 300 / Bayou 300 crankcase breather tube
      By beast6228
      I've been trying to piece this Lakota 300 back together, slowly. It's been a rabbit hole however. I replace one thing, then it leads to replacing other things. Anyway, When I got this thing I noticed that the hose coming off the camshaft cover wasn't attached to anything, it was just hanging loose. (It's literally just a foot long hose attached to nothing) I figured since it was venting the head it would be ok and I am sure it is.
      However, last night I was looking at the service manual and noticed that it mentioned that this atv has a crankcase breather tube as well. Mine does not have one, so I looked at Partzilla and looked at the parts diagram and sure enough, it's definitely supposed to have one. The problem however is, the service manual does not show how it hooks up and the parts diagram only shows the exploded view of the assembly. I just find that kind of strange, nowhere in the manual does it show how it connects. Does it have it connector, attach to a nipple? It just doesn't say and it bothers me that there is a hole there without anything attached to it.  If anyone has a Bayou 300 or Lakota 300 with an intact breather vent system and could possibly take some clear photos of it or know how it connects I would be very grateful. I have searched high and low and cannot find any information on it.
       
      Thanks

      Moto 4 350 low oil
      By P_syko
      Does the 1987 moto 4 350 have a low oil sensor that kills spark? Or are these too old for that kind of thing?
