That's what I used when I raced my 1.0, it's a matter of trial and error, for me anything not in that range was either too loose or too tight. I just took the same range for my 2.0 and it has worked soo far. From what I saw the stock setting was flush with the 2.0 spring, being that the 1.0 is a little softer you would need to tighten it a little bit more to get the correct tension, just my 0.2

The top aluminum saver is on it's way.....
