I just put in a je 12:1 87mm piston.
I am very impressed with the performance.
And I run straight race gas.
expensive, but worth it.
My bike is like a totally new one after I did motor work.
It made my stock bike feel really slow.
Good luck man.

I just had mine built to a 416, then my sleeve got two groves in it, so I got another sleeve and now I've got a 426. It does seem to pull a lot harder. I run 93 octane, Most of the time i mix it with 114 turbo blue, but I was told 93 would be fine, just nothing less? Is that true?

i really wouldnt go over a 11:1 in a 400 because more than that it will start to hurt ur bottom end. Thatas what ive heard i have no experience with it but i thought id put in my .02

actually the higher compression the more torque your goin to see but the higher the compression the less reliable it goin to be
