Hi, my 07 k9 quit charging and I determined that the stator is dead! WSW is down till July 15th or longer as the website states and though I can find the kits none list big dog specifically! Thanks

Since I installed the voltmeter on mine I can watch the volts as I ride and was wondering what the big advantage would be to go to the 3 phase? I have 13.3-13.5 at idle, and anytime I'm going down the road no matter what RPM's its running at 14.3-14.4 volts. Now I realize its not Amps, but does the 8 additional amps really make that much difference:oldconfused:

Not a lick. Only difference with 3 phase is at idle it's like 14v.

Extra amps are not needed on a big dog unless you got a stereo, heated grips and a bunch of other malarkey.

Hey Guys.

So I just installed my 40 amp on my 09 K9. Pretty easy task but I did not have to grind any tabs nor did I use any spacers and other parts that came in the kit except the rotar and stator.

Did I install this wrong or is it possible that's its pretty much plug and play?

Unless the bosses have been grounded down before the rotor wouldn't fit square without it. Actually I don't think you could get it on, unless you took off the inner primary as well.

I have the factory charging system in my Mastiff but changed the voltage regulator for single phase compufire (after the oem one burned out) and at idle it I got 14.2 volts.
