bellmouth diameter?

webfoot · June 22nd, 2013, 06:28 AM

need the bellmouth diameter on carbs so can order slip on K&N filters.
Dont want to disconnect everything to measure. Anyone have this measurement for the 2012? thanks

DaBlue1 · June 22nd, 2013, 06:34 AM

Wouldn't it be easier to order with a P/N?

the thread you posted is incorrect for the listings, the pods are what I want but the listings are not for 250 kawi,
all I need is a number, 1 inch, 2 inch, 2.25? the parts numbers you gave on the thread dont match 2012 250R

Every part listed fits the Kawasaki Ninja 250 and 300. This is what everyone that runs pod filters (in the U.S.) uses and have been for years. The dimensions of the CVK32 carbs are the same size worldwide.

The reason K&N does not list the 2012 Ninja 250R on it's website is because the pod filters were not and are not purposely designed with the Ninja 250 in mind.

Sorry you didn't find the information useful.

That's not the one he wants. He wants dual pods. K&N- P/N: RU-1822 is what he is looking for, but for whatever reason he feels it won't work or it's incorrectly listed.

The CVK 32 on the 86-87's, however the RU-1822 will fit on them as well as the CVK-30. The 30 or 32 in the name represents the venturi exit diameter.

On the individual K&N's (RU-1822) the limiting factor is that unless you are very careful, putting the second one on knocks the first one off because the carbs are so close together.

The R-0990 single unit takes care of this problem. It has two boots sized and spaced perfectly to fit over the necks of the carb intakes. Each boot has its own hose clamp to tighten it down. It's also less expensive.

The R0990 Flange Inside Diameter is 1.875 in (48 mm)
The RU-1822 Flange Inside Diameter: 2 in (51 mm)

I could get on my 1000 and go a lot faster, so your statement is a non issue. Besides, gearing would have to be changed to get anymore top speed for the 250, which I am not looking for, I want better performance of something so I dont know how to ride, give me a break.
