Here's a sample of the endurance of the stock XS650:
xjwmx...........50,000 miles
jetmechmarty...............53,000 miles
motor650b..............62,000 miles
cmyoch.................65,719 miles
xs1961.................90,000 miles
cowboy3669...............100,000 miles
spockwerks.................114,000 miles
TwoFitty......................120,000 miles
dps650rider................136,122 miles
It seems the stock (360 degree crank) engine is very durable.
For the record my bike is rephased. I for one am very happy with the difference it has made in vibration reduction.
