    XLT1200 test run after mods...how's 58.6 sound

    Fastest stock run = 57.4
    Avg. stock run = 56.5
    Approx. 6 gallons fuel, and 1/3 tank oil

    Added Riva heads, Riva S2, and Nujet 6.0.

    Now...

    Fastest run = 58.6
    Avg. run = 57.8
    Fuel tank full all the way to fill hose, 2/3 tank oil.


    That sound about right, 1.3 mph average gain? I should point out that the cavitation and sluggishness on low end is now gone, pretty quick out of hole. Think the 12 additional gallons of gas is slowing me down just a fuzz too? I know forum members usually mention how much fuel in tank when talking about speed.
