VZ - You forgot to add that if we order now, we'll get TWO for the price of one. And that operators are standing by...

yes, very nice! Interesting that the oil mist was what seems like the mid range. I've heard of valve float on the old boxers at sustained 120 mph, non race engine. What would it take for an engine like the s10000rr?

Well, first you'd have to defeat the rev limiter that is integral to the fuel and ignition control unit. Testing just isn't as simple as it used to be...
