Hey guys, I'm thinking about putting a frame mount seat on my 1987 1100 sporty. I've never done it and have many questions about the whole process. First of all ,will I have to remove the metal part of frame where the front part of original seat slides under? That leaves me with the front mount that will be going on for the new seat. I'm going with a spring seat directly on the frame with seat pivot. Will the seat pivot have to be welded on along with the spring mounts? I hope it's a better ride with springs and the shocks already on it.
