It will work but you will eventually seriously damage the engine. Water in the oil will cause it to emulsify preventing it working properly as a lubricant. The water turned to steam will damage steel by causing rust (Oxidisation).

If you have a water cooled motorcycle and you have water in the oil is it an indication of a serious problem.

For instance, if the cylinder head is leaking water into the cylinder because of a faulty head gasket or warped head. The cylinder will fill with water. As water is non compressible it will cause the piston to bend or break the con rod causing significant engine damage.

If it fails at high speed on a bike it could be fatal to have the engine seize.

I prefer water wetter for the coolant

Could be a bad head gasket, cracked head or cracked cylinder. You wont know which one for sure until you have it disassembled.

your water pump seal and oil seal have failed on the water pump shaft. Replace both seals noting which way the seals face. replace the water pump shaft if it is scored. Chaz- Moto DC

It would talke a lot of water to get into the pistons under normal circumstances. Pull the plugs and try to give it a kick. If there is water in there, it should come out when you kick it. Check the oil for water contamination. If you find any water, change your oil immediately. Oil should look like honey or it shuld be black. Anything else is contaminatied. If you find water, squirt oil into each spark plug hole and turn your engine over - get local advice from your motorcycle shop.

Drain the oil and water. Remove the radiator and exhaust pipes. Remove the oil pan on the bottom of the engine. Remove the bolts holding the water pump/oil pump on.

well when you have water and oil both leaking it most of the time means a head gasket or in your case a jug gasket

Some manufacturers use a hybrid cooling method where engine oil is circulated between the engine case and a small radiator. Here the oil doubles as cooling liquid, prompting the name "oil-cooling." Suzuki has produced many "oil-cooled" motorcycles.
