i have never bothered with mine and ridden in the snow before. what i did do is drill some holes on the inside of the inlet manifold so the gas air mix didn't have to travel as far to get there. if you work out the distance from the carb to the rear cylinder it's a long way there, think it was about 3/8th hole for rear cy and 5/16th for the next. never had trouble with oiling either.
