I have a 2004 Sportsman 500 ATP. I successfully replaced the starter by going in from the top and removing the air filter and clutch air duct, as opposed to removing the clutch and clutch cover and accessing it from the side. I now can't recall how to replace, route, and secure the air duct coming out of the clutch housing. And, there is a mounting hole at the top end of this duct. Where exactly does it secure or bolt on to?
