- Yamaha Moto4 wire harness decode, using a pit bike CDI, the engine, harness, and CDI, what they are for, and where they go, how to hook up a pit bike CDI to proved spark, no guarantee on how well it will work, how long it will last, Harvey Spooner, Hoarding Mayhem,
Boss man I just want to thank you sincerely for this. I've had a badger 80 with a bad cdi for years and is now running again thanks to your video. Thank you for the wiring info
Thank you! For me it was about a week of me breaking down and refurbishing my 85 moto 4. Wouldn't spark, went through all the wires, starter, solenoid, get to the ignition coil and boom my ground wire from the harness was just taped in place, not connected to anything! The coil was brand new so I didnt even think to check the connections until I saw this! So again, thank you!
God bless you man! After a few long days, managed to start my 86 Badger. I was connecting the wires on my CDI unit wrongfully. Thanks a lot for this video!
I''d never guessed it was a yamaha. Replaced the cdi on my father in law's g9 yamaha golfcart. 148 bux. If it would have been mine I would have tried the china cdi. Thanks for the yamaha wire color code breakout. Now if I ever run across one I can reference this video. Have a great evening!
FYI. I just rewired my Moto4 with a Chinese CDI and I had to wire one side of the trigger coil to ground and one side of the HV coil to ground. And I had to trial/error swap which side was ground to get a strong spark. But it runs great now!
How long did your cdi last
@@bryceknue6244 still running fine.
So in the end did you connect both of those to ground, or only one?
great to see you helping people out with these ignition systems. I had to figure mine on my atc200s all out on my own without any references back in 2010 or 2011 and it really frustrated me at that time.
Harvey hope you are still answering questions. Got an 1985 moto 4 80 I believe can you swap cylinder heads with a bigger one with no machining involved also great instructional video i like your terminology helps alot.
I learned more from u in 6 mins then the last month and a half watching other vids that relate but not wat im looking for
Your helpful to many. Thank you. We all love this. I do anyway.
Hey Calvin!!!! Deer season up down by U yet??? I'm hoping to keep as many of these Honda ATVs and ATCs out of the scrap yard as possible, Thanks for all of Ur kind words, encouragement, support, watching, and commenting!!
Calvin's Corner72 that's a Yamaha 3-wheeler right
Trying to get my 84 moto 4 200 to charge it’s own battery when running like it should. Bought it from a guy who did some funky wiring...
Could you please do a video on how to wire a DC cdi box into a 87-88 moto4 350? Please!
Can you do a video on the earlier moto4 with 2 pulse generators?
I know the green wire is most of the time the ground . But on some red hot coils it is the hot side. I had a gy6qmb and put a red hot coil in it and it did not run .
Harvey, the CDI for the moto 4 should be an A/C CDI correct? The stator is actually creating the power to power the coil. Thanks!
Hey Robert, If the quad, trike, or cycle will produce 12VDC, I like to use the DC version of the portable CDI box... But, U R right, the moto 4 coil should produce the ac power necessary to run the ac cdi system.... Thanks for asking, watching, and commenting!
Thanx Harvey!
Thanks man!
I have a1984 Yamaha wires been cut what does the the insulated white wire go to the 3 coming out of the side of the moror
i could use some help ole wise one i have a 87 lt230e Suzuki quad runner the CDI has a cold solder joint i think i have a vice clamp on it and remounted where i can smack it if it cuts out . a new or used one cost a lot any tips on a good cdi i can swap out i ordered a dc cdi for a "250- somthing but have not tried it out . not even shore if my cdi is ac or dc lol
Hey what happened with this? I got a 85 230s. Cdi wires been cut down to 1 inch nubs and wire harness is gone.
@@KevinBeGood it runs good took 12v from the battery 1 wire from trigger to cdi one to ground then from cdi to coil
I got no voltage from the red/black wire to power the cdi. It failed the the test in the clymer manual for checking connection between the red/black wire from the igniter coil to the single black wire that goes to ground on the stator. The other coils pass their own described tests listed.
I have a motor 4 Yamaha 350 not getting any spark at all been trying to fix about a month straight got it to spin over
Can a wrong size of spark plug cause no start??? Theres a little faint spark but dont want to start looked up spark plug and its the wong one ..
Hi I have a Chinese clone of a Honda cbx 250 two cylinder, I have the same cdi unit, but I got two coils, how do I set up the second coil? Do I just split the wiring so that it runs to both coils (wasted spark system) or do I need a different cdi unit or something? Please someone let me know, I can't really find information about this anywhere.
Thanks!
mine has 2 you ever figure how to wire them?
Wiring it in like this will it still charge battery ?
i put the pit bike harness and dc cdi on my yamaha moto 4, it runs but when i rev it up it just misses and backfires terribly. any idea why its doing that? i had no problems before revving up
Hey StorminNormanZ , Reverse the wires on Ur pulse generator.... Yamaha ATVs typically have 2 wires going to their pulse generators, just swap them and see what happens.... Let me know.... Thanks for asking, watching, and commenting!!!
@@HarveySpooner thank you man! Mine actually has 3 but I'll try reversing them. Thanks so much for the help
Mine has a yellow wire a brown wire an white/red wire and white/blue and the ground
I have a 87-89 yamaha moto4 250... will not start. Can crank it by shorting the starter solenoid. Can you help?
@ Harvey Spooner can this be done to a 2 coil stator?
Hello, very great videos! Thank you! I have another question for you. I have a 87 Yamaha 350 big bear, and can find cdis only for a few years newer, 90-94 and 95-96. Would it not be possible to eliminate your "switch safeties and extras" that run into the CDI and just connect the trigger, power and ground connections to make a newer unit run on an older version? The connectors are mostly the same, and most of the safeties are the same however a few colors are different. My bike seems to have a slightly different wiring layout, that im not fully capable of understanding staring at both schematics. And on the same token, couldn't one make any CDI work with just bare bones connections?
My moto 4's cdi is a 6 pin, the bike is only a 4 pin, it came with 2 slots wired into each other with a short little baby wire.
Woah, my names Sean, my wife is Kaitlyn....if you had a daughter named anna or lilly it would be more than freaky haha
Hey Harvey, I was wondering if you'd have a starter motor and wire harness for a Yamaha 225 trimoto?
Hey Alfonso, Where R U located, generally speaking, I do not sell parts, too much grief and too time consuming... About the 225, I would rather pull the forks and tires and sell or use the drive chain else where, parting out the ignition and started stops me from both possibilities... Thanks for asking, watching, and commenting!!!
What do you hook the blue neutral wire to?
So what
Did you do with the blue and white ?
Got 1980 Yamaha sr250 motorcycle no wiring harness will this AC cdi work. going to be used for racing . Spark only. No lights,horn ect.
Did you figure out the answer? Im in the process of installing a engine from 1981 Yamaha sr250 only to find out the cdi is actually a tci ignition with ridiculous replacement price. Hope to find a cheaper option but havent found much.
I have well what was sold to me as a 250 4stroke. Well the kill switch melted. It has 11 coil stator and 3 yellow wire stator. I need help asap. Please if anyone has any advive please help. I havent road this 4 wheeler in 3 years
Is this an AC cdi box or DC?
Is that a Yamaha 3-wheeler
Hello
My motor doesn't have the black and red wires
Does it have an stator? There should me 3 wires coming out of your engine, two for power and one for the trigger signal (blue&white) you can check under your flywheel cover, the trigger wire is attached to another separate coil than the other two wires.
