any of the major brands are good, just make sure its for ATVs ... otherwise it will damage your transmission ... synthetic is better and you dont have to change as often ...

Use rotella 15w 40 diesel oil in that air cooled Honda

It's all I ever use in my 400ex and almost every other 400ex owner uses

      It will not turn over with starter and will not fire while pulling pull start.
       
      The only thing that Ive tested that didnt test correct is the kill switch I read on another forum to test black and Black/white wire for continuity when in off position I did and it shows continuity like it should. Then when you slide it to run it should be open and show no continuity which mine still shows it while in the run position. So I unplugged the CDI just for sakes of doing it and the kill switch then tests correct. So where should I test next without unplugging CDI?

      I can't for the life of me find the correct service manual for this unit. It's air cooled, not liquid (oil cooler tho) and every manual I find has the wrong front differential diagram (it does NOT have a 2wd/4wd shifter).
      I'd be eternally grateful if someone could point me in the right direction. I can probably slog it out from some of the exploded diagrams I've found, but a good "do this, do NOT do that" manual would be a godsend.
      Regards,

      Hey guys, Thanks for looking at my post. I haven't had a lot of experience with problems like this before, so I'm a little bit at a loss. The Quad was really hard to shift, (the dirty carb leaking gas making it idle high didn't help either). The only Idea I have would be is that the torsion spring is worn out, and that there is a normal parameter for how much it should move when those two arms of the shift shaft assembly spread apart.  That's my thought. Maybe someone who has more knowledge then me can let me know if i'm on the right track 😀
