When I decided to try Land Speed Racing in 2017, I used my old Pro-Twins Guzzi which
had been sitting in a collectors heated warehouse for 25 years. It had been clocked at 142
at Daytona, and sure enough I managed to set a record at 142 on El Mirage dry lake.

what RPM I was topping out at. 135HZ*(2cylinder/2 revsperbang)*60=8100RPM:
