It's been a long time since I've worked on a two stroke...someone gave my son a well thrashed 91 CR125. Please info: What type 2 stroke oil for gas? Ratio? What oil for trans? How much? AND any Ideas why we can't get the clutch to disengage even though the plates seperate when the cover is off..but when it's mrunning with oil it won't? Thanks Steve
Use Yama lube for the fuel at 32/1. Use 80 or 85wt Belray gear oil. The plates may be swollen or the Basket so notched that when running the plates hang in the lil groves. This is a common 125 prob.
Dipstick broken...about how much oil in the trans?
That makes sense about the clutch basket because this one has deep grooves...another question (that may seem dumb..)...seeing as a two stroke has a seperate trans, clutch from pressurized crankcase...can we run the bike for a short time with the trans drained and the clutch cover removed to check clutch operation??? I'm a dry clutch Ducati guy!! I doubt that this would hurt this puppy....
ohh dear god dont i say dont use any yamalube that is NOT sythetic. the standard yamalube is absolute crap. im pretty sure they make a full syn use that. i would probably use bellray mc1, or maximum super M. as for the crank case moblie 1 or golden specrum, full syn as well. i grew up on dirt bikes mainly 2 smokes, i found the benifits of full syn oil real quick and the hard way.as for the mixture yea 32 to 1 sounds good to start after a few rides on a new plug check it and adjust the mixture accordingly a tan plug is best and you are at the idea mixture a white is bad you are running lean add more oil to mixture try 20 to one, a black plug is to rich, decrease oil in mixture try 40 to 1. as for the other stuff im not sure of
i just read your last post and no do not run the bike without oil the crank bearings wont like that at all very bad very very bad, and the bike should share oil from crank to clutch to tranni, only the new 4 stroke crf's have separate crank and clutch oil for dirt bikes. at least from those ive had use with.
hi their i hav a cr 125 1997, the clutch cable it self hasnt snapped and in side the casing in still pulls the mtel thing up (dnt no propa machnical terms) but the bike wont recignises, i hav pulled the clutch in, its like there isant one at all, and the clutch lever is really slack like there is nothing there, pls can ne one help and how much is it goin to cost , would be very greatful thank u Jon.

Mr. jt1990, what you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.
jt1990, It may be as simple as adjusting the cable. I can't remember the arrangement on the 125 but most use a threaded sleeve at the cover with two nuts to lock in place. Use this to take up the slack until you have a small amount of play at the lever.As for Godzuki's advice, the crankshaft is separated from the rest of the case including the tranny and clutch, hence the need for oil in the gas to lubricate the piston and crank. I would not run the bike without oil in the tranny. Also it is not recomended to adjust your jetting with the oil ratio. Two stroke oils are made to be mixed at a certain ratio depending on their makeup and intended use (32/1 is good for yamalube and your application). In addition, if you do plan on adjusting with the oil content, Godzuki has it backwards, If you are running lean you want to increase the ratio effectively adding more gas to less oil. Make sense? As for as the sticking clutch, file down the ridges trying to keep things as flat as you can. Has worked for me in the past.Good luck.
Also........... You may want to leave the 80wt gear lube for the rear end in your car. The trans in your bike would rather have a 10w40 motorcycle rated oil (no car oils or the friction modifiers in them will make your clutch slip).
