I don't have the Gunfighter but I do have their dual tour seat and I have no issues at all with the OEM bags. I am also using the OEM mounts and OEM stays which are both needed to mount the bags. Possible made of gold to account for their price.
There are 2 different OEM mounts, one for single seat set ups and one for dual seats. The stays are the same for both. You can get the part numbers from here...

There is a nice post here about installing them...

As for the risers I have not done it personally but I have read stories from people that have, well not risers as such but new extended bars. The short story is that it is not easy. There is no slack to do anything with the wiring, hydraulics and the control cables so apparently it is a ******* of a job but doable if you are super keen.
