Hey forum, so I recently purchased a "bug-eye" cafe racer seat(1. picture) along w/ the universal mounting kit(2. install instructions) --- vvv

Let me start by saying, I'm still a novice and still learning. So please share your knowledge :).
I took apart the seat and later detached the tank from the frame. Following the instructions for the seat mount, I tested to see if the baseplate for the mount would fit on my frame. It looks to fit exactly with no part of baseplate sticking out.

The problem Im running into is a little groove on my frame. It prevents the cafe seat from proportionally sitting on the base plate w/ the wood blocks as well as the baseplate making contact with the actual seat. My real question is, will I have to cut hump on my frame in order to sit my cafe racer seat on frame? Do I need to buy a new frame or is there another way around this?





Ignore the wood blocks, I goofed here. The bolts should be inwards based on what I saw on the instructions. The issue here is that the battery stops the screws from connecting the top and bottom block. I think I have to cut the screws too?


Thanks in advanced!

I see that you bought a "Universal" cafe seat. So you do understand that it is not going to be a bolt on piece. I also looked at the installation guide. If you notice they are installing it on a totally different bike then you have. I think it is a Honda 350 they are working on. You will notice that the frame on that bike is straight horizontally, where yours dips down, and then curves up. This is why the DOHC CB 750's are not very popular for cafe conversions. Usually when some one cafe's a DOHC, they make their own seat from fiberglass, or aluminum. You would probably be better off making your own pan with fiberglass then trying to mount the universal seat, and trying to make it look right. If you use the search feature on the forum here, you will find threads that show how to make a seat. I did a modification of one in my "Just what the world needs" thread. However to answer your question, yes you will need to remove that bracket.
