Question is, I was surprised that the oil looked like it had done some work in that 50hrs and was wondering when others change their oil? Ski speeds are ranging from 28mph-36mph and some barefooting for fun as well!
The other question was does anyone change or service the K&N filter at 50hrs as well? If so how?
The question would be how long ago did the previous owner change the oil? Otherwise since you dont always get all of the old oil out the new oil mixes quickly and will change color rather fast so I wouldnt worry to much, unless it is black after 5hrs of use or milky then something might be up.
The K & N should last you more then 50hrs easy, I dont re oil the one on my car until 3000 miles or so and that gets filled with bugs, dust, pollen, you name it. I think you are ok for a while.
