I bought an 11' IQR this year and love it but I am having a lot of problems, mainly gas mileage, cant go riding with the family because I only get 5 MPG and there are not many 91 octane non-oxygenated gas stations around me (New Ulm MN) Just re-geared yesterday to a 19-43 which seemed to help a ton but we were only able to ride it for 10 min. Also looking into a bunch of different options including clutching, tempa-flow, more gearing and were adding a 2 gal tank onto the back of the sled. I opened a forum under "experienced IQR owners please" let me know what your doing and how things are going for you!
