some people use atf type f (myself) and others use the 9 dollar a quart two-stroke gear oil you get from cycle gear or whatever. You can use either. Team Green used atf type f so that should mean something....

I 2nd the ATF type F. Works great in 2 stroke trans and cheap enough so you can change it often.

OH GOD,,,

another oil thread...

Elementx665, you are probably not aware, but the subject of oil has been beat to death. It is bordering on a religious argument. There are many old threads that discuss this to no end. I would suggest you search the forum and begin reading through them. You are unlikely to be able to read all the posts and arguments because they are so long.

I used to run exactly what the manufacturer suggested, but was eventually convinced to run ATF. I have good results that work for me with how I ride and how often I change the oil. I buy the cheapest ATF from Wally world, dump in most of 1 quart(bike says 0.875 litre), never look at the window level, and change it frequently. The first couple of changes on ATF was flushing out old dirty stuff, now it comes out looking/smelling new. The clutch response is good with reliable smooth engagement. I ride hare scrambles in the woods with a lot of clutch work. That's what works for me.

The only consensus that you might come close to getting is to change the oil on a regular basis and dont over-tighten the drain plug.

Here is a link to a thread going on for 1.5 years with 231 posts....

Nice looking bike man!! I am also getting ready to change my gear oil on a "new to me" purchased bike. I will probably use the wally world oil as mentioned above and change it out often.

I do have a question though, my bike does not have the spy glass (aftermarket covers) and I have yet to get a manual. Anyone out there have an idea on how much oil to put in a 1995 KX 125?

Thanks in advance

Sweet bike, Ive got an 02 also. After reading the oil thread I opted for type F ATF. I change it every couple hours and am pleased so far.

The oil capacity is on the actual sidecase. Not the clutch cover. It will say something like: .7L or 700ml. Not real sure of the actual cap. but the late mode 85-125 use 700 and the 250's 950ml.

Also I 102nd the ATF type F. My son ran on his stock clutch set for 3 years, 5 top ends, 3 bottom ends, 100 to 103 to 112cc's. He needed a new basket and springs. Even when we sold the bike a a month or so ago, it still mic'd only .001" of wear from new. He has had over 100 races and practiced almost every day it didn't pour down rain or wasn't too cold. Just change it every 8-10 hrs ride time.

Also. somewhere on the right side case, it will say the oil capacity. NOT the clutch cover. It will have .950ml or something similar. Every kawi has it.

BTW, Element, SWEEEET! bike. Man that's clean.

If you notice right below the filler plug, it says .70 L (this is on the 100 though)

For the lazy like me: i second this

I don't do it out of laziness. I feel that the added oil volume will disperse dirt and debris better. It also seems to make my engine a little bit quieter.

With Chokey.

The big bikes (250+) hold 850ml or so. A qt is 946ml. The extra 100 won't hurt anything. Besides, if you fall over on the right side, some will leak out. On the left...fuel will come out. Nature of the beast.

      I have a problem with my stage 2 exhaust cam on my rmz whenever I kick it over the exhaust cam likes to stop at the lift unless I put it at tdc or kick it really slow it runs fine when it starts and I have played around with the shims right now all the valves are shimed and I have checked the timing everything’s to spec it just gets stuck at the exhuast I’m pretty sure it’s something to do with too much compression I probally will end upbuying stock cams but wanted to see if anyone knows how to fix this first

      I recently acquired a 1990 KDX200. The bike runs reasonably well for it's age. The first ride over 30 min the gearbox oil started overflowing into the airbox (overflow hose is routed to airbox). The oil that overflowed and the oil in the gearbox are an odd shade of dark forest green. The oil appeared to be overfilled slightly which explains the overflow. What I don't understand is the weird dark blueish greenish gray color of the oil.  I believe the PO used motul 10w40 ester gearbox oil because he gave me a half used gallon. I use Motul 710 2t oil which is blue, and run green coolant in the radiator. I drained the gearbox oil and there was a nice little clump of dark gray metalic paste on the magnetic drain plug, which should explain the gray hue. What I do not understand is the greenish blue hue. Anyone know what in the heck is going on with this old horse?
      The pic shows a sample of my drained oil. When held up to the light it turns more of a green color. Oil still feels slick as can be.

      will a clutch basket from a 98kx250 fit a 96kx250? How about the carb also?

      I have a new cylinder that i bought to rebuild my 1993 kawasaki kx250 with, because the old cylinder was destroyed. The guy said the cylinder is overbored a little but never gave us numbers. The new one i bought came with a piston thats been used and i would like to replace. I believe the piston that came with the cylinder is the correct size, but it very well could be off and i have no way of knowing. So how do i properly measure the cylinder bore, and how do i use this measurement to find what size piston I need to get?
       
      thanks,
      Kaelan
