If you are riding a dirt bike you probably have a leaking water pump seal allowing transmission oil into the antifreeze. If the motorcycle is a four stroke street bike the leak is probably in the head gasket.
I think your model is a water-cooled model with a radiator. Likely you have a leak in the head gasket or (hopefully not) a cracked block that is letting the coolant into the engine cylinder making all the white "steam" and stinky exhaust as the coolant burns.
DON'T CONTINUE to run/ride the bike until you fix this situation as it can blow your engine with all that water in the cylinder.
Check the oil... does it look milky or foamy... that would be confirmation that you for sure have a coolant leak into the engine. But you still could have the coolant leak even if the oil looks fine.
You can replace the head gasket if you can still find one available (you bike is a "vintage" machine for sure!) or may wish to find a motorcycle repair shop that works on older bikes. You may have to call around... many motorcycle places do not work on older bikes... check your yellow pages or google for vintage motorcycle clubs in your area... you likely will be able to find the correct place through them.
If YOU plan on trying to replace first the head gasket, and then the whole block if necessary, then please repost with that request.
Hope this helps or at least explains what is going on...

The water pump is in the motor case and has a leaking seal. Anti freeze is leaking past the water pump seal into the transmission. Take your water pump apart and replace the seals. The fluid should be escaping out a weep hole in the bottom of the pump, so when you have it apart be sure and dig the mud out of the weep hole to keep from filling the motor with anti freeze if this ever happens again. If there is no weep hole then it must not have been designed with one.
It should be just that, a leaking seal, gasket. The water pump is external on that bike and doesn't go anywhere but the cooling dept.It doesn't get mixed with oil or anything. Take off the pump itself and replace the gasket. I think that should do it, unless it is the pump itself leaking. Suzuki RM125 RM 125 Water Pump Housing,,,, That is an ebay ad. Just in case. Hope this helps.
The only thing I can think of is that either the banjo fittings are cracked, or maybe you put the fittings on wrong. Where is it leaking, at the cooler, or at the motor? And is it the hose that is connected to the oil pump (right side while sitting on the bike), or is it the one that is connected to the engine (left side while sitting on the bike)? You could also possibly have a pinhole in the hose or where the pipe goes into the hose. How bad is it leaking?
The water pump oil seals, yes. The seals keep the gearbox oil separated from the water. The only other way water can normally get into the gearbox is if you have a cracked center casing, a loose oil filler plug, bad head gasket, bad cylinder gasket, and condensation. The normal culprit is the water pump seals.
Below are generic things to look for if getting a used bike. Does the engine start easy and idle smoothly? Does it accelerate without hesitation? Does the clutch engage and disengage smoothly? Is the clutch lever easy to pull? Any oil or coolant fluids leaking after a ride? Do all gages work? Lights, horn and flashers? Any red lights on the gages lit up? Any computer codes flashing? Do front and back brakes operate and stop smoothly? Is the motor oil pretty clean or really dirty? (Sign of how well the owner has cared for the bike). Is the oil "white-ish"? (water in the oil. If motor is water cooled it's usually bad water pump seals). Any funny sounds from the gear box? Anywhere else? Does it shift smoothly up and down the full gear range? Neutral light come on properly? Sprockets still have rounded tips not pointed? Well lubricated chain? How much adjustment is left in the chain? Good tires? How old is the battery? All lights work properly? Is the upholstery good? Plastics cracked or broken? Gas tank badly rusted inside? Do the wheels run true or weave? Do the forks look bent from a side view or front view?
YOUR BIKE HAS A POWER VALVE (DIAPHRAM FUEL PUMP) THAT GIVES A SHOT OF GAS EACH TIME THE THROTTLE IS TWISTED. WHEN THE BIKE IS HOT, IT FLOODS EASILY. DON'T HIT THE THROTTLE WHEN STARTING THE BIKE WHEN THE ENGINE IS HOT.
