Mine cost aussie$430.00 but the guy I bought it from imports from Japan direct and tends to be a fair bit cheaper than most lhs'
who ever does Kawahara where you are should have access to them.

Re-Performance.

One word....BALLISTIC

This thing makes my Novarossi seem stationary, and I do love my Novarossi.
Very tunable, heaps of lowend grunt and top end is off the planet
I rang the shop I got it from and allthough no figures are quoted he estimates 1.3hp from the sport version and 1.4hp from the race version. The key difference being the race has more bottom end with the top end performance having no notable difference.
Running in was a dream allthough after the first setting change the suburban driveway was no longer an option as the Centax was set a little too high and the holeshot of the car was uncontrollable (ill remember that next club drag day!).
I would encourage anyone to look further into these.
