Specifically use "two stroke gear oil".
Personally I use Castrol MTX Gear Oil, SAE 75W-80. My bikes are an '84 Yamaha IT250 and a '01 YZ250. I have had no issues with clutch bind or sticking and change oil every 12-15 riding hours or 6 months. There are many highly rated specific 2-stroke gear oils, go for one that is readily available in a variety of places as it is wise to stay with one oil.
In general, cheap oils are pointless and Brand names (BMW, SUZUKI Oil etc.) are re-blended common oils. Bel-Ray, Castrol, Amsoil etc are much the same and are all excellent. Cheers!

Cant get out of gear

If this is a Suzuki RM250, But even if it is not, this is where I believe your problem is.

Start simple. I'm willing to bet that the shifting mechanism behind the clutch basket is broken in some way. And that your actual transmission including the shift forks, are fine.

I personally have broken item # 26 and 20 on my '02 RM250. Both cause the same problems that you have describe. and both can be repaired by leaving the engine in the frame, but pulling the large clutch cover and the clutch basket. Everything sits halfway behind the lower left part of the clutch basket.

Let me know, as the title of your problem was very limited on bike, year and of course more symptoms. Thanks Mike

I have 95 suzuki rm 250 and it will not go into 5th gear...i bought it off of craigslist and i didnt get to go very fast on it.I brought it home and went to open it up and it just stops at 4th gear. The...

Both the 1995 and the 2003 RM250's have 5 speed transmissions. You will have to split the cases to see why the machine will not shift into fifth gear. You probably have a bent shift fork, an nick in the shift drum, or a damaged gear interlocking pins.

My rm250 smokes like crazy until all the transmission fluid is burnt up. i just totally rebuilt it and dont know why this is happening

hi,if your bike is burning the trans fluid,it sounds like one of the seals has not seated properly allowing trans fluid to enter the bottom of the intake/combustion chamber,i am afraid to say it but you will need to pull it apart again and investigate...cheers

Got a rm250 1999 its keeps jumping out of secon gear wen the power ban kicks in

Unfortunately, this most likely means that you've got worn or damaged parts inside the transmission - which also means that the engine has to be removed and disassembled.
With the transmission parts removed, check for rounded edges on the gear "dogs". Having straight edges on the dogs is what keeps the gears from sliding apart and the transmission from jumping out of gear when power is applied.
Also check the shift forks for wear and straightness. When your transmission jumps out of gear, excess force is applied to the shift forks, causing wear and sometimes bending.

Can i drain the transmission fluid on a 05 suzuki forenza my self?

yes. HOWEVER, whe you refill it. make sure that you put in the correct type of oil. refer to your owner manual prior to putting in any old automatice trranny fluid as some tranny's require a sopecial type of oil, put in the wrong one and you fry your transmission. If its a standard, put in the correct weight of gear oil. Not trying to scare you, but i want to make sure that your REFER TO YOUR OWNERS MANUAL for the correct type of oil to put in after you drain it.

good luck.
