Hi all, total new guy here. Just picked up a 1999 Fourtrax 300 4×4 in trade for an old boat I had laying around not being used. I was told the motor smoked but the machine ran and drove great, and also needed a starter. After replacing the starter, the motor fired right up, idles great, has excellent power, and will do a wheelie with my 225 pounds on it, but smokes like a fog machine. I mean its pretty bad. It burned 2 quarts of oil in the two hours I rode it on day one (never let it run dry, kept topping it off).

I’m assuming that this thing needs at a minimum a top end gasket kit, rings, and a hone. Possibly bored and oversized piston job too. Question is is it even possible for this thing to burn that much oil that fast? Or am I looking at more problems? Not a lot of money going around to throw at this thing right now.

Oh also must mention, although this is my first atv, and I’ve never worked on this type of engine before, I am a professional ASE certified auto mechanic for a living, so I’m not afraid to get my hands dirty.
