I have 2 2015 1000’s both with about 3500 miles. I have been working on clutches all stock replacement stuff. With the cars in park you hit the gas my wifes car rev’s right up if you do the same to mine it rev’s slower at first then up. When you let off the gas hers drops right off mine tapers off. I know it should have nothing to do with the clutch because it in park.
