I have a 2009 Kawasaki Mule 4010 Trans fuel injected, and when going up a slope using 4x4; it started to throw blue smoke from the muffler. I stopped for about 1 ,minute and started engine back up and nothing....no smoke and everything seemed fine. It only had 29 hrs, One thing I did noticed is that the more I drove it the fewer times that it was smoking....after a few days of using no more smoke. Oil level seemed to be fine and oil looked really clean. Any thoughts?????

 

My guess would be oil has got into the airbox, either because the machine has been rolled whilst still crated up, or the shop doing the PDI has lifted it wrongly to fit the undertray or something. Other possibility is valve stem seal not on properly, and pouring oil into a manifold when it gets covered in oil due to the angle the engine is at. I had an MG TC that did this trick on steep hills, but they had metal shrouds to deflect oil out of valve guides, modern engines have rubber oil seals on the valves.
