For the sake of fairness, I have not done this mod so I can't speak with experiance. But I am skepticle that a carb with these changes would have good street manners, remember it is a Race tune Mod.screwdriver said:

That's the premise of the modification, to enable the CV to work with Velocity stacks. As pointed out by HD this is a modification Honda did for race bikes most likely with flowed and ported heads and minimum capacity of 996cc Kit A. Your jetting will have to be modified to suit your situation and that is not always an easy process and can be expensive as you will need 4 of every jet in a range of sizes as well as an enormous amount of patients and maybe Dyno time as well. Do not expect the mods on the 1st page will get you a sweet riding bike, that's only the 1st step of what could be a lengthy process.
Like HD I have not personally tried this modification in the past I used GSXR Carbs and for my current project have a set of proper flatslide carbs, so it will be a while before I get round to trying it.
Although the document is available in a number of places if you know what to look for, I had been hesitant to post it as it's not a magic pill for pod conversions on road bikes, well not until many people have tried it and posted their set ups and experiences.

I think you would be better off saving up for some Mikunis or Keihin flat slides instead of messing around by modifying the CV's. The CV's work great, on a stock bike but they are so finicky once you start modding. After I put smooth bores on my 900F, it wasn't just faster but it even cold started so much better. I think the only two reasons to keep the CV's are 1. for budget reasons or 2. to restore to original. Just my opinion and I know that a lot of people don't want to spend as much on carbs as they spent for their bike in the first place and I understand that too. Oh, number 3. they look great when the tops are polished shiny 8)

yeah after looking for rebuild kits for the carbs, plus all the time its going to take me to tear them apart, i think i'll just end up getting the keihin's

They are never 100% complete. You build and ride and modify and tweak and ride and change and so it continues as you work out what you and the bike really need to do to work together. Often the changes undo what you did first time around to improve comfort or it's the search for better handling and performance that sucks you and your wallet into that black hole.
Other times it's the "look". What looks great first time round sometimes looks old and tired 10 minutes later. Other times we build what we had in mind and decide that we don't enjoy riding it and change it around to make it work. It's like any relationship - you both keep evolving until one of you stops changing and the other starts to look for a new play date.

I like the British Racing Green with white stripe. Those are Canada's racing colours.

Hey screwdriver, just an FYI. After I bought 6 I needed off e-bay and 2 of them were not the size ordered (!) I went to the local Honda Dealership parts counter who pulled out a master shim sellection bin box from the years of their Service Department swapping shims. They had a "swap" price of $1 each... You bring in a shim and then swap it for the size you need. And because there were a Dealer they had the hard to find "half sizes".
Might be worth checking yours. 8)

So, after looking around for a while and reading through tons of usefull advise, I started my own build. I've had some experience with bikes before, but never actually built one. So this is going to be a 'learning by doing' kinda built project
I bought this '81 CB750F a few months ago with the idea of transforming her into a cafe racer. But she looked so good I wasn't shure about changing the looks, so I've been riding her for a few months. But now the winter kicked in and she's sitting alone in a dark and cold garage, so I deceided to give her a make-over
Because the built is meant to be as low budget as possible, I've decided to create and do as many things myself as possible. I started out with the seat to get the iconic looks to it:
Still some work to do on it. I might start a build post as well after we have made some more progress on the bike.
