a stock bike makes about 100hp on 11psi boost which starts at just under 4k rpm so it's pretty doggie down low. The 810 kit gives you more bottom end and with forged pistons allows you to crank up the boost. I dyno'd my '84 3 wks ago and made 202hp on 24lbs of boost. I installed a button-controlled
2-stage boost solenoid which is like having nitrous but never having to fill a bottle. The only newer bikes I've had were a '91 zx11, a 90 550 zephyr (for girlfriend), and a 01 Duc 748 which I sold 3 mos later(hated it). I just bought a 05 919 which
is when I found this site and could not believe the overall "zoominess" of the thing and how light it feels. A stock 750 Turbo weighs about 550lbs, porker! I havent weighed my naked Turbo yet but I think I shaved about 100lbs off it so hopefully it will feel more nimble, and with 180hp it should boogie pretty good.
I've already been thinking about turbo-ing the 919 but without redoing the top end you could only run a few psi of boost without blowing it up. Besides,
with my other bikes being older and having a bunch of mods, i intended the
919 to be the mild one. Boost is so addictive though........
sorry for rambling, i love these things
