RZ350 Stator ID and swap info needed... 85 to 86
Did some searches here but only finding scattered bits and pieces. Puttin together a working motor for a nice 86RZ rolling chassis in York, PA. I have only 84, 85 motors so... need compatible ignition stator and cdi but the motors are in parts, boxes and I need to identify whether this stator is 84 or 85 for starters. Its an 8DZ. I have the 85 52y cdi so I'm hoping its an 85 stator and they were a pair. Also have the cdi on the 86 rolling chassis so I may run the zeeltronic cdi with the stator instead or try to get an 86 stator but want to check this out first. 1) is there a definitive location for all things RZ ignition compatibility? I had paper version years ago but cant find it... or online. 2) Anybody with experience in this swap(there's gotta be dozens).... that would be willing to chime in with knowledge, advice... I'd be very grateful. Thanks in advance... Steve

I finally found the chart with explanations and am reposting just in case someone else needs it.
The YPVS series have three different stators, rotors and CDI units
83-84 RZ350
The CDI of the first two years of construction (' 83 and ' 84) carries the marking 29 K-50. The 29K-50 CDI has a square four-fold plug, a t-shaped connector for the load coil (brown, green and red) , a two-fold plug for the Pick UP and a black ground wire. One can recognize the stator (marking ÇY) by the appearance of the load coils. This stator has a thicker coil in the center and on the right of and on the left of two smaller, which are curved like horns. The stator is marked ÇY and/or 2CY. It has two drillings and two long holes. The rotor has the marking 29L - 50
85 RZ350The 1985 31K has changed Stator and CDI. The CDI is marked 52 Y-50. The 52 Y-50 CDI has also only 8 connections (the other two to have 9). This CDI is missing the black-and-white cable, which serves to turn the engine off by the kill switch. The 85 stator is marked ÈZ or 8DX. The stator has two somewhat thicker load coils. Safe distinguisher of the 85 stator is the red-white cable at the load coil, which is always red with both other stators! A further indication is the missing connector for the "load coil", which into three individual plugs (brown, green and red-white) is divided. The Rotor has the marking 51L - 50 .86-95 RZ/RD350
The 86-95 CDI are marked 1UA - 50. The Stator looks outwardly like the ' 85 stator,but it has different plugs. A square four-fold plug, a flat connector for the load coil (brown, green and red) , a flat two-fold plug for the Pick UP and a black ground wire. The marking on the stator is 1FX. The rotor may posess the markings 1UA, -50,VCD 88,(1FY).
Combinations:The 86+ Stator functions only with the suitable rotor(VCD 8;The 86+ 1UA - 50 CDI will work without changes with a 85 31K bike. . The black white cable can remain free.
One can also use the 1UA-50 CDI with the 83/'84 31K stator(ÇY/2CY). In addition one must change the plugs going by that the cables "red" and "green" of the load coil must be exchanged . If one connects same colors, she does not function!
One can use the 85 (52Y- 50) CDI with the 84 or 86+ models. To connect an 85 cdi to an 86+ one connects the same colors and also put the black-and-white cable of the wiring harness to the black-yellow cable of the CDI. A second possibility is, black-and-white cables to the red cable to the CDI to also put (it functions both).To use an 85(52Y- 50) CDI on an 83-84 31K system you must exchange the colors red and green and put additionally the black-and-white cable of the wiring harness also to the black-yellow cable of the CDI. A second possibility is again to also put the black-and-white cable to the red cable to the CDI.
If the black-and-white cable remains free, one cannot turn the engine off
Chart Cipher:
The 84 29K- 50 CDI will work with an 84 stator and an 85 rotor.
The 85 52Y- 50 CDI will work with with the 84 rotor and 84 stator if you exchange R/Gr , S/W at S/G
The 85 52Y- 50 CDI will work with 85 rotor with 84 stator if you exchangeR/Gr , S/W at S/G
The 85 52Y- 50 CDI will work with 84 rotor with an 85 stator.
The 85 52Y- 50 CDI will work with an 86+ rotor with an 86+ Stator if you S/W at S/G
The 86+ 1UA- 50 CDI will work with an 84 rotor and an 84 stator if you exchange R/Gr .
The 86+ 1UA- 50 CDI will work with an with an 85 rotor with an 84 stator if you exchange R/Gr
The 86+ 1UA- 50 CDI will work with an 84 rotor with an 85 stator
The 86+ 1UA- 50 CDI will work with an 85 rotor and an 85 stator
The only thing I can't figure is what "S/W at S/G" stands for. Stripe?.....hmmmm
UPDATE: Thanks to some guy on RD forum
s/w = black/white
s/g = black/yellow
There is at least 3 CDI types on YPVS 350 Models:
29K-50 for 31K 83-84
52Y-50 for 57V/1JF 85-86
1UA-50 for 1WT / 1UA / 3DH1
???? for 4CE6 (RD350R).

Re: RZ350 Stator ID and swap info needed... 85 to 86
As the original autor of that comparison I may add that I didn't ride all tested combinations.
They were just tested, if they'd start and rev up.
I had a couple of people reporting that not all of the combinations would run properly.
Check out page 71-74 of my RD350 maintenance manual for the pics and comparison chart :

My advice nowadays:
Save time and get a decent programmable DC CDI that is compatible with all of the above generators, adds some 3kW of performance and doesn't cost much more that 30 years old whacky boxes.
