I think I need a new voltage regulator.

You are also using an aftermarket high output stator. My stator is obviously tired. Hopefully the one I'm getting isn't as tired. If worse comes to worst I'll get the super stator.

As for good money after bad... I'm probably going to go back down this path with my shaftie so I'll already have most the options on hand. Once I get past that i'll pass on what I don't use.

The FH MOSFET R/R ain't gonna do anything to help the situation.

There is a long history of Dyna S giving problems on single-phase Kz650's. Not all of them, just a percentage of them. Replacing the stators and reg/rec's wouldn't fix the problem.

It was assumed there was a batch of stators or rotors that made it out of the factory with slightly weaker output. This was fine until a Dyna S is installed. The Dyna S draws about twice the power as a stock points ignition, and much more if 3 ohm coils are used.

It still doesn't quite make sense, though, because one solution was to convert them to 3-phase using 750 parts, and that's what you have, presumably.

Apparently.

I contacted the seller and he said he would send everything he had to me...

I know he's just trying to provide good service but i don't know what to tell him.

I found a rebuilt Rick's stator, I'm wondering if I should get that one or maybe I should send one to Rick's for rebuild. I went to their web site but they don't have one listed for my bike. I currently have 2 extra to send them now.

I do have a Dyna S w/3 ohm coils. Everything else is presumably stock except what has been discussed here.

I've had them on for quite awhile and I couldn't say whether there was any change when I put them on or not.
