Be cautious with the CNS ported intakes

I have cns can not get it dialed in correctly. spent way way too much time trying I have raced for several top motorcycle companiesfor 13years of my life,I feel my time should be used enjoying life not spent %%$#^% with a cns carb. With that said do you feel the makuni or dielorto shows better performance??
 
The CNS was not properly field tested, that much is certain, its a mikuni bootleg so all the tuning tricks for a mikuni will work on it, they are just so badly out of adjustment from the factory that they just don't seem to work, after careful re jetting and tuning they work very well.
As far as breakage of the carb body is concerned, I've never had that happen with a stock GT5R intake, that looks like a downward shock caused damage.
I still like the Dell Orto SHA series carbs.
Ever consider a support strap? think of it as a jock strap for your carb.

Carbs are getting ' pile drivered '

Looks like you need a way to support carb, possibly a spring from carb bowl, to engine case ? I remember motorcycles having a metal brace that bolted to carb fuel bowl screws, that must be why they were there. Some riders removed them with no consiquences.
 
Yes they do

BTW.... I gave up on those POS cns carbs. I would highly recommend a mikuni VM18. The only issue with it is that you have to use a short CNS intake from pirate and sand the white plastic part that goes around the intake down to fit around it. It won't fit on a regular intake. Other than that, it's the perfect carb.

I agree and is why I will be running a VM18 on my second build. Have the intake and now waiting on the carburetor to get here since the warehouse messed up and sent me the wrong thing. Here is the intake I am going to run. Shows the difference in size over stock.





 
I don't have any experience with the dellorto, just the Mikuni VM-18


The Dellorto SHA or the SHA clone carburetor do not have a low speed adjustment. I am running a SHA Clone and they are OK but not near as tuneable as the Mikuni. On the SHA and SHA clone the only adjustments you can make is to idle speed and main jet. With the Mikuni it has a low speed adjustment, idle adjustment, you can change the mid range jet, high speed jet, the slide cut out and the needle height. If you want quality get a Mikuni and adjustability get a the real deal. It will save you a lot of headaches in the long run. Did you change the slide in it or are you running the stock slide that comes with it? From what some others have said the slide cut out needs to be changed. I all ready have some extra low and high speed jets as they all so recomend changing them. Jaguar had a really good site and one of them is about using the Mikuni.

I deleted the link for the Mikuni as the seller is giving me the runaround.

We have an offset intake manifold as well that works really well .
It's a three-piece kit with a vibration dampener in between a lot of complaints have come through with stock intake manifolds breaking because of vibration so we separated into three pieces to melt aluminum Barb pieces 1/5 motor side one fits carburetor side and a rubber dampener in between the two that keeps it from breaking off I agree the Mikuni's are the way to go
