OK - Full Disclosure - my Stator (on my Daytona) just fried yesterday
Now that stator is about 10 years old at this point and ran
for at least half of that with a MOSFET Shunt Regulator, before switching to a Compufire Series R/R then an SH847 about 4 years ago (but it has done relatively low mileage in that period)
But I STILL stand completely behind the fundamental technical advantages of a Series Regulator in
REDUCING the probability of stator failure.
However I do want to be open and show my failure in spite of the SH847
i.e. it will
REDUCE probability but cannot necessarily
GUARANTEE that you will not have a failure.
Bottom line - I STILL recommend this Regulator - especially on a Rocket with such efforts required to replace it (mine was out in about 10 mins total yesterday, from pulling into garage, confirming dead from teh isolation test and pulling the cover/stator)
And I would STILL recommend RicksMotorSportElectrics as a replacement for stator.
