I had the dealer put my OEM bars on and I did not get the tool to remove them which I want to do now while they are not in use. Is it a Torx 25 bit? It's very hard to get anything in there to even see if the fit is right. Is the tool they come with have some special angle to facilitate being able to turn the bolts more than a quarter turn if that? I'm no mechanic but this seems like a royal PITA to deal with. Might just leave them on but I think it looks better off and then there's the MPG thing.
T30 Torx bit. Here's the instructions.
