Just bought a 2016 M8 SnoPro a couple days ago. First Cat I've owned, always had pro's but decided to make a change. Question is: the sled sat in a heated shop all summer, bought it 3 days ago, brought it home and put it in my heated shop. Started sled up yesterday, came into shop this morning and noticed a little oil under it. Pulled side panels off and hood, and noticed oil in the airbox, appears to be coming from the throttle bodies. The oil reservoir was completely full all summer long. Is this normal to have oil in the airbox??? Sled only has 800 miles on it. Any input would be greatly appreciated!!
