I'm trying to remove the piece above the front lower cowl. I think it is called the inner cowl. There are 2 pin head clips on the bottom that are easy to remove. The 2 on the top are call flat head pin clips. They are flat with the surface and I can't get them to pop out.
I think the OP is talking about rivets that do not have a center push pin. I made a removal tool from an inexpensive pliers by grinding and filing notches as shown in the attached photo. Thanks to someone who posted this idea a few months ago (sorry I don't remember the handle).
I have a 2006 and tried to remove them. If the head is flat with no way of really gripping anything they are the same ones I had to deal with. I used a dremel tool that had a motor with a drive cabel so you could get into small places. I used a cutoff wheel and ground the head off very slowly. I replaced them with a pin like the one in the above post. The one being held buy the pliars.
My ATV has these things all over it. I found in my tool box a small pair of cutters (don't know the name of them) that cut from the end instead of the sides like a diagonal pair. They work on the same order as what Ron Fuller shows. These things will pop the retainer out every time.
As mentioned above, those things are a PITA to get out. I used a set of needle nose vise grips to man handle them out. I replaced them with the higher profile version used to hold the inner side fairings on. Those are MUCH easier to install/remove and are a perfect fit. The part number for the higher (and far easier to remove) pull pins is: 91549-MW0-790ZA.
