Topic: Velocity stack dimensions

[70CB750]

I was just wondering if anybody has dimensions for the velocity stack. I asume the shape is a paraboloid since in air/fluid velocity it typically works better and the narrow end must fit the carb (40mm) but what is the length and bigger diameter?

For K0 of course.

Hi Prokop, it's a bit of a black art like the correct length of exhaust system to suite a particular motor.
What works on one motor might not work on another.
There is a guy on here that makes real nice velocity stacks, I'll do a search to see if I can find him.
