Where to get venturis for CB's 48 mm throttle bodies >?

[Thorkhild]

its for these https://www.cbperformance.com/ProductDe ... tCode=7358

I asked CB and they said they don't have any. Does anyone know where to find some?

Or is this something I need to get fabricated ?


I am looking to change them to either 36-40.

Errrm... Throttle bodies don't have venturis like carbs do, what you are looking for is probably a set of smaller throttle bodies. 48mm is HUGE for all but the wildest race engines.

what exactly is your problem? Are you finding it hard to control throttle so its very "on off" ? If so look more into your linkage. you need something that will come on more gradually. I had a hexbar setup with CB 44mm TBs and it was really difficult to control throttle. I have a link sync setup now but I haven't installed it yet also this was all on a 1600cc engine. The link sync isn't going on this engine though its going on my new build.

There's a gas station near where I live that has a daily oxymoron on their sign outside, I'm sure they could use this. TB vents, lol.

I had these made up.

I've got a set a 36mm and a set at 40mm

Just need to weld the mounting tabs on.

I can get a set made for you if needed but they are not cheap at a one off but still cheaper than a new set of throttle body's

Now that is a slick solution!! Way to think out of the box!!

How are they working out for you??

Thanks Nate

They are running smooth and pull really well.

I was worries about the step back to the 48mm valve but it runs fine with no hesitations.

I was thinking of changing the valve to the 40mm and just sleeve it straight through but i was worried about the valve catching.
