 :agree:
Get a Rick's. Better than NOS for a couple reasons. As Mark mentioned, the NOS has been sitting around for decades while the Rick's is new. Rick's stators are also better built than OEM. I bought one a few years ago for one of my bikes and it's really nice.

Yeah, I see they won't take it back so that could be a nightmare - and they want too much.
This does look interesting, though: https://www.ebay.com/itm/154287303614?

That said, I filled out a Rick's part repair form to print off and send. Gotta respect our US business peeps.

this is deja vu to joshes rz, even considering the overseas one.  Tim, if you're reading this... right?

Josh must be an alright dude :dawg:
Was there a thread on his terrible plight?

I did err by titling this one with "YPVS".

Appreciate everyone helping out!

m in sc

there was not  yeah hes a great dude but was super super frustrated. and rightfully so. this was also on a freshly rebuilt motor and a fresh painted bike etc. he poured a SHITLOAD of time, effort, money into it doing everything right... except that. and now he is literally just waiting otn eh stator to get back, should be Monday or Tuesday

mnein just rebuilt the engine and brakes on this one. What could possibly go wrong with 28k miles, multiple wipeouts and 40 years?
Would be nice to see a photo of Josh's if he's willing to share - so we can drool.

m in sc

sure.

i realized i hadnt uploaded any '25 deals gap pics, so i uploaded them just now. we spent all week trying to diagnose it.



weeks before, we had it at the house after it blew the motor, right after the rebuild trying to sort it out then as well. carbs, ignition, jetting, swapping parts etc. I always 'felt' it was the stator, but took a while to confirm.

Thought that I replied that the paint looks excellent!
 
So, 2+2=4
That bike is an '85, it's 40 yrs old. Mine's an '85. Apparently, the winding protection lasts 40 years, period.
Rick's must be seeing a lot this year. They have mine, but I haven't heard back and might not for a couple weeks.

Photo of that red RZ in the garage looks tasty.

m in sc

yeah thats in my garage trying to figure out wtf was wrong w it in april.  i think they had joshs 3 or 4 weeks. He got it back and has ridden it every. single . day . since. ....And is smitten. I ruined that poor boy.  :devil:  :clap:

My original stator is hanging in there, but the previous owner told me the controller blew so he installed the Zeel.

I understand the smitten thing. He probably has more power than me, but I had forgotten how that torque felt. I'm smitten by the power valve concept.

Matt put a fresh 15T front sprocket on too. I'm sure that's part of what I like. Seems just right for an RZ.

RD400C, that Zeel schematic sells itself.

Rick's called today. My stator actually checks out fine. I'll be looking at some wiring beyond the stator pigtail on the RZ to see if there was an open somewhere in the red/white wire.

I'm thinking to get them to rebuild it anyway because of age plus that caramelized burnt look; while also assuming that there's a possible problem in that red/white wire since I measured closer to the cdi box instead of the stator pigtail.
Is there a transistor in the cdi bad? I dunno.

How's Josh's stator now?
Did his look toasted?
