kx85 tranny fluid? and leak?
« on: February 09, 2012, 02:09:14 AM »
hey guys quick questions, what is good for tranny fluid in my 2002 kx85?


and also, my airscrew needle has a sllight leak out of it... like dirt gathers there because of fuel buildup (very small amount) do i need a new needle or what could be causing ths?

thanks!!!

I'm not sure about the fuel issue with the needle, but I think that SX Clutch saver is one of the best tranny oils out there for two strokes.

I was told by my motorsports store NOT to use that stuff. I was for a few changes and then the guys was like 'why do you buy oil when you have a two stroke?' and I said I used it as my tranny oil. He said it doesn't properly oil the clutch, but I'm not sure on that one. Four strokes use it, and the clutch is the same. I would do some research on that. But as for me, I will stick to my SX clutch saver.

that oil isn't good for that kind or engine. the oil will suit a road car engine were high rpm aren't reached.

that would work in you gearbox like water and the clutch would slip all the time.

try some 80w90 or 75w90 from a good brand, like maxima, lucas oil, belray, etc

Because 4 stroke oil has to deal with combustion contaminant's while gearbox oil does not.
Also gearbox oil has a higher shear rating which is better for your gearbox.
You would not put 80w90 into a engine so you shouldn't put 15w40 into your gearbox.

When you ask questions about tranny fluid you are going to get 1,000 different opinions...  I run AFT (Automatic Tranny Fluid)  I've been running that since the 70's (yes I'm an old fart) without any issues.  I change it often as its cheap and easy to change. Everyone has an opion, and they are all like ripe onions, (they all stink)   :D

As far as the leak.  turn the screw in can count the turns.  Then remove the screw, clean everything, and ispect to see if an o-ring may be missing or damaged.  Check with an on-line parts diagram to see if there in an o-ring or somethng causing the leak.

 I've ran 10w40 in every bike, trike and quad Ive ever owned with zero issues . I think its pretty much all in personal preference .

Run what you want.
It doesn't really matter.

Twostroke power asked the question.

  It probably will  :P Everyone has a different opinion. Just what ever you use, change it every 7-10 hours. Know matter what you use, as long as you change it that often, it shouldn't matter, as long as you don't put acid or something in  :<img src=" title="Roll Eyes" class="smiley">
