7 hours? You're in VA....right?!
That was a 929, not 954 although they are quiet similar. 929/954, while being larger displacement motors and lighter in weight may not have the aero advantage and DEFINATELY don't have the cams or RAM AIR.
On a stock geared 929 with a slip-on, no mirrors it went 169 on GPS.
On the 98 ZX-9R stock geared with a slip-on I've gone 168.7. Sounds the same, right?
But the 9R slams into the rev limiter hard and early, the Honda waaanes past peak power with its softer cams.
I dropped a tooth and the 9R still went faster....the Honda as it sat probably wouldn't have.
