I'm building a turbo engine based on a 1100F.
I remember that's not a bad idea to change the intake valve's springs to avoid accidentaly opening under boost.
I don't want to talk if it's worth or not, I'm building an engine that has to cope with a couple of steps of power upgrades, so they will be necessary in the future.
I remember that gsxr600 k1 springs were compatible and a bit stronger is it right? Or do I have go for APE springs?
Thanks in advance
