I just finished installing my cases. I was going to go with the Holan racks but I really like Caribous fastening system for the side cases so I installed the HB racks. My plan is to rework the HB's into a 'balanced' system eventually. The offset on the exhaust side is a full 3"! :eek1 I've found that the seat fits just fine with the spacers on the grab rail but it would have been nice to integrate a new grab rail with the system, mainly because using the HB rack raises the top-case 3/4". The only other thing I'm not too keen on is how the lower brackets fasten to the foot pegs. I think it's a little ghetto but I'll probably just weld the bracket on anyway. Overall I think this set-up is dandy and I really like the cases and how they look (and attach). Roger with Caribou was great to work with and helpful with the couple questions I had during installation. BTW - Can anyone tell me how to upload more than one pic to a posting?
