Can you "Make it work?" Yes, you can. You can make anything work with enough time, energy, tools and perseverance. The things you need to watch out for are (and I say this after working on only 750's) the shape of the pipes and any deformities. The 750 pipes have a few spots where they have been clearanced to make room for Brake linkage and what not. You may find some bends in your stock pipes where as those Dunstall tips are just straight.
Just thing to think about.
