Hello all, just joined up and have a question i am hoping someone can help me with, i have painstakingly been rebuilding a box of bits 350 YPVS on a 82-84 plate, shes nearly complete now but I can not get a spark, i have eliminated the silly ignition switches and kill switches and the stator with an ohms check and replaced the coil still no spark, must be the CDI box, does anybody know where to source one from or a quality after market

Hi bud it might not be cdi, are the rotor, stator, cdi matching numbers? If rebuilding from parts they might not be if they ard not it wont spark im not sure which number work with others someone will be along shortly or do a search here there was a posting a whild back showing compatability

Hi Adie,
Oh NO I have no idea I'm like most I hate electrics, there were two stators in the box's might be worth while swapping them over and seeing if I get any joy when I get home, I did compare the two with the ohm meter and did get slightly different readings but put it down to age and condition, any idea where I find the numbers on the stator?
Cheers Andy

Type in rdlc crazy into google then click on lc history in the top banner scroll down to ypvs and you'll find all the info you need

Best thing to do is post photos of what you've got - far better than guessing yourself Copied from the thread on stator/flywheel/CDI combinations: 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 88);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 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 The only thing I can't figure is what "S/W at S/G" stands for. Stripe?.....hmmmm 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

Thanks for everyone's assistance, I have checked through and sure enough I have a complete miss match of bits, thanks to the last post I have realised that I can match the spare stator and the CDI box on the bike as 1986, just waiting on the delivery of the flywheel puller so I can swap the stators over, can't wait to see if it works, I will keep you posted as to my progress, puller should be here tomorrow ? Many thanks

Oh dear, very very disappointed no joy at all, that elusive spark is driving me crazy!!! So this is what I have in place; 52Y-50 CDI box 8 wire Rotor reads 29L-50 032000 - 3441 6DZ Stator plate is again 8 wire with the red and white wire
PLEASE HELP I'm on the verge of a mental breakdown with this one, is the answer to junk it all for an aftermarket one and if so where do I get one

You have: 85 stator 84 flywheel 85 CDI The chart says: The 85 52Y- 50 CDI will work with 84 rotor with an 85 stator. So you certainly should be ok. My advice would be to go through the stator tests again with a multimeter - you do know that some tests only register correctly if the engine is turning over fairly quickly, spark plugs out but earthed (tape them together), and half a dozen quick, hard kicks? Just to give you the added confidence you really need right now, I went through all the tests on my 350N over and over again and they were always within what they should be but the bike had a weak spark and refused to run. I ended up getting the stator rewound and buying Banshee coils and a Zeel from Norbo .. starts first kick every time now

Cheers all for your inputs, Yeah tried swapping the red and green still no joy, I put all new connectors on just incase there was a bad connection, from what I can make out all of the readings are within the tolerances so I can only now put it down to the CDI box being knackered I recon, you mentioned buying parts off Norbo? Will it set me back much for coils and box? How do I get in contact Thanks for all of the help, really glad I found this site everyone is like minded and helpful, keep up the good work
