These are kind of a brownish black.. Do springs are coded with colors? I saw there are yellow and blue so do you know which ones do i have here? what RPM are these? And what difference will these make on my Dio?
Thank you.

When talking about clutch grab springs, 1k's 2k's or whatever, it is always 1000 rpm or 2000rpm HIGHER than stock.az_slynch wrote:Doesn't the color code specify how many RPMs the new spring takes up above the stock spring's take-up speed? A yellow 3K would make more sense then if your stock spring hooks up around 2K. Idle on these 50cc Hondas is about 1800, so ~2K could be a reasonable assumption for a stock spring. Yellow would just hold back another 1K before engaging at 3K RPM.
