Yeah, I had a problem with the IM I bought from them through a third party promising a map and ended up with the "we only supply maps for Yamaha" response. Graves' website used to say IM maps for all bikes, no matter which one you looked up.
After I raised a stink, the third party changed their website, but not Graves, initially (many months later it wasn't changed, but is now). When I asked them for some form of compensation, Graves wouldn't even entertain it, and the third party tried (not the greatest effort, however), but I decided on another course of action.
Consider that my welcome.
