One for the YPVS boys (since you guys know more about them than me), as per my "wanted ad" my F2/N2 has a knackered stator, not charging and the coils are right royally shagged, so I need a new stator, of course sod's law, I have every stator for every LC, RD 250/400 A/C and 2 of the 3 possible YPVS stators, the one I don't have, is the one I need - typical !   So I've been thinking of a way round this, I have of course the 1UA-50 CDI fitted and from what I know I can't use a stator off the LC2 or F1/N1 as they are not compatible, my question is what is the issue, is it just the ignition curve etc, or is it all tied into the ECU as well/power valve control ? The reason I am asking is because I am thinking if I fit say an F1 stator and the use an ignitech programmable igntion, will this get me round any differences between the stators, or will there still be problems with the ECU/power valve control since the ignitech replaces the CDI etc. Any views/thoughts on this would be welcome, unless somebody happens to have a good stator assembly for a F2/N2 that they want to sell Thanks in advance |

You can use an earlier stator with your FII/NII CDI - you will need an earlier flywheel too though, the later flywheel won't work with an early stator.

Use this guide:
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 youexchange 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

If you are sure you have a good stator and matching flywheel but aren't sure which wires go where then just PM me or post on this thread saying what you have and I'll help out if I can  |

Having issues with my wiring. Unable to find one that fits straight into my CDI. So, worried till I get the correct one.
Wonder why Yam changed too many parameters. From one year to another, a red goes to green or a stator does not match CDI etc etc. If there were some performance enhancements or something like that, we could have understood the reason. Why these changes truly beats me.

Mark, that is exactly what I was after, I knew there was something that needed altering wiring wise, which is no biggie for me, it was just knowing which wires, I'll check that I have a flywheel but pretty sure I have a stator/flywheel combination from a 31k so that sounds like it will do the trick nicely
Will have a go at that today and post back my findings

Hopefully you will be sorted now.
All the yes stator use the same static timing so any one should work with a zeel or ignitech
Even the fixed program zeel works with them all as uses the pick up and one set of windings as is digital.

Why these changes truly beats me. I'm not an expert but the red/green wire swap is just because the load coils are wired differently .. as for all the other changes with stators and CDIs over the years then this is just progress and/or changes for emissions etc I've got a TZR250 3MA - there were four model changes in 18 months, plus SP versions too, so the 350 YPVS differences could have been a lot worse  |

4 changes in 18 months!!! Unable to comprehend. Yes, it could have been a lot worse in YPVS models!!!

Right, I got the stator working no problems as per info above by swapping the Red/grean wires around, however, my original problem was that the battery wasn't being charged, so after fitting a 31k stator and flywheel, I still had the same problem.
After looking at the wiring diagrams I can see that the regulator/rectifiers are different between the 31k and 1UA/1WT bikes, the one on the 1WT only has 4 wires, 3 white (charging wires) and a red which is the feed to the battery, the earth being via the body of the reg/rect.
The 31k has 6 wires, leaving the 3 white wires and the red wire out of it, that leaves a black (earth) and a brown (switched live), so I've done a quick wiring job and put the old style reg/rect on the bike, but I am still having charging issues, now it could be that there is another wiring mod I need to make, but if there is then I haven't been able to work it out yet
So, back to you guys who have done this, have I missed something or is it a case of my charging problem lies elsewhere?, although my old stator is knackered for sure, so I am still convinced that is the problem and fitting the right stator will solve the problem, the problem is finding a bleeding 1UA/1WT stator - part number 1UA-85510-50
Any views/thoughts welcome, or better still, a loan of a good stator just to prove that's the problem, then maybe I can work out what wiring mod's are needed for sorting the charging circuit out if yu use a 31k stator and rotor.......
