You are such a good teacher Kevin. I am so glad I found you. I have been struggling with fixing my vintage bikes for many years and your video is going to be my break through. Thank you.
Very welcome happy to help
Thanks for making these videos! I recently picked up a non running 78 ke100, I replaced the coil, plug, points and condenser, still had no spark. I watched this and couple other of your videos and figured out a few things I didnt set up right. I think the main thing was I did a bad job soldering the wires on the condenser. Now I have spark and the bike is a lot closer to running.
Great video Kevin!! The most important part of your video is at the 10:40 mark when you explained the book says primary and secondary coil. Which can easily be confused with the two windings in the Ignition coil.
Exactly
Good job Kevin I learned everything I need to know thanks
Glad to know im not the only one who has a hard time removing old condensor solder...
Old soldier is awful to melt
Dear Kevin, Great tutorial. But... I am testing a 1972 yamaha 100 enduro lt2. No spark condition. Replaced coil, spark plugs, rectifier. points, condenser... etc. I have 3 coils in this stator. One is the source coil, one is the charging coil and one is the lighting coil. This vintage bike is 6V and has one set of points and one condenser. The points are connected to the condenser with a blue wire and 2 of the coils are connected to the condenser. So 3 wires are soldered to the condenser. The condenser is bolted to the stator plate obviously. The black wire coming out of the stator wire loom about 15 inches from the stator is connected to the orange wire coming off the main coil (primary coil input) up above under the gas tank. It does not have 2 wires coming off that coil... just one. I guess the ground to the coil is through the 2 bolts to the frame. The black wire (coming out of the stator wire loom) is evidently also looping/going up to the headlight area where there is a rat nest of wires on this old bike. I am not sure if this area has the black wire hooked up properly as my son disconnected some wires while replacing the headlamp. I assume that when the key switch is in the OFF position it's acting as a Kill switch. Key off... coil is grounded. Key in position II or III the wire is not grounded anymore... so coil/spark plug should work. I have run all the stator tests for resistance and such. Pretty sure all tests pass... but the wires running to the condenser are giving me grief. Even put a piece of cardboard between the points but still get resistance readings. I have taken the coils off and tested them as well. Getting resistance readings. I cannot test the coils on the stator plate because of the condenser bolted to the stator plate. I've tried many, many tests. I'm so confused at this point. I am going to assume the new points, new condenser and 3 coils are good at this point. NOW... To make sure I am bypassing any incorrectly plugged in wires behind the head light... I am wondering if I jump ( 5 inch piece of wire) the black wire (coming out of the stator wire loom) directly to the main coil under the gas tank (orange wire into the primary windings of the coil)... if I "will get" or "should get spark". Help! Thx BQ -
1st start with new points and condenser and spark plug this is always step 1 if you brought this bike to any shop they would say let's start with a tune up
Excellent video! I’m in the process of putting my 74 g4 back together no spark, I haven’t touched a points system machine in probably 15 years haha thanks so much !
Top man, did as you suggested my bike which has been a nightmare is now working, and new points were like yours not connecting till I cleaned them, keep up the good work Kev 👍👍
Very detailed and spot on, well explained 🍻🍻
Happy to help
Just finished watching your KE100 CDI to 12 volt conversion videos. Interesting.
Awesome video! I wish you were my neighbor lol. Don't apologize for the length, its a lot of super helpful info. Now to get my 1970 Bushmaster (I think) running.
Thank you
Very good video. Exactly what I needed to know. Thank you Kevin.
Welcome
Thank you! I have watched many of your videos and studied them! Thank you!
Very welcome
Great video! Covered everything I was looking for. Nice job and Thanks!
Welcome
Thank you so much sir for this video. I try this for my KH 100. God bless
Welcome
That's helpful thank you for teaching ☺️☺️
Ya know I like the way you do things! Old school like me
Great video I have learnt alot ! Thanks 🎉
This video is just what I needed, thank you!
Very welcome
Hey Kevin , what an awesome indepth video on the points magneto system , I got a none sparking 1972 yamaha lt2 100 American import here in the UK , and now I no how to test , find , and replace any of the suspected items in the system , I got a manual , but a step by step video is so much better , I'm so glad I found you and have now subscribed to your channel , top guy is our kev , 😀 👍🛵
Thank you happy to help
Sorry about my ignorance but I have a honda xr 75 with one wire and a little black ring with a gold spring on the bottom right is this my pickup point by the way I want to tank you for sharing your knowledge out of many the way you explain stick in my mind easy tanks again my friend
Text me pictures 603 395 8097 very welcome
Amazing video, I've gone down a rabbit hole watching your videos on ignition components and will be referring back to this one tomorrow when I attempt to do the same process to my 1980 yamaha DT100 :)
Will let you know how it goes!
Amazing video and explanation!
Thank you
Can I ask what happens if no condenser my bike run bad if I install one??
Really did a great job. Thank you, thank you. Great moderating and picture quality. Do most of the early 70's points minibikes use the same points and solder type condensers? Thanks
Very interesting... keep updating us please!!!
Thanks. You asked for it so here you have it :D ;
I have the same style Bosch system in a 2 wheel tractor with a long time legacy 1 cyl engine from the late 1950´s. From what I can find when searching part read Bosch numbers, I find various Vespa and others mopeds + 125ccm´s with multitudes of charge coil outputs. Mine has a measly 12V 12w charge output, cant power diddle. I´d like to upgrade it a lot and upgrade to electronic spark while at it. How much does the physical geometries/physics of spool plate and flywheel/magnet strength compabilities variate to these ? Chef´s thing, or is it very picky ? Is there fits all soultions offered?
Sir I just bought a 1972 lt2 and I have a good spark by inginition coil but the spark on spark plug so poor already tried different inginition coil but keep same problem
I like the back to back videos kevin.
Thanks
Hey Kevin. Thanks again for the videos they great. I have a question I am trying to get my km100 started it has a new bored cylinder I have set the point a bunch of times but still get the same results . The bike just pops or stumbles for a second then floods. It only floods after a couple of kicks. The plug is wet with fuel. Do you think it’s a timing issue? I have good spark but it just doesn’t burn in the cylinder.
Call me 603 395 8097
Thank you so much for your help. I finally got the km100 started. It’s wierd. My gap ended up being .004 of an inch. I tried .013 and .012 and it still would just flood. I ended up disconnecting the wire off the points and gapping it so that when the timing mark matched up it was a break in my multimeter. And it worked. Would you know why my signals don’t flash? When I turn them on they just get brighter. Also the neutral light dosnt work and my high beam light turns on when the low beam is on and turns off when the high beam turns on. Thanks again for all your videos I would not have gotten this bike together with out your help.
Great video!!!! Well done!!
Thank you
Is it normal for my black wire coming out of the magneto to be grounded to the magneto plate? If not what could be the issue, i have checked the points and they are working correctly, my condensor is also not grounded either
Great informative channel! I’ve learned a lot about my newly acquired ‘74 KE100. The previous owner replaced the capacitor and points. Bike ran great for a while then started acting up and not starting. I found that the blue wire was incorrectly routed and wore thru because it was in contact with flywheel. I fixed break and reassembled. Zero spark now. Going to go back in a check a few things I learned from you. What’s the correct way to route the blue wire? Does it go behind coil plate?
No infront
That's awesome great bike
What Wires Go To The Condenser? I Can See One Going To The Points, But Where Do The Other 2 Go, And Which Wires Are Attached to One Another?
13:45 ... it says on the manual 0.5 ohms , not 5 ohms . 15:20 ... first of , you're setting the multi at 20k ohms when it should be at 200 ohms which you should get around 0.2 ohms . For continuity test you should place the multi just on the left position of the 200k .
Yes I know I forgot to say. 5
Hi Kevin,
I am getting 2.7ohms at stator, manual says approximately 0.5ohms? Does this mean I need to replace it?
Getting no visible spark at the spark plug, but get shocked when I touch it 😂. Have followed your videos multiple times the only test I’m not sure of is the primary coil resistance?
Yes high resistance
Great video
Thank you
where can I buy a stator plate with coils for a 1972 Suzuki TC 125 plus new flywheel
Ebay or Rick's motorcycle
Thank you@@2strokeguru
so i'm trying to repair a yamaha gt 50 for my father current and main issue outside tank full of gunk is no spark. The spark plug is fine, spark plug cap(had to be replaced no continuity), ignition coil(has correct ohms reading 6.4) and has continuity to the spark plug cap so its fine), the condenser seem to be charging and discharging with the multimeter so its also good, rectifier is busted but its not an issue to get spark i guess, so my guess now is stator or maybe a short somewhere, but thing is i saw a spark once or twice but out of 50 tries or more so shoudn't be a short i would like an expert opinion on if the stator might be the cause. Update out of the stator is coming max 5V with the kickstarter, idk if it correct to test the ohms of the coil like this but from the black wire to ground i get 1.4 ohms factory says 1.3+- 10% so its in range
Great video's man! Very informative.
Thanks I try hope it helps
ok you asked for it... how do you test it.. example l don't understand that it all goes to ground, when l open and close the points there's still a circuit to eath / ground.. why ?
Kevin, I have the same manual and under the Magneto Ignition Coil section, mine reads "If the resistance is approximately 0.5 ohm, the coil is good." Not 5 ohms. But to your point, since it says "approximately," that implies a range, rather than exactly 0.5 ohms.
5 or under is good there's a couple reasons for approximately electrical parts wear and meters are not all calibrated the same
I have 1 that's good and 6 ohms
@@2strokeguru Understood. I will focus on replacing the points.
Kevin, I replaced the points and condenser. I have spark, but it isn't consistent or often enough. When I kick it, it sparks a few times, not constantly like it should. I tried to start the bike and all I get is a backfire every once in a while. Any ideas?
@@matbogbrygmail740 it sounds like the when you set the points it was not properly resting on the cam so its firing during the stroke rest the points
Yes
I have a 1980 kz440 with no spark and my points plate doesn't have any coils on it. My stator on the other side of the bike does but the manual said it doesn't effect a no spark situation. I've already replaced and tested the points plate, points, condenser, and main coil plug wires. Any advice would be great.
It could be a couple things neutral safety switch if the bike has a kickstand switch or a faulty handle bar kill switch
@@2strokeguru yeah I checked that. doesn't have a neutral safety switch. checked out the start stop kill switch numerous times. Im going to just have to spend time on it I don't have. thanks for the advice though
hi can you help me.i have suzuki f70 the light machine have 4 cable blue green black and yellow.the blue is outside near the wheel.where have to doing the other 3 cable
When I open the point, the light still come on. What do you think the problem is?
30:15 i never knew anything about that man 😭
Hi master
I have kawa 100 g7t
Engine is like ke100
How can i change point to cdi
Without change magnet
Older engines unfortunately have a different taper too the crankshaft so the flywheel will not be interchangeable send me pics of your bike 603 395 8097
Hi again, thanks for your reply. Sorry to hassle but I meant how is the condenser wired to the winding? My ignition winding only has one wire coming off it and that is going straight to the ignition coil. Thanks again for your help
I did that in my other ignition videos check out Aaron's bike build its really i show the whole thing
I did the test you showed with the paper in between the points and I’m getting the same reading of 0.00 with the points open or closed. What does that mean?
Points are not making contact Points are bad
@@2strokeguru there new points
@@falgianibrandon new points can be bad if they don't ground and have the same reading open and closed either they are bad or the leads to the multi meter are bad touch the wires together make sure your meter is reading
@@2strokeguru I just tested the points off the stator plate and work fine I go to put them back on and I’m the same 0.00 reading weather they are open or closed. It’s very frustrating lol
Asked this on another video. But how clean does the surface of the cam have to be? Bright shiny with emery cloth? We are not getting a spark yesterday. I think it's the exciting coil, but i will check out again. Good video for bike newbies.
I have 1980 kawasaki ke 100 that was a barn find and had to put points condenser and coil and would not start by kicking over, but will start if I pull start with my atv and keep revving up rpms and when you let it idle it dies with in five minutes ?
Hey Kevin, I need some help with my 1973 Kawasaki G5 100. It will only run for about 10 minutes and then shuts off and won’t start, and when I try to start it makes a popping sound out of the exhaust. Do you know what I can do to fix it?
Try a new spark plug that one sounds fouled
I’ve replaced it 3 times already. Could it be the condenser? When it’s running the point sparks a good bit.
@@iderzian6565 yes it could be points and condenser absolutely
Will the strength of the magnets or lack of, effect the voltage from the coils
Magnet strength is what makes the field in 30years never seen on lose strength and 12volt and 6volt have same strength
I would be interested in knowing in that video which wire goes where work comes from what and goes where
💥🏍Hi, Sir as you said ask anything 😁I have a 2000 Kawasaki 1500cc Vulcan Classic…You see that Dwell Meter you have, how can I check the idle on my bike or any 🏍so it can be set to 1000rpms with out using the motorcycle tach-gage?🤔💥
Your bike has cdi ignition dwell is only for points ignition
I have a quick question In regards to my two coils for charging the battery I have one that has large copper coilings and one has smaller Coilings on it. Will this set up charge my battery and run my turn signals or do I i need both coils to match? Working on a 1976 km100.
Is the primary coil supposed to be grounded mine is and its making the points always be grounded....the points should only be grounded when they are closed right ? It's got me stumped
I have a need for the lamp and ignition coils for a 66 Honda 50 cub. I have tried the usual suspects for replacement coils to no avail and wires are too small for rewind shops. Do you have a go to supplier for vintage coils?
does anyone have information on spec of point gap and top dead center for Kawasaki J1? Thanks
Great explanations.absolutely Newbie to bikes and magnetos.on my 78 suzuki ts125 i get no spark.there is always continuity no matter if points are open or close. Points itself seem to work ok.is that normal?what can i try.change condenser?thx
Where can I get a set of points and the condenser I have a 1974 kh100 but trying to find parts for it
ebay.com / partszilla.com
How does the condenser attach to the coil? I know it’s held by a single screw. But how is it wired to it?thanks for your help.
Yes single screw
It's wired from the non grounded part of the coil, and the points, and the third is what runs up through your harness.
Hi Kevin. I got spark from my Kawasaki j1 ignition coil wire but no spark when I connect it to the spark plug. Can you help me with what the problem might be? Thanks
The spark plug is new by the way.
Hey Kevin I'm trying to build this Honda xl-100 1979 is there anything else out there that will fit that bike Magneto points
Check xl 80
I have a 1985 k e100 and my points aren't opening what could be the cause of this? And how do I fix it?
Do you have the flywheel on it
Yes I figured it out I tightened the Phillips screw that is right above the points
LOL I don't understand why it started working
Can the stater be changed out from a two coil to 8 or 6 coil. Is that possible. My dirt bike has a two coil but the flywheel I ordered online is for a 8 coil stater.
Hi Kevin. Will your coil (primary or secondary) testing procedures work on various wound coils from other bikes/models regardless if they use points or CDI? I just followed much of your idea's and was able to get a '79 Suzuki DS100 running for a guy that sat for years and years. Also waiting on points and condenser to arrive for a 1980 KDX80. Thanks for all your info.
Hi Kevin, I’ve been working on my ‘71 Kawasaki F6 timing. I can’t seem to get the points to open when moving the flywheel. the bike has 10,000 miles and was not running when i bought it though it does spark with the plug touching the outside of the jug. have you ever heard of the flywheel cam wearing down so much that it doesn’t open the breaker points? thanks very much - love your videos!
After coming to the conclusion, the exciting coil is possibly open (the ad on kijiji stated "no spark") I decided to sent the coil out to be rewound in the USA. Last look on Ebay a week ago, a gentleman in Quebec was selling the stator assembly and magneto off a 1981 KE100. Received it this past Sunday. Canada Post is working OT for Christmas. Never had to set the points ...nada. Installed it on the bike and got a spark. Is the output limited to 6 volts max from the lighting coils? We need a new lights and speedometer. We do not have a 6 volt regulator. Could we use a 12 volt regulator?
the CDI is built into the coil
Its is the same? on how to test G7E ?
Hey Kev. I lost the square of felt that oils the magneto cam. What works instead? I bought it off Ebay (expensive) and lost it on my workbench. It's so tiny...
Craft store felt will work
And look it up for a Honda like a cb350 any Honda points bike it's the same and cheaper
@@2strokeguru thanks kev
@@CrimsonYetiCartoons welcome
cigarette butt !
Hi kev have you got a primary coil you would sell me and post to the uk? Mines putting out 2.7 ohms 😢
What manual are you referencing in the video. it's different the service manual I found on line for the KE100.
I use clymer and Haynes
thanks good video
Hi Kevin, I've got a 1979 suzuki ts 185 er ,but no spark can u please tell me how or if I can test the c.d. ignition unit. Thanks
send me pic of the magneto and ignition coil
That's amazing. Weird.
does a flywheel have to be matched to a stator plate or can the two be different ?
Yes 4 magnet for cdi 3 magnet for points
Any idea what is going on here please ? Yamaha dt 100
Damm cannot add the photo
Can I check the points when it's on coil plate? With wire attached on it?
I just did a video on this hope it helps
Hey kevin I have a 1999 kawaski ke100 and it has a really high idol i just bought it and the person disconnected the oil jection idk what it could be any help would be appreciated
Its sucking air lean condition keep the automatic oiler the engine is going to burn up
The engine is sucking air
Your going to destroy the engine reconnect the automatic oiler Your rotary value needs it
Ok this is my first bike and I've never had a 2 stroke so idk know anything
@@colby.b8438 that's ok im here to help
Make your mind up, it’s either open circuit or short circuit, not both! In this case it’s open circuit!
When the points close its a short When the points open its open circuit points are nothing more than a high speed switch so both
@@2strokeguru Without the cam which is in the flywheel the points would be closed and so the black wire would have read short to earth, with the points open assuming the condenser is not short it should read a couple of ohms through the coil winding.
Hi Kevin,
I have 2 bikes and believe or not both is not firing cause off the 6 V magneto issues On my Honda Trail 55 I was getting spark on the Green wire ( believe it is for Ground ) so took a part and Lighting coil has open so I order a replacement 6 V set for Honda ( couldn't find specific for Traill 55) when it arrive my original has 3 wire new one has 4. What is the 4 wire on ^ volt coil does and can I bundle it with ? one of the other except the ground
I will more then happy to pay for your time and effort If you can help me out . You can text if that is OK so not only I can contribute to your cannel also we can share a pictures and visual help let me know so I can send you my cell number

When trying to test the stator I get a reading of 2.0 ohms does that mean I need a new stator
The motorcycle runs but dies after ab 10 min of riding btw
It’s a 76 km100
Sounds like points and condenser 2ohms is good
@@2strokeguru ok thankyou very much I’ll let you know how it goes ordering parts now
@@connorbeck6191 awesome I have videos on it
Uhmm, that reading is showing in the book one half of an ohm not 5 ohms. Using an volt ohm meter improperly will not help when diagnosing, just saying. Also, you are on the wrong scale to read low ohms, you have it set on the 20k or 20,000 ohm scale in other words. You can't read accurately anything down at a .5 ohms.
Yes I messed up
I did everything & still no spark 😢
Something has to be bad
@@2strokeguru the tab that holds the wire onto the condenser came off & I soldered it back on, but it looks fine. Could that be my issue?
christ you dont use the tabs on the condensor and stick a terminal on its soldered for christ sake read the book
Yes in fact I do relax this unit was from my junk pile
