Yamaha TTR 125 Dirt Bike Shuts Off While Riding...Won't Start Up

[@markhensley9378]

Even though you're doing it for free I still appreciate you taking the time to share this repair with us. I'm learning how to get this done and expect to have to do it myself sometime. Thanks again for your time today.

I like your videos, you are one of those guys that doesn't begg for subs and sell super expensive merch and get all annoying and crap but you're down to earth like some others like mustie1! And you're young that's so rare to see a young man down to earth unlike most KZbinrs. Thank you for the great videos ❤️

Hey joe, you should consider picking up a hydraulic press, two dial indicators and an assortment of v blocks. I've heard you mention it in the past. When I finally broke down and decided to get that equipment, it was the best decision I ever made! Being able to rebuild a crank yourself, on your own time with no added expense truly is a game changer. I guarantee you will be hooked! Keep the videos coming.

[@calebwilhelm528]

To help find the VIN scratch of the paint and take some vinegar and salt to rust the frame. That might reveal the outline of the numbers. That's how my Honda is, it has the VIN plate and it etched into the frame. The numbers that are etched into the framed are rusted on the edges and it makes it really easy to see them. So maybe try the rust trick. Love the videos Joe keep it up!

Great content - Yamaha TTR's are iconic at this point, especially TTR 125's. Most everyone who rides either started on a TTR of some sort or size or had a friend that had one when they were learning to ride. NOTHING wrong with low compression, low maintenance, air cooled 4-stroke bikes that are normally bullet proof for a lifetime (unless you run them dry of oil).

[@frdmstnggt99]

I picked up a 2003 TTR125-LE for $500 pre-COVID with a locked up engine. Turned into a huge project. Needed new cases due to stripped holes and a new main trans shaft. These machines are known for stripping out first gear. Got it going but for more $$$ than it’s worth.

[@chumps7974]

I've never heard of them stripping first gear. They're pretty solid if you take care if them. I'm sure you'll get your money's worth over time.

[@MyBoyzToyz]

when trying to diagnose the noise and location I always use a solid piece of wood, put it against different parts of the motor and the other end to your ear and use it like a stethoscope. Sounds daft but really works.

I'm glad I found your channel. You provide great information and I really enjoy watching you work through problems. Just out of curiosity, why don't you use a washer in a pair of vise grips to remove stuck plugs rather than a screwdriver and hammer?

[@AlecGD]

TTR 125’s are awesome if they are well maintained.. I’ve rebuilt a few of them that were not including a seized rod and another one missing a tooth from second gear. Surprisingly both were still running and riding up to when I tore them down. The seized rod would get stuck after running for a few seconds, you could free it up and it would still start right back up. They are great bikes as long as people keep oil in them.

Do you have a mechanics stethoscope? It has a metal probe you can move around the engine. Find where the noise is the loudest and you can isolate where in the motor the noise is coming from. Best 30.00 bucks you can spend for your tool box.

Be carefully with bikes with no Vin numbers. It's the same thing as stealing it. If you get pulled over with that in the bed of the truck your charged as if you stole it. Just avoid them all together even if they are cheap. I could of bought a new kfx450r back when they were new for $800 but I knew better. I've powdercoated many frames and my buddy has a business.

[@vwsandvettes3253]

After you saw the spark plug was loose, then verified the spark and fuel, did you put the plug back in tight and then try to kick it over once more? I wonder if maybe compression was leaking out the loose plug to the point where it wouldn't start.

[@madcannagrow2833]

I bought a xr600r for 500$ for this exact reason. Got home did a quick inspection found a loose spark plug tightened it down and starts first kick every time still to this day. That engine is a beast

I hate that. My Suzuki RM80 and then later down the road my Husky WXC 410 both had same issue. Fixed the RM, then broke it again and sold it. The parts guys at Husky were useless and never gave me a straight answer on part prices and said they'd call me and never called back (this went on for weeks), so I ended up just selling it as is to someone who wanted to turn it into a trike. Once again, the uselessness over at the dealership caused him to not get parts, and when he finally found a new crank, it was almost 2k, so he scrapped it.

had the same exact bike the rockers were so shot it was unbelievable that the bike even ran like they looked like they they were held on a sanding belt replaced the rockers and cam with new and i got rid of that ticking noise every single ttr125 makes also the only way oil gets into the head is from being slung up from the timing chain to so they arent oiled good up there from the factory causing that issue on every single one

[@ZachsUpOnOne]

im promising you right now that noise is the rockers/cam wear

[@checkforfleas9452]

Typically piston slap. Your not going to have much compression. U may get some. But. Nah. That was amazing. If he didn't run it with no oil. Could've not happened. Shit happens though. That bike is super clean and we'll maintained for it's age. Yea the crank is gonna be some monies. But u can probably find a good used one. I have faith in you putting on a new rod andcrank. But know they are aligned. It's a tough job

[@OGKILLa9365]

I had a old Honda that used to do this. It was the stator and cdi. They where just old and worn, they would heat up and lose spark, once it cooled down it sparked again. When it shuts off check for spark again. Just an idea

[@jamestaylor7746]

....Free FIX???? I had been thinking about contacting you to see if you could help with a '97 Suzuki DR350 bottom end replace/rebuild. The crankcase cracked (all the way across - both right/left and covers) while a friend was riding it. I was trailing him and didn't hear anything or see smoke.... he just pulled over and said something happened. Then I look down and see oil spilling on the trail, then see the internal gearing and bearings. It would probably make for excellent content, and I am extremely curious on what could cause such a catastrophe, without prior noticeable warning signs.

[@jamestaylor7746]

...actually, I commented before seeing this whole video and seeing this one ended up being a bottom and top end tear down. If working on the Suzuki is something you'd consider please let me know. Amazing how you get 'em running.

[@juk-hw5lv]

These Yamaha singles are horrible when needing to adjust the valves. The plastic caps on the left cover get stripped, and you need to disassemble half the bike to get the valve covers off cause the clearences are so minimal in the frame. I've hated valve jobs on my TW125 with passion. And riding without oil kills them in no time. I rode that thing with a slight leak in the oil line for maybe a kilometer and the whole valvetrain was shot

[@johnrettburg8224]

I'm thinking bottom could be a rod bearing since it was run low on oil.

[@physics1874]

What if the spring and gasket from the fuel screw are stuck inside and only the needle comes out, would that cause a problem?

Iv been watching your KZbin for some time and I’m amazed how good you are, could you help i have got a Chinese 110 atv and iv rolled it when rideing and now when I start it it just back fires when reving I think there’s oil in top end because the spark plugs black and keeps going black and oily what do you think mate Thanks

@@dannyjamison8337 It''s been sitting and non running since 78'. we lubed the cylinder walls a bit with oil before trying cranking it over so it was probably a mixture of oil we put in it and fuel but pretty much all of the gaskets/seals on it are either leaking or likely toast on it anyway.
