I have a 05 Iqr with an 08 600 ho I have no shims under the motor right now and I was told to shim it up so I can get the air box on. How much to I shim up the motor on the back side? I tried to cut a little off the bottom of the air box holes to lower the boots and that did not help. And I tried some diffent boots that polaris makes they are close but they still did not seal. I know a lot of you guys say its hard but damn this sucks. Any more info or tricks would be great. Thanks Kerry
