An after mod update of the Touratech rack. I took the racks to a local shop, asked them to move the tabs down (top of the relocated tab would be where the bottom of the original tab was) and now no clearance issues. So if you have or prefer the touratech rack then a simple fix can be done to allow for the CJ tank or storage box.
