Dyno numbers for YFZ450 with Athena 478cc kit?

[Lifted_Dakota]

Just wondering if anyone had dynoed an Athena yfz450 big bore kit and what kind of numbers/mods you had.

I've also got a a full White Brothers Aluminum Pro Exhaust, Pro Flow intake.

With the athena kit (12:1), 06 ported head, cam mod, 06 crank, ESR airbox eliminator, 44mm lectron carb, nmotion pipe, white brothers cdi, and the wrong gas, we were putting out about 53 rwhp on the Little Sahara Dyno. Should be a little more now with the new mods that we have done. We were running too much octane for the motor at the last dyno run.
