Hi all, I recently picked up a 99 Xplorer 400 4x4 for a few hundred bucks due to the amount of work it needs. Overall it seems to be in good shape with nothing bent, minimal rust, plastics are good, etc. The main issue is that it won't go into gear. I've read on here and other forums about the multiple reasons that can happen and have a list going of things to start looking into. There are a few things about this model that I'm not clear on and searching the forums and repair manuals haven't cleared it up for me.
#1 - I don't see a radiator or fan. I have seen some references to the 400 and the 400L. Am I right in assuming that the 400L is Liquid Cooled and the 400 is Air Cooled? If correct and mine is Air Cooled, am I missing a fan? I do see a two wire plug hanging from the top near where I would expect a fan to be located.
#2 - The air vent tube going into the clutch is very lose and I've seen where there is a coupler in the manual and I'll see if I can find that part. The other end of that air vent just curves down and is open. That seems like it has the potential to let in a lot of dirt/dust. Is there supposed to be some sort of air filter there?
#3 - The engine fires up immediately and runs strong. I have noticed that I get a few large drops of oil right under where the exhaust pipe connects to the exhaust manifold. I've only had 4 stroke ATVs in the past. Is this typical of a 2 stroke?
#4 - At the front of the engine I see a hole that looks like where a radiator hose or maybe an air filter might connect. I attached a picture of it. What am I missing there? Maybe my engine is liquid cooled and a previous owner removed the whole system?
