Seller Said No Mechanic Could Fix This Honda Dirt Bike

[@william6526]

When it would run for a short time and die and then after a few minutes it would do the same thing I knew it was probably the coil. The small wires inside the coil had a broken wire when it ran the coil would expand and the broken wire would separate and shut the power off ,when the bike sat for a few minutes the coil would cool off and the broken wire would make a connection and the bike would run. I had this issue back in the 70s on a 55 Chevrolet car I owned that was doing the same thing. After replacing the points,plugs ,carburetor and still having the same issue a old mechanic I knew told me to replace the coil and it ran like a top. He then explained what was going on with the coil. It never made sense to me before he explained it because every time it stopped running I checked the spark and it was fine because it only took a couple minutes for the coil to cool enough to work. I never forgot that lesson I learned as a young man .

I had a fault like that on a Russian sidecar .The carb parts made of brass would do that on a hot day .

[@brianbrooks4448]

I've worked for years as an electronics engineer and have seen this in coils in TV's and other equipment. LIke you say coils can connect when cold and then when the coil or transformer is under load and heating the wires expand and bring the fault. Those kind of intermittent faults can be the hardest to trace. You also get situations where two separate windings in the coil fuse when under load, so reduce the value/inductance value of the component and cause faults. But when tested cold and out of circuit the coil tests like it's ok. As I say, those faults can be very frustrating to deal with.

I always find it interesting that people tend to swap coils last when tracing electrical problems. The correct way to do it is start from the plug and work your way back, not the other way around. Plug, boot, wire, coil, chassis grounds, wire harness, stator, cdi. I had a 440 race chassis snowmobile with a 700efi swapped in and the suspension was so stiff that the vibrations would make it destroy a coil every season. It’s very common they shit the bed

[@jameshanna8762]

@@Slane583 Yeah, that fat spark did indicate the coil was good. My first guess was the kill switch shorting out from vibration, but that was because of personal bias. I repair PCs, and had several come in because of apparent 'thermal shutdown' under increased load, but it was actually the power switch gone bad. But the switch 'worked fine' to power the PC on, so THAT couldn't be the problem, right? However, the slight vibrations from the case fans ramping up under load would eventually cause the faulty switch to short at various intervals and power down the rig. My first check with this symptom is to unplug the power switch and short the pins on the mobo to boot the PC. The symptoms are often deceptive, so eliminating the super easy fix first has saved me many hours of pointless troubleshooting. Having known good parts to swap out is invaluable. Indeed, two is one, and one is none. I love watching the process of diagnosing these machines.

[@CLPRPSD]

@@RonaldDaub-v9y my intent wasn’t to tell anyone. I have learned that I am definitely not always right…but I just wanted to mention it, for those who might find it helpful.

I appreciate this approach greatly, but that doesn’t mean I don’t question it sometimes :)

[@METALMILITANT-j4j]

I had a similar problem many years ago on a honda dirtbike, and it was the coil causing the problem on my bike

[@runtimmytimer]

An in line spark tester would be very helpful in this situation.

[@polygaryd]

Was thinking the same thing. He should have had a timing light or something if he believed spark was dying, would have told him Right away.

[@David-jd5lp]

Yep, it was too hard to start so needed to see spark. With that you would know coil.

[@jeeplove_8831]

Grab an inline spark tester, they're very cheap but would've been absolutely priceless for this situation as you can observe what's happening to the spark while everything is still hooked up. A bad coil will typically work until it gets warm then shuts down. Great learning experience though, nice job getting it running!!

[@JEGsGarage]

I was thinking the EXACT same thing! Inline spark tester would have told the tale almost immediately.

[@jeeplove_8831]

@@JEGsGarage yeah, they're real cheap too. Stayed in the drawer for a couple years until I had an old Ford come into the shop, it would die after a couple minutes so I figured it was the coil but didn't want to throw parts at it. Remembered I had that tool and was able to confirm it instantly.

[@johnb5519]

Sometimes, in anything with windings, there could be a break or damage that when cold makes contact, but as things warm up and expand just a little, the contact is broken.

[@RonaldDaub-v9y]

He's too busy bragging on himself to understand things like that but you are correct and this guy is a grandiose beyond belief

[@Thuddster]

​@@RonaldDaub-v9y I don't see him being grandiose, never heard Joe claiming he was great or superior. He's learning as he goes, the bad coil lesson here will stick. FWIW, coil quality has been declining over the last couple decades, as copper prices have increased and more OEM and aftermarket component manufacturing has moved out from Japan, to China/Vietnam/India/etc. They tend to use slightly thinner gauge wire in the windings (as thin as they can get away with, and the coil still work) to save some costs over 1000's of units produced. That thinner wire tends to fail sooner due to vibration, and is much more vulnerable to thermal issues and overcurrent spikes. This another example of why they say "they don't make them like they used to"...because, race to the bottom (dollar).

[@2Smoke-AClae47]

​@@RonaldDaub-v9y I've never heard him bragging on himself. I do see alot of people in the comments commending him and telling him how great he is. Maybe your conflating how the people view him, vs how he sees himself. I personally find his videos to be quite inspiring. And I commend is hard work and dedication to fixing the projects he chooses to take on

[@RonaldDaub-v9y]

@@2Smoke-AClae47 that's why I know I've done this for 55 years I also do cars and I still am working. I just simply see him and making stupid mistakes most mechanics would not make and saying things like nobody could fix it except me nobody says that in the motorcycle industry that has any brains nobody is proud of themselves or should not be that all I'm saying. I see a grandiose person that can fix things with a lot of money and that's fine but he's not the god or the best maybe he's teaching you something God forbid

[@2Smoke-AClae47]

@RonaldDaub-v9y I think you may have a personal biased against him. I've watched alot of his videos, and I've never once heard him claim he was the only one to be able to fix a bike, and I don't really see him throw money at bikes. Like this one for example he used parts off a bike too see if it would fix the problem if he was made of money would not just buy brand new parts. I see tons of guys on KZbin that will buy a bike for 2500 then sink 12000 into it. Now please correct me if I'm wrong, this is purely speculation, but I get the sense your abit jealous of him. He seems quite happy doing what he's doin. It seems to be a passion project for him. I assume he has no formal training, so he just learns as he goes. You haven't presented any real evidence to back up your claim. It just seems like a trust me bro moment. It just seems kinda weird to tear a guy down for no apparent reason unless it's jealousy

[@danielparsons3995]

I never trust aftermarket electrical parts I always go to OEM and usually never have issues with faulty parts..

[@calebhohneke8482]

I never trust any aftermarket electrical part (from experience lol). You get usually one of two things that happens when you don't go OEM for electrical. 1: You get a faulty part out of the box. 2: It will work out of the box but will fail shortly down the road. When scenario 2 happens, you are left scratching your head because "There is no possible way it could be the part/s I just replaced 3 months ago" lol.

[@danielparsons3995]

@@calebhohneke8482 absolutely man it brings so much confusion to the people that don't really know, that's why it's important to go OEM or very close to it as possible otherwise you'll have people chasing their tail not understanding what's going on.

My guess is when the coil started to get warm it failed. Love the sound of those 2 stroke dirt bikes. Watching you ride with the camera brought back great memories. I'm just not used to liquid-cooled 2 strokes.

At 36:00 I was thinking loose coil ground, so I waited to see if you were going to show swapping out the coil to see if the ground screw was loose, but you didn't show it. Sketchy, open ground would explain the intermittent spark. Anyway, good work and good looking CR

Awesome video. I was thinking coil, but seeing the spark was throwing me off. You thought of so many other things I would have never know to check. Very educational.

Joe prolly won’t answer, but just to the riding community out there, can you turn a profit on older bikes like these? I don’t mean basket cases I mean bikes that run but need some work. Thanks!

[@handle690]

He could easily make $1000 or more on every one the bikes he fixes.

[@stkyfngrszmooth]

Depends on the location. I'm in New England, and you can still find older bikes that run good for cheap money if you keep your eyes open somewhat easily. With that said, these "specialty" bikes are a hard sell to everyone except the very few people who like this sort of thing, and even then, it'll take some flexibility in price.

[@michi_danksta]

Haven't watched end..I'm guessing sheared woodruff key just from the intro. Those are new renthals so I'm guessing the seller embellished what he did

Depends on location and what you buy. You can find deals but you have to know what you’re looking for and if parts are available. I don’t do it to turn a profit but purely try to break even or do it for fun

Bullshit. I've done this for 60 years and it's not just motorcycles it's everything and there is no way any mechanic worth anything would say nobody can fix anything .. I have learned over the years that anything if you want to fix it can be fixed no matter what you have to do so.

Coils can spark fine when out the bike, but they fail under load when running! Glad you got it running, it sounds wicked now!

Spark under pressure is different from outside combustion chamber in older cars very common coil packs show spark but misfire when under load plus u had strong compression probably giving false causal! Fair play to you for working it out

The cr 500 had similar problems back in the day we found valve issues and back feed to the coil. Ps you are extremely brave try to 🦵 without boot on. We stole a coil from a Kawasaki 500 and it fixed the spark issue and had a vw machine shop due the valves. Good luck bro 😎

I now believe my education is complete. I have watched a ton of your videos and the stator and the coil were the last parts I haven't seen need to be replaced to get the project running. These videos teach without ever having to have the misfortune to be in a bad spot. I knew it was an electrical problem pretty fast but once it wasn't the CDI I couldn't figure it out. The spark fooled me as well and I was lost. Joe always gets the job done.

Ran my own shop and I had known good S.P. coils, stators, and other parts sitting on a diagnostic shelf for most popular dirt bikes, sport bikes just to do the" check the easy stuff first" kind of parts swaps. Saved hours of diagnostics and lots of $$ for my clients. Simple is not always simple. Time is $$. Good job in any case. Solved the problem which is what counts in the end!
