So I recently purchased an 81 CM400T. I know there's alot of people who advise against getting a CM to build a Cafe, but I decided to give it a shot. So the question I have right now is regarding the seat. I've done my research and seen several CM's with the seat I'm going for but I can't seem to get over the "dip" there is in the frame. Anybody have any ideas how I can go about attacking this? Or can point me in the direction to read up on? Thanks in advance.
