Hi there I was wondering if anyone new the colour of spring Im susposed to use in a 1990 Indy 650? I look on the Polaris site and they say gold. When I use the gold spring I engage at 6000 rpm when I try the blue white spring I have I engage at 4500 rpm. I was wondering if anyone knew which spring works best with a stock Indy 650??
Thank you
