416 jetting

[dobber21]

i might be getting a 416 bore with a HC stage 2.

i have a full yoshimura exhaust cdi box and im running a 170main jet, would that be sufficient or would i need a bigger or smaller.

what do u guys think?

heres mine it would be a bit more than what i am at with a full exhaust and a stage 2. steve

I run a 170 main, 40 pilot , needle in the 2nd clip from top and the screw that depends what day I run it cuz it varies with the weather.

i didn't have to re-jet mine whenever i put a 416 and Stg. 2 cam in. I actually had to drop the needle one clip cause it was running too rich. I have a 150 main, 42 pilot, needle on the the 2nd clip and my a/f screw is 2 1/2 turns out
