What is the rate for the 0646-035 Orange/Black. I think that was the stock spring for the 2010 M8 HCR inthe 6-9K feet range.

Thanks

By the way my tach is reading a max rpm of 9020. What the heck.

Going to keep a close eye on it this weekend and see what it is really spinning.

Running bone stock 6-9K foot setup except right now I have the Yellow 0646-229 spring in.
