regular straight weight motor oil... non-low E... it will say right on the back, look fo rthe SAE circle, if it says energy conserving, it's low e..
use a straight 30,40 or 50W

ATF works really good with a wet clutch...You'll get very good feel at the lever with it and your bike will feel like it revs quicker due to the reduced drag from the thin oil...However, you need to change at least every other ride...ATF is designed to lubricate the transmission while allowing clutch plates to grab effectively...
If you don't feel comfortable with ATF, just go with a regular petroleum oil that is missing the words "energy conserving" in the circular api label....10W30 weight and lower are usually the ones that are in the energy concerving category..10W40 and above are usually fine but make sure to always look at the label....Straight 30W is probably the best choice of regular petroleum oils.

ATF is great for the clutch but motor oil is better for the tranny. I would rather replace a clutch than a tranny. I currently use Mobil 1 15-50, the red capped bottle. My bike shifts like butter...real nice! I previously used Honda tranny fluid, the stuff in the red bullet shaped bottle. Worked fine but I like the Mobil 1 better. ;)

I've never been real satistied with the friction material Suzy uses for their plates...will glaze over when they've gotten hot, and when using 10w40 I have to take them out and de-glaze every other ride (drags and causes stalls in tight woods) ATF type F works real well to avoid this, but yes... it's not so great for the tranny gears. I've had good luck mixing 400cc of ATF and 300cc of straight 30 or 40w (depending on summer/winter.) Change every-other ride. For my 03, I've heard KX250 plates bolt right in.
New to 2 strokes. BY tranny oil, do you mean that plastic screw type oil plug on the side of my 82 CR250R is NOT to lube the bottom end of my motor? Like it doesnt use a OIL pump to pump oil to my crank, and rod bearings? Sorry if I seem like an idiot, as I am just learning things that are 2 stroke. I learn fast and I dont forget. I also dont give advice uneducated either, so if I dont know.. well I wont claim to. I have been using Castrol GTX motor oil on mine. Clutch seemed ok. If 10 w 30 isnt what I should be using.. what should I buy?

That plastic screw type oil plug you're talking about is where you put in transmission oils. It will lube your transmission and clutch.

05 RM250, and ive run valvoline 10/40 for a whole year of racing or practising nearly every weekend with no probs, the clutch is still well within spec. I ride a lot of sand and i really abuse the clutch.
But, i replaced 3 of the springs with the stronger barnett ones.

Good then I am not crazy after all. I was looking at all that stuff when I had the side engine cover off fixing the shifting fork trying to figure out how that oil was going to get to the rod bearings. LOL. My Brother has an FL250 with NO oil pan..LOL we are both new to 2 strokes and were scratching our heads..
So is Castrol GTX ok for my bike. I dont seem to have any clutch problem...

ATF is a high pressure lube that is fine in a tranny. It is what is spec'd for the transfer case in my Bronco.....pleanty of high pressure gears there when pulling in 4 low. No bike would ever develop gear pressures that come close. The gears will do fine so long as the ATF is kept clean.

I like the Mobil 1 15w 50 as well. I think its called Extended Performance now. Easy to find at Wal Mart or Auto Zone . . .

type F here, or dexron if theres no F laying around
I know the question is about non-2 stroke specific gear oil, but why don't any of you guys use the 2-stroke specific gear oil? Is it just a cost issue? I've always used the high buck stuff from Golden Spectro and Bel-Ray. Works great.....fluid always comes out nice and clean, and shifting is perfect.

IMO since theres no filtering it is more important to get the old oil out than to run some high tone expensive oil and hope it will hold up longer.
Theres nothing out of the ordinary going on in these gearboxes. To me it doesnt warrant using "special" oil that probably isnt that special anyhow.

Well, I see it as a comparison more like to a manual tranny in a car. The only difference is clutch particle contamination. Neither have filters, but you go 15k+ miles on the car's tranny. Both have bearings, both have gears. A car's tranny benefits in the long run with a quality synthetic fluid, whether it's a Ford T5 running ATF or a japanese car's manual tranny running GL-4....they always shift better and have reduced friction from the use of high dollar synthetic fluids.
I guess it's really just a cost thing. I just don't want to be doing something wrong by putting high end stuff in my tranny. I know it may not do much over any regular motor oil or ATF (especially in short change intervals), I just sleep better at night with high end stuff in there......mainly because I'm as anal as it gets with my toys. :fft:

Thanks for the help. I put Castrol GTX in it and called the dealership. They freaked out. put i only ran it for 5 minutes and only shifted up to 5th and back once. But I got it out and put in Belray 80w. I think im just panicing though but the tranny sounds louder now. I guess i never noticed it before because i was to busy in the break-in (holding on) to notice. But the 125 made the same noise and i ran the 80w in it. But I guess im just panicing because i still owe money on it.

I have my factory 03 RM250 manual in front of me and it says:::
SAE 10W30 for transmission fluid.....
So in goes the low E motor oil....
I would rather change my oil 8 times and spend $8 doing all that instead of once at $8.00....
80W is a hypoid type fluid and is really thick... i tried it in my 125 and hated it, shifted like poopoo.....
Go buy a case of quaker state straight 30 or 40 and be happy...Then tell the dealer to suck it...

You used the wrong gear oil!
Don't use 80W Hypo; thats for differentials! That would make it worse! You want 80W 2-stroke Transmission oil; which by the way is about like 30W motor oil. At least on Bel Ray it will be marked as 2-stroke transmission oil. If it says the 80W Hypo gear oil; thats the wrong one!
