Different valve springs???

Did a search on here and couldn't come up with anything. Was wondering if anybody has some knowledge or access to it about different valve springs for the f4?

What i'm trying to figure out is i have some springs that have pink paint on them, while others have pink and white. Would like to figure this one out and possibly find a place that can specify all the different spring and valve options for the F4 from at least 05 to present.
Didn't know if the coloring system was something like the Jap. manufacturers use. Different colors for different spring weights and length/height.

Noel I think varium is saying that some of the springs in his bike now are marked with paint that is different to other springs in the same engine.

Ergo, is it possible that the springs are of different specification to one another?

Rather than varium wanting to change the OEM spec.

varium, I'm not aware of different spring options in MV engines. I think that you're safe with the springs you are running now, the different paint probably has a story behind it but doesn't necessarily point the finger at differences in the springs themselves.

If it's running fine then don't screw with it.

springs?

varium;

since you didn't like my previous answer.........

ask Tim Witham of S&W
ask Ed the Camfather

or have an in at Associated Spring

i used to sell valve springs to all the bike suppliers except for Pops.....he couldn't believe Tim was bending him over that bad LOLOL

1st you need a spring testing machine
2nd you need a chopped up head and a stroboscope
then you need a spring engineer to tell you what you need to avoid harmonic disasters

Tambos use different springs than contemporary models.....
MV's manuals only spec spring lengths......

have fun
