Where can you put transmission fluid in a 1999 Kawasaki prairie?

Well, If I remember correctly. It should just use 10w40 motorcycle motor oil and it would go in on the right hand side (you should see the plug that you unscrew to add the oil). The prairie is belt drive, so you should not have a seperate transmission. Then you would need to get the oil for the rear (wetbrake oil if no external drum) and front differential fluid.
