Need some guidance here. I have a 2005 600 Edge Touring that has about 750 mies on it. When started and idling, it smokes like crazy - enough to fill up a garage full of smoke in moments. It also is spitting a bit of oil out of the exhaust. Only after I have ridden it for awhile does it stop. I've had it checked out by the dealer twice, and the last time they adjusted the oil pump, but it hasn't helped. Could I have a faulty oil pump? Any assistance would be much appreciated.
