My first start of the yr. is allways smoky. I cant see a ft in front of me till I move forward and clear it out a bit. I use citco sea and snow oil. Its cheap and works great.
I was using Arctic cat oil which is good oil but seemed to smoke a lot. I read online that Citgo sea and snow semi-synthetic oil doesnt smoke as much and has higher ratings than the arctic cat oil. And the best part is is ony $17.00 a gallon.... Cat happy
