I do not know what type of transmission oil to put in my 1994 suzuki RM 250. I just got it and it would help if i knew how much to put in to. Can you Help me?

Your transmission uses less than a quart of oil. The exact amount of oil is stamped by the fill hole on the engine case or side cover, probably about 800cc or 900cc. If you choose automobile oil, do not use an oil with a rating greater than SE, SF, or SG. You could also use motorcycle gear oil like Belray 70 wt, 75wt, or 80wt. Or you canuse any oil that has the JASO MA Japanese engine motorcycle rating for engines that have wet clutches and transmission gears running in them. Do not use any oil that says "Energy Conserving" on the label.

use the correct poss ion to fut fork oil........ and you should be drain new oil and them drain off the old oil

motul 5100 5-40

You can use 10W 40 motor oil.
I've seen some people put Lucas oil in them.

If you have the stock valving, I would run 2.5w Motorex in the damper to compensate for the stiff feel stock, and thicker oil in the spring chamber such as Mobil1 5w20 to allow the oil lock ring to do its job on bottom-outs. I'm at 375ml in the spring chamber and I weight 155lb.

The engine doesn't use oil,the only oil it gets is from the 2 cycle oil mix in the gas,the transmission uses 85\90 transmission oil such as bel-ray or others. I would NOT reccomend running 10\40 in the trans...

Fill until the oil dip stick indicates proper level ... no more and no less.

Castrol Syntec motorcycle 10-40wt is what i woul recommend and you have a dipstick. So if you have drained the old fluid start by pouring in 1 qt. then check the dipstick w/ bike level on level ground. Then add a little oil at a time until full..If you have a sightglass instead of a dipstick then fill half to 3/4 up the sightglass. Buy 2qts while your at the store...good Luck to you friend...Tim

Other problem sounds like carb or air filter. Does it spit back through carb ?

use decent two-stroke oil at 50 to 1. don't ever buy oil from a gas station without sealed container; who knows what the oil really is
