I have a 06 Raptor 700 and have been burning alot of oil. You can smell it when your riding behind me and I heard this could be your rings. Is this true? and is there away to test this. I rode about 100 miles this past weekend and had to add almost 1qt of oil. I do have alot of miles on the quad.... One more thing if it is the rings whats the avg price to fix?
