My bike made the power with nutec yesterday.
54 rear wheel hp on a dynojet(corrected)
It is a 97mm Gore/Rohrich piston (14-1)
Falicon sprockets 105in lca, 106ex lca
Kibblewhite head
Arrow pipe and tapered header
165 main
for the record it made 52hp on pump swill
On the same dyno a dialed in yz426 made 48hp.
Now I just have to learn how to twist the throttle slower.

Holy smokes!!!!
That's a very healthy number! How long should that motor last?

01' WR426
99' YZ400

Uh, like twist the throttle...

It has already made about 80 passes on the dyno.
I have ridden it on the trails once and don't intend to seek any more power.
I will keep y'all posted as to the longevity.
But my experience is if it doesn't scatter on the dyno it will be ok.
Oh yea, it also had 34 ftlbs of torque.
This motor makes more torque and hp than my old 501 after I built it up.
