Greetings, i bought a fmdv008 forge exhaust valve, from a private individual at a very convenient price, still new and packaged, inside the package I also have the green/blue/red spring kit. Inside the valve a green spring is already pre-installed, now my thought is which spring will be good? (the yellow spring is not in the kit), according to Forge there is a rough estimate of the pressures at which the springs work. Which one should I install? do I need the yellow one? I run with a manual fpr at 1.2 bar.
