KDX200 Gear Oil???

[Peter]

Hi,

Thanks to everyone who responded to my previous post about me getting
a new '02 KDX200!!! Now, I have one and I am wondering what gear oil
I should use in it (?). The manual says 10w40 motor oil, but I'm
wondering what long time KDX fans use (?). If this is the best route,
I am thinking of using Valv. Durablend (part synthetic). Does anyone
have any suggestions? I want to make this bike last as long as
possible!!!

Thanks again,

Peter :)

Use Type F automatic transmission fluid and change it every few rides.
Better to use an inexpensive oil and change it frequently than get 6
dollar a quart stuff and change it infrequently.

My 89 KDX200 trans never had a problem over the course of the 4 years
I owned the bike using Type F changed every 2 or 3 rides.

Isn't ATF basically hydraulic pump fluid with some lubricating
properties rather than a lubricant per se? Despite your apparent
success with using ATF in place of lubricating oil I am skeptical of
this substitution. Where does this idea come from?

Hello!
I have a KX250 and I use Automatic Tranny Fluid Type F. Gotta be Type
F, tho! It'll do great in your gear box and you will love your
clutch. There's a dude called JokerKX that checks out the group and
he suggested it to me a couple-o years ago - I've used it and dug it
ever since!

I just wait for a place like Kragen auto supply or where ever to have
a sale and I buy a case - usually for about .79 a bottle, and then
change the fluid every 3 rides or so.,

Hope this helps..

It has a lot of shear-strength and popularity on RMD - this is a commonly
repeating thread that;'s beena round here since as long as I can remember

I've been using it in my KTM300 since the beginning. Some people say use only
Type-F (Ford) and others have had luck with Dextron (GM). I get type-F at
NAPA for cheap and change it often and it seems to work as well as specially
priced moto-oil.

It's been used for years in motorcycle gearboxes with great success.
It is often used in some bikes to correct notchy shifting as it is
relatively light in viscosity.

If you think about it, ATF is specifically designed to lubricate gears
and wet clutches in transmissions under fairly high horsepower and
thermal loadings. Sounds like a motorcycle gearbox to me.

Some ATF (Dextron?) has a little bit of slip engineered into it to
smooth out shifting. The recommendation for Type F is to use a product
without the slippery additive.

All that said, I prefer to use motor oil corresponding to the bike
manufacturer's specified API grade or better. Actually, I use Mobil 1,
15-40 synthetic.

I use Belray Gearsaver and use 1 full quart. Jump over to the JustKdx
forum on dirtrider.net for this question. It makes the bike shift
nicer and quiets the KD X down. I also like the color..
