I heared from an HD dealer that the buell XB stator often fail
your dealer mouth-piece is incorrect. having owned approx. 25 XB models to date.... and having accrued well over 60,000 miles on combined XB's....i have only replaced ONE voltage regulator. XB charging systems are simple in design and very reliable. having said that....longevity entirely dependent upon condition of wiring harness plugs....VR ground....type of primary oil used....condition of and quality of battery....and components being repeatedly exposed to excessive temperatures.
