Rossnemo Racing Superstock Alcohol FZR Shakedown cruise
3rd time out running E85 fuel. Dialing in the vipec ems fuel map. Have it
rerally close, but running it on the rich side to be safe for now. WOT AFR
ratios are from 11.1-11.6. Will close in on the 12.2 target soon.
Accelleration is well, very very good. :) As you can see, water conditions
sucked with wind, waves and lots of other watercraft traffic. Top speed
tuning and testing coming soon on flatwater.

The new FZR SVHO is the upgraded version of the race-proven platform that
Yamaha introduced several years ago. What makes this model tick is the new
SVHO engine, the next generation of the reliable 1.8L supercharged marine
watercraft power package. In addition to the new power, Yamaha has redone
the graphics and color scheme, added a new jet pump unit, ride plate and
sponsons. This is the exact machine that the race team drives.
