Post by: IcemanK5 on May 11, 2009, 09:20:52 AM

Did some hunting threw some old threads here and could not find a answer.

I usually just dump a quart of ATF type F in and call it good.

Are you serious about using a full quart? Sorry if I missed the sarcasm or if it is actually a good idea.

Not any harm in it.  I always run my gearboxes with more than the alloted oil quantity. I am a more is better type. Cam.

Naw, I'm serious.  That's all I do, drop a quart in and ride.  I change after every other ride also.  It's not too bad, seeing how that type F is fairly cheap.

Thats a good theory, but what about foaming with excess oil levels? Thats always a legit concern I think.

I can't see foaming being an issue in a dirt bike trans. Dirt bike trans (2-stroke) are not pressurized with oil and for the most part almost submerge in oil. Foaming can occur in auto engines due to an increased oil level which allows the crankshafts counter weights to whip the top layer of the oil and churns it into a froth. Aerated/pressurized oil will not lube the plain bearings found in four stroke engines.

You'll love the ATF type f in the gear box. Better shifting and clutch action.

Good, You change your gear oil every-other ride? Your just wasting money and oil in my opinion. What does it look like when you drain it? Probably no different than new.

Yeah, it comes out pretty dark every time...  Lately it hasn't been as dark, but the bike had been used and abused before I got it... hence all the problems I'm having now. :oops:

I'd really like to dump this frame and do a Stewart rebuild and an AF conversion (or modern 450 quad conversion) but it's out of my budget right now... :lol:  Eventually...

Do you have steel clutch drive plates? The alumn drive plate will dirty the oil after one or two rides. I 've used the ATF for max of four rides with steel plates and the oil comes out just about the same red color as new.
