Just purchased a 2007 Rancher AT Gscape. The bike has 18 hours and 80 miles on it. Going to take it in for the 20 hour service. I checked the oil and it looked very clean but would only register when dipstick was screwed in. Measured half way between the low and full marks. Based on manual it is obviously low. Is this normal? Bike had been stored a while. Would this affect the oil reading?
