how do i know if my nikki modded secondaries are kicking in, im still in the break in period on a rebuilt 12A, the car revs great and when i put my foot in it, it accelerates good, as good as a stock 12A can. i usually shift around 3800 rpms. i have 150 miles on the rebuild.

 

If you got the air filter hat on remove it and move the accelerator lever manually and look at them….they should be opening at high rpm’s…..

ps….do it when the car is off…..

 

they do open, but i would like to know if they are opening as im driving it?

 

The only way I knew they were opening was when I stripped the Nikki out of everything and made the secondary mechanical……then I knew for sure they were opening….😁
