Re: what did you do to your motor bike today?
Put a speedo on mine and now we know how fast we're going.
Butter zone (smooth pleasant ride no vibration) 27-30 mph
Fast cruise (some vibration not bad) 31-32 mph
Balls to the walls (Barney Oldfield position, low over the handle bars) 34 mph
(vibration that comes up through your happy sack up your spine to the roots of your teeth.)
My max speed down hill is 37.3 mph! (again low position, with Scottie's voice in my head, "Captain I canna give ya any more, she's gonna blow!")
We compared two other bike speedos and my bro's car so I think we're fairly accurate.
