The 03 F5 I have uses alot of oil to me. bought the sled end of last year, two trips with it. First ride, power valves wouldnt open, cleaned them, power valves would open and ran fine after that. However, after idling for lets say 5 seconds, hopping on the trail and getting on it, a puff of blue smoke that was real noticeable would happen and go away. Sled ran good though. But, after about 50 miles and just topping off the oil resevoir, the oil light would come on. It did look real low, would add some and light would go off. This sled did have a recall on the oil sensor(might be called something else)and IM about to put that in, but I dont think thats going to solve my problem. I believe the oil pump can be adjusted from what people say, has anyone else had this problem.
