I emailed bill and this was his reply:
"We have about 11k miles on our test bike, 1000 hard miles with the turbo on
it. It still runs great, a blast to ride. We have the bike apart right now
taking pictures for the installation manual, but plan to get more pics on
the website by the weekend.
Reliability - we are specifying Castrol 5w-40 synthetic oil for the bike and
frequent oil changes. This will help the turbo live but will help the engine
live also. The extra power will cause more wear on the engine and
drivetrain, but if you maintain the bike and use the good oil, not too bad.
Honda builds strong engines, and the 919 is really a 900RR, which is plenty
stout. So, if the system is installed properly, and you use good gas, and
keep the boost limited to 7 psi, you shouldn't have any problems."
His screen name is WAVE_Guy and he said he'd be here tomorrow.
