I have had the 2000 400ex for a few months now. I have changed the oil on my own and know that I have no leaks. I noticed it smokes when my daughter gets on it and revs it up through the gears. My friend also noticed it puff a few times while we were riding. I left yesterday with a full oil res and we rode 1/2 the day and I have an almost empty oil res now. So I guess I have an oil burner. What are the suggestions for repair?? I am the third owner of the quad, I know it needs a rejet and valve adjustment, but think I have a bigger problem now.It runs strong, no problem there but I am loosing oil! I had planned on replacing all the seals and gaskets for the engine first but what should I do first?? New rings, etc for piston, or do I need a new sleve etc?? I do not want to change the bore at all but keep that stock. Any help is appreciated.
