Forgive me if my search-foo isn't working well, but after reading what seems like hundreds of threads over the past couple weeks it seems like the general consensus (with a few exceptions) is that the first gen OEM side racks (made by Givi) will not work with any top rack without modifying (removing? not positive because the answers seems to be vague and/or missing pictures) the grab handles on the side rack.
I bought the OEM side rack with the G35 bags, and the 447FZ Monorack Sidearms.
I got the side racks on with zero issues and they're nice and solid, great mounting system, yada yada yada.
Then I went to get the 447FZ arms bolted on and I couldn't, for the life of me, make sense of how the "ears" (#1 in the instructions here: Versys 650 '06-09' : 447FZ - MONORACK SIDEARMS
) were supposed to attach to the bike. As I'm sure everyone knows, instructions aren't Givi's strong suit.
I had read a couple posts that said something akin to "you can make both the OEM side rack and a top rack work you just need to bolt everything together loosely." Taking that advice, I got every bolt loosened up so that about 3-5 threads were engaged at each point.
In the end, you need to get the side racks on, loosely, and then remove the top rear mounting bolts (the ones at the rear end of the grab handles) and then put those ears in place and get the bolt threaded in a bit. Once this is done you can get the rear arms bolted (loosely again) at their front attachment point and attach the rear mounts of the arms to the ears. We found it necessary to put the head of the bolt facing the rear of the bike with the nut to the front. Then we used a pair of needle nose pliers to hold the bolt head while turning the nut with a ratchet. I could have modified a wrench to fit in between all the bits and pieces of the bike and racks but my grinding wheel is dead and I didn't want to try to do it with my angle grinder.
Once the arms were attached to the brackets, I torqued all the rest of the bolts down, starting with the four grab handle bolts of the side rack.
