what oil should be in a HONDA TRX 400 EX

Recommended Posts



I'm assuming since you're asking, you don't have an owners manual?

i use havoline 10w-40 in mine but any motorcycle oil will get the job done.

JUST DONT use synthetic oil with MOLY in it, this will make your clutch slip.

honda 10w/40 because ur cluthes also works off ur motor oil as well / castrol and other oils will fill in the pours in your cluthes and cause slipage i found out the hard way after 7 setts in one year.

      Recently purchased a 2007 Suzuki LTZ250 for my kids. I am having a difficult time finding service manual for this quad. I want the kids to study it before they ride it. Suggestions?

      I haven't rode in a very long time and a friend is selling me a 1985 TRX he obtained through family that is in pristine condition. I have a few questions since he can't find the manual- and sorry if I come off dumb or "noobish".
      1) Gears- these are 5 speed right? 5 down and up is back to neutral?
      2) 4 stroke 10-w30 for oil? How much?
      3) spark gap?
      Thanks for your time.

      I forgot to mention in my first post but it also came with a mid mount snow plow which I have removed for the time being.  I mainly bought to use as a work machine, plowing snow and hauling wood that I have cut from back in my 10 acre woods.  Maybe haul a mid range log or two also so this won't be for show or trail riding.  I might add a winch also for snow and wood hauling.

      when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out 
       
      Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes)
      When i try to pull start (push start/roll start) it made a not normal sound  and wouldnt stay running.
      If my bottom end is blow why would it still turn over fine,
      Are my valves siezed or not working properly 
      or is my timing off causeing valves to not open in correct order with fire 
      PLEASE HELP all help is appreciated
