    Allright, it's been 180 km since the pistons and rings so I tried it. The geotracker gps for android said 159 km/h (98,8 mp/h) in a "free" distance, not sure what it was. That's with a 21/39 gearing. According to the gearing calculator, the theoretical top speed is 92,5 mp/h or 148,9 km/h.

    Btw, the speedometer indicated pretty close to 180 kph ( 111,8 mph), I think it showed like 178 km/h (110 mph)

    I put my build on hold, as I am trying to finish my 835 motor.
    But, when I tackle it, I will come find you.
