Hey I am trying to find out the inner diameter of the radiator hoses on a 1991 cbr f2.

 

Can you measure the one you have? Or the OD of the radiator or water pump intlets/outlets (not the part with the lip, the smaller neck diameter.

 

Well I don't have a caliper, but I guess I could get a rough estimate of what it is. The reason I want to know is because I want a trail tech vapor gauge and they want to know the inner diameter for the temperature sensor. i am not sure to what accuracy they want it. I told them what I thought it was, about an inch, but they didn't seemed convinced enough to give me a sensor.

 

ahh. then take a c-clamp and turn it down til it appoximates the outlet diameter. then measure that gap.

 

Awesome thanks.
