Hi,

Did anybody mounted the 50A stator from cycle electric inc in his dyna? (My Street Bob is from 2007)
I would like to buy that stator but I don't know if I have to change the regulator as well?
I couldn't find any email contact on their webpage so I was wondering if some one of you guys made experience with that stator. My audio system is pretty thirsty ;-) So I need more Power!

Thank you & saludos

 

I upgraded to it when mine was a little suspect. I think it was only a 2A increase. They told me on the phone that it's okay to run with your current regulator.

 

why not just replace it with a stock 2007 stator? The stock stator has more than enough output.

 

My stock stator's insulation was questionable when I had the bike apart at 20k:



The Cycle Electric stator additionally has a higher temperature resistance which should keep it looking like this:



The 2A difference probably won't be noticed, at least for me. It was more for durability in my case.

 

Possibly because the Cycle Electric stator is better quality than the stock one. (Oops, I typed way too slow).

 

IMO I wouldnt change just to change it. The HD unit is pretty good. Im glad they are 3 phase. But like Matt if you're in there and its showing its age then go fir it.

 

Yes, to both questions. I had several problems in a row. Stock stator was replaced under warranty at about 11K, just under two years. It went out again almost immediately. HD refused to cover the second one because (just outside of two years) the bike was out of warranty even though they had just replaced the last one.

Decided to do it on my own and made the mistake of replacing only the stator and not the regulator. Fortnately I bought a CE Stator, think it was 40A. Unfortunately, boom the CE one blows up within a year, damn it.

Called CE, spoke to their cheif engineer, told me to go buy one of their regulators and SENT ME A REPLACEMENT stator free. They really stand behind their products. This CE stator and CE regulator have been in since, running 26K now with no problems at all.

Don't normally endorse any products but have to give CE cudos for standing up when the jerkoffs I bought the whole rest of the bike from wouldn't.

 

Based on your experiences. .I'd bet the regulator was the culprit all along. When I bought my CE stator they told me a new regulator would not be required. I wasn't experiencing sudden or drastic failures such as yours, either, my stator was just questionable but checked out okay doing all the tests recommended in the SM.

Just read a tech article today in the most recent AIM magazine on alternators, and the voltage regulator can fail and send voltage downstream back to the stator which will fry it no matter what stator you're using.

Had HD tested your regulator in the first place I'd wager all of that mess could have been avoided.

 

There's no doubt, about that.

However, testing a regulator isn't all that easy to do, nor can you be 100% sure even if you do test it. You can't simulate heat issues or vibration etc.

Given the risk, my recommendation is change them both and save yourself the hassle finding out the hard way.
