I just had Cameron Jones build an ECU flash for me around the DHM piston, TB cam, Vinny's ported stock valve head, and a ported 26mm throttle body. These parts with my own modified airbox and Yoshimura RS9 full system made good power on his dyno. I'm sure he will be posting the dyno graphs in his Dyno thread soon enough. Numbers wise it pulled 14.82 HP @ 9300 rpm, and 9.29 ft-lbs of TQ @ 6950 rpm. From the graph I saw it looked like it made over 14 HP from about 8400 - 10500 rpm, and then it falls off hard after 10500. He has the limiter set to 11000 rpm.

I'm going to be tearing into the Grom pretty soon, I'll be updating my build thread shortly with all the new parts I have ready to go in.

Got dual valve springs installed? My buddy has a ported stock head, TB cam, rev wedge with a Koso 34mm throttle body - pulls hard to 11000+rpm.
