Two-stroke trans oil

[Lion]

What are you guys running using for trans oil? I have also been told that you can run automatic trans fluid as it is virtually the same product?

[Buddy L]

Just 2 stroke grear box oil seems to do alright for me (motul):mellow:

[Lion]

Sorry, I should have rephrased my original question. Are there any prefered brands of gearbox oil out there?

[GR81]

i bet cheese told you that! lol

i use Motul

[CM2005]

i used 10/40 car... :shutup:

[crazybigal]

i use plain old mineral dextron auto trans fluid in my gas gas, goes fine but i change it regularly

[Lion]

Yea cheese did tell me lol. I think I'm better play it safe and just buy the proper oil

[cheese]

booooom told me to run ATF as its teh same shit. Alot of people use it. ONly use it on 2 smokers though!!

I actually only every ran motul in teh gear box and on teh last fill I got some stuff from MX dad (plutoline)

[B0000M]

ive used atf for like 13 years, always been mint

[Danger]

I only use ATF, 5 litres of Dexron III is cheap as at Repco. Cheap enough to replace it every second ride. Makes the clutch and gear box work very smooth.

[Lion]

Sweet as. Will give the atf a try.

[cheese]

Bloody motul pimps!

[GR81]

Bloody motul pimps!
i prefer general pimp!

Any quality 2 stroke trans oil will work, have only ever once had a problem and that was with elf oil in a KTM360sx.
Run ATF in my TM, doubt it'sthe same as it's a lot runnier than trans oil but never had a problem, If you are going with ATF change it every time, same goes for any oil in an MX bike really. There isn't much in there and it's cheaper than gearboxes.

wouldn't be to put in the a100 you bought off me by chance would it john? lol

[Lion]

Nah I used some old motor oil in that. Wouldn't happen to have a spare tank would ya? My mate crashed it and now the tank is fucked.

[Rupe]

So is it ok to use ATF? or is it best just to buy the proper stuff?

[Danger]

Dexron III ATF is all I ever use. Change it every 2-3 rides.

does it depend on how long the ride is?. i only take my bike out occasionally for half an hour at a time. thanks

[crazybigal]

what he was sayn is atf is so cheap and the bike only takes a Litre so you may as well change it more often, but you will be fine changing it every now and then.
i drouned my bike and had to drain the fluid, came out like pink goo:rolleyes:

[cheese]

I think that every 10 hours is the general rule.

[Lion]

sweet will go buy some tomorow thanks

[Danger]

Yeah Cheese has got it about right. I try to change mine every 2nd ride and I usually ride about 3-4 hours at a time. But if after two rides the bike is not dirty enough to wash (like sometimes after those Woodhill rides the bike is still pretty clean) but still a little too dirty to work on, I'll stretch it to three rides and change the oil and bleed the brakes after cleaning the bike. Makes it easier and less chance of contamination working on a clean bike.
So two rides minimum, 3 rides maximum between oil changes when using ATF is my rule of thumb.:niceone:

[cheese]

You bleed your brakes as well? Gosh!

Um still waiting on my tax refund greg I'll bring all my suspension in for you to service.

[Danger]

Sweet as. Yeah my rear brakes get really hot and the brake fluid deteriotes quickly. To ensure maximum braking performance I find it best to bleed them after cleaning the bike and at the same intervals as the gearbox, if not sooner if they have had alot of abuse.
Use dot5.1, not dot5.

Danger, Didn't you say one of your bikes was out because of a bit of the gearbox that fell out. I'm not so sure about the ATF.

I use Motul (only because I get it wholesale through a mate) and change it every 10 hours.
When we raced karts we always used proper gearbox oil, Castrol or Rock in those days. Changed it only twice a season. Our 125's where doing over 12,000 revs, on methenol, had 50 times as many gear changes per lap as you guys, had no clutch, clutch baskets, plates or springs. Removed them for more power! We'd pull it through gears under full power on occasion and mostly with just a flick off the throttle then change quickly back down 4 gears on 3 metres. Never blew a gearbox.

[k14]

I use shell advance synthetic. Never had any problems in the rs and it needs to be fairly high performance. Change it every 3 meetings usually. Not too hard on the pocket either, about $17 per litre iirc.

Yes, a bit of tooth out of the g/box or some drive part on the 200. But this is an 02 bike with a lot of very hard miles on it and its the first g/box problem I've had. Not sure what it is because I have not had a chance to pull it down yet.
FWIW my mate AJ has done his gbox on his 07 200 recently (dead toad), also did the same thing on his 06. Not sure what oil he uses, but I know its not ATF. So I think my gbox life has been very good.

ATF is proper gearbox oil.

[cheese]

I was about to say its because its a suzi then I find it the KTM that did it!!! OMG!

[Lion]

i put some castrol atf fluid in my gbox today and am very impressed. it makes the gearbox work very smoothly. good shit

[Danger]

It will be even smoother after your next oil change.:clap:

[B0000M]

right, ill settle it.

ATF is good. ATF is cheap

ive used ATF in CR's since 1994. between 1994 & 2001 i raced seriously & heavyly. to this day, i have not had a CR fail on me.
