Anyone notice their jackshaft rubbing the oil tank? I have an 02 sno pro and noticed that the jackshaft is really polished up almost right under the filler cap of the oil tank. Maybe the firecats are a little different, but I see the part # for the oil tanks is the same. Only difference is the low oil sensor. I don't know if this is a problem, but I do have some shavings from the oil tank under the jackshaft. A little nervous. Anyone have any ideas???
