Yes beebone, i had 0.8mm gap with the silver hard Mugen spring ( not ultra hard grey spring) i wanted to run a little less but the silver Mugen spring is to soft and with a 0.5mm gap, it was nice. just be mindful when setting it that you have 9.2mm from end of crank shaft to top of thread.
hope it works for you
