Hey everyone, I'm David.. Retired Live in Thailand. I desided to use my old 1986 Yamaha Belle Y80 to build a Chopper. I did and it worked fine. Yes those are bicycle pedals... and yes they do work! I have since desided to change rear fork. I am using a Honda..NSR150, complete with disc brake, mono shock and an 18" much wider tire than I was using before. In doing all this I desided to clean up the wiring, as I had custom done the original as needed (quite a shambles!) I also had an issue with the CDI when it rained as water would get in it and I was peddling... So I bought both new for my Yamaha. Fantastic all wires.. I mean ALL Wires except for one.... matched up. This is my issue! Magneto on engine has 6 wires + the neutral switch wire comming out of it. Yellow Green/red stripe White/red stripe Green/red stripe Black Black/red stripe Green (+Lite Blue) Harness has these. White (=Green)=ok Yellow/red stripe (=Yellow)=ok Green/red stripe (=Green/red stripe)=ok White/red stripe =ok Black =ok Black/red stripe =ok White/blue stripe =  (+lite blue) =ok So I have a White with blue stripe, only place it seems to go is to CDI unit it's self. As the CDI has these. White/red stripe Black/white stripe Black Orange White/blue stripe Black/red stripe Green/white stripe Now I know your ging to ask me... How did the original CDI plug in? Well it had these wires. Orange Black Yellow/red stripe Black/red stripe I was told that as long as I was replacing complete harness then this would give me a better upgrade also... Was I B.S.'d?? Help me out here David Attachments:

Here's what the original Y80 belle (Yamaha) Looked like after being in storage for 12 years. I found that everytime I came back State Side and something on it failed... to save money for cigarettes or a beer they just had Mechanic cut it out....  After my wife went to market one time and she couldn't shut it off.. She finally had police come over and they closed the choke... flooded it! When she got home, I emptied gas and removed coil put gas storager in it and wrapped in plastic and stuck in shed. how to attach file here.... ? Well anyway once I find out how you will see bigggg difference fro m then to now! David |

First of all David welcome to the forum and I'm going to move this to the right section and do some studying on the wiring and we'll go from there.   JR |

So your orignal CDI was a 4 pinout, which was fed by the battery(DC CDI):  Now you say you have something like this(AC CDI).  Alleyoop |

Hi David
Outstanding
Welcome aboard
Pleased to meet you
Shes a gorgeous scoot you have done a mighty fine job with her
And JR and Alley are THE guru's when it comes to solving electrical problems, your in very good hands here
Take care and ride safely

Okay Thanks everyone! CDI is Yamaha, it is same as the one in my wifes Yamaha 111D Mate Super. She won't let me take the covers off hers until I get mine running  Can't blame her, really I had cut and spliced the original harness to fit as I was in process of welding and designing original frame I ended with. Other then the Motor being completely gone thru (Brored, Stroked, Polished and Ported) it is used for low/midrange cruising. Until I find another 111D Mate Super Complete engine (w/electric Start... which will fit and solve this issue...) I wil be using my pride and joy (engine it's now between 97 - 109 cc and HP??? I only guess as it strong up to 8000 rpm and great mileage! I can almost go from Chiang Mai to Bangkok on one tank (745 Km's) ... tank is 12-14 liters depending on how full is full!  Okay back to business... Bike has been converted from 6V to 12V, this was done with adding Rectifier/regulator and changing Battery and bulbs to 12V. I have balked on switching Stator out as I would preferr to add Electric start 111D Mate Super instead. I chose this model being a 1996 because it will match my wife's. and it has a flywheel driven fan that sucks air in and accross head ...like Suzuki did. I don't know how much I can do to block and head as I clean up and rebuild before I bolt it in frame. But for now I have an issue... Original Stator wiring is as follows: Source Coil Black/red stripe Black Day Lighting green black Night Lighting green/red stripe black Charging Yellow Black CDI Coil White/Red stripe black Now I just noticed that the CDI coil has the black soldered into the rest of the grounds. In my other hand I have a failed sample of a 12 Stator complete. (does not have the White/blue stripe wire)  darn it! but it uses white/red stripe and a green/white stripe on same coil. and other then it having an extra coil (were 6V uses 1 but divided into 3 parts) the wiring is pretty much the same. Oh! The CDI you showed in picture is Honda. Yamaha has little black box with one side a mounting tab hole and oposite end has lead with wires exiting and sealed with black... silicone?? Yamaha built this in a 50cc, 80cc, 90cc, 100cc, 110cc, 111cc, 125cc etc. |

JR If I could find a diagram for a Yamaha 111D Mate Super, it would answer questions as this model (1996) has this CDI on it (I did get to see that much before she told me to leave her Yamaha... ALONE! (shes afraid I will customize it also ... ) |

OK I haven't given up on this and I think I'm sure I have your answer. A lot of the old model scooters have this and since you're mixing a 6 volt stator to a 12 volt ignition system you're not matching up: Here is a picture of a 96 Yamaha YZ85 coil, CDI and pulse or pickup coil:  You can count the wires and do you see what I see? Nearly all modern day scooters have only one wire from the pick up coil. The coil is grounded at the mount base and only one single pulse signal wire goes to the CDI. But in this case they have two wires which both go to the CDI. Most DCI's have two pins that are designated as a ground. I'm saying you're extra wire is for the pulse or what we call the pick up coil. Your old CDI has 4 wires: Orange = power feed to the coil Black = ground black/red = AC power feed to CDI yellow/red = pulse signal wire. So the question is can you make the CDI work on the single feed wire to it? JR |

JR I think I found the answer here in Chiang Mai. Digging thru a pile of Stator Plates, Complete with coils. Here is what I found: The ones that had the White with blue stripe wire were as follows. CDI has (in my harness and CDI) two leads to feed Coil 1 - White/red stripe + 2 - White/blue stripe = Ground CDI coil and CDI Control. 3 - Black/red stripe + 4 - Black = Ground Source Coil 5 - White + 4 - Black = Ground Charging Coil 6 - Yellow + 6 - Yellow/Red stripe Lighting Coil 7 - White/green stripe + 4 - Black = Ground 2nd charging Coil Even thu stator has a black ground wire already that feeds all coils. Except it does not feed the ground to CDI circuit. So the correct placement for this wire is at the CDI coil with the White/red stripe. I have already fired Bike up... very hot spark! Best arc and visual of arc I have ever had. Also as I have left bike is with white/red stripe and white/blue stripe the only wires at CDI Coil. For information purposes it also will fire with same arc when I jump white/blue stripe to Black at Stator. Doesn'r seem to matter. I just left it as I found these other stators wired  JR Thanks for your help! also any more input as I build will be welcomed. As end result this bike will have a 150cc 4 stroke Honda air cooled engine. We have made new bottom section of frame a little different as I have made new Yamaha engine mounting that is removable, it bolts to Honda mounts and lets us offset either engine for use with wide rear tire. As the original was built as a "Hard Tail" I am using a Honda rear fork from a "Honda NSR150" assembly is complete mono shock, disc Brake. I have overcome brake wireing issues as I installed 2 new brake hoses, one @ front Master cylinder the other at rear. these have builtin pressure switches to activate brake light. This also let me relocated rear master cylinder farther forward and was able to machine new linkage for relocated brake pedal!  Again thanks for your valuable input here. If you are interested, I can post Pictures as the build is transformed and completed. (This whole Idea got started to show Ministery of Transportation here how it was possible to recycle. either as a used Motorcycle or as a Motorized Bicycle. Thus as Bicycle giving families a 2nd petrol powered vehicle. This one would fall into the bicycle forum and not require any Licenses to operate. We have left the option open here also but will move the dual (stacked sprocket to left side of bike) sprockets if decided to push this issue. Regards David |

Regards David You confirmed just what I found, no need to post a picture because I also found a stator that did confirm the two wire pulse coil and the place to put it on the CDI. This has been a very entertaining thread and educational also by all means post your pictures and updates along with info. This is how we learn! JR |
