I'm about ready to run the stock tank and carry gas on my back. Attempted to install the IMS 3.2 tank on my 2007 YZ450 today. Unfortunately the radiator shrouds on both sides of the bike are a full inch from making contact with the radiator mount location. Not sure if I have a defect, I can't see anything that is installed incorrectly. I do have a scotts damper which raises the front tank mount (near steering head) about 3/16". BUT I read on TT that many are running a damper with the IMS tank. The bike is brand new so the radiators are not bent. I also realized on my first trail ride last Sunday that I averaged 20 mpg, not gonna get too far on that. I called IMS but they're closed, any advice would be appreciated.
