16.3 HP after 2.5hrs on the dyno today, i've learnt there is a huge difference between peek hp & usable hp!! Little less HP but it last longer with out diving!
The blue line is todays runs, and orange is from a few weeks back.
Mods in progress - Brembo Brakes with 208mm disk on front, YZ250 master cylinder, rear brakes, & a 155z - but that's another story
