Timing is retarded real slow to climb. Defiantly put an air filter on might need back pressure

[@robertsumpter9970]

Not this video it's not reving out due to the fact rimming is off two screws turn magnito one way a little at a time till you get it you had it running

[@lawrence1986ify]

please look up "Heat shrink solder butt connectors" no more soldering all you use is a heat gun or touch and they are weather proof as well its perfect for what you need

[@jasonfife2751]

Reed Valve!

[@jonbaggarly6969]

I think it's firin after tdc

[@davebarrowcliffe1289]

Try this: 1. Check for spark. One kick is ample. 2. Order new gasket set, seals and bearings. 3. Remove engine from frame and get it on the bench. 4. Completely strip and inspect, clean and replace all seals, bearings and any broken or worn-out parts. Oil seals are simply not designed to last 3 decades! 5. Reassemble. 6. Put engine back in frame 7. Check timing with a dial gauge using timing degrees off the internet. 8. Clean carb and replace all jets making sure you have the right sizes. They cost pennies. Never run a 2 stroke without an air filter. Honest mate, it's a lot more satisfying and less time-consuming than endless fault-finding and troubleshooting. 😀👍

[@reggiexp69]

nah man that is to much :)

[@wallpaperman9051]

Try reeds as well

[@c.s.s.1723]

Sometimes you gotta burn down the village to save it. You are totally right about this.

[@bk6271]

makes for a boring video tho

[@johntunstall9698]

If you hold the soldering iron on the wire while applying the solder, it will flow into the splice a lot easier. 👍🏻

[@BadassedRC]

Ya! That way your just painting it on top of the wires. Let the copper wire melt the solder, not the gun. =) Great vid thank you!

[@robertsullivan8045]

...exactly!

[@staceysmith6518]

It’s a two-stroke Derek, being over filled on oil cannot affect how the boat runs the crank case is completely sealed off from the Engine cylinder

[@calebwinterbottom196]

I mean it could drag out the clutch right? Definitely something you don’t wanna do

[@catfish_lude]

and he put 10w40 in the gearbox

[@motoXcR]

obviously its the motor mounts xd

[@l.s.tukbigbud7715]

It's a motorbike Derek... not a boat Dave...

[@Muddymikey]

That's a '79. Check the reed valves for your bogging problem, they're probably not fluttering like they should after sitting for so long. Congrats on getting it started. (Oops, spoiler alert!!)

[@nou943]

i just had the same issue on a pw80 that im working on. I put some boyseen reeds in it and it runs much better now

[@wallpaperman9051]

I didn’t think about that. It could be the problem

Shut up millennial

[@mikga45]

Reeds after all those years should replace anyway.

I was really looking forward to this video man, thanks a bunch for uploading it.

He has had like almost everybody even the holy grail KTM 500 from like 1994 or something they’re all white

[@gerryh1746]

It doesn't sound like you have a spark issue. It's acting exactly like the choke is on.

[@raysmetaltracks6782]

Man, I dig your channel. Love getting into the details with you. Used to really enjoy working on my bike with my dad, brings back great memories.

[@briancrull8678]

I love seeing you go back to the roots of what me and a friend of mine were doing 25 years ago. Digging up barn bikes and riding the shit out of them if they’d run until they blew up

[@RcOffroad9513]

I just wrote a comment about me and a friend doing the same thing! Happy times back then! I think I'm gonna buy a fixer-uper!

[@staceysmith6518]

If it was a crank seal the bike would be smoking a lot more than what it is. Most likely it’s your carburetor settings or the timing is slightly off

[@carterwellman413]

It’s a two stroke.

[@robspear03]

@@carterwellman413 Which still has ignition timing...

[@johndallis9901]

Probably oil mixture, smoking means it’s working though so good.

Line up the lines and your in time . 1979 RM 400 rider ! Bought it new in 79 ! Still have it and a 1980 . Best motocrosser in the day .

[@Bigkuntri72]

Thanks for the videos. I love this kinda stuff and have learned allot from checking out your videos. I Bought an 86 Suzuki dr100 this spring that didn't run and got it running. Didn't take much. More TLC than anything. I'd like to restore it but parts are extremely hard to find at a reasonable price.

[@groovystuff1741]

cannot believe how lucky u are getting them bikes.happy for u.u do an amzing video all of the videos are really thorough as u explain properly

I can’t wait to get mine up and running!!

Such a satasfying video. Just found your channel and joining your community. I support all 2 wheeled content creators like us. Keep riding, keep happy! Excited to see what you post next.

[@waynesart8385]

This was my first bike here in new zealand, soo cool to see one coming back to life

[@RcOffroad9513]

When I was about 11 I bought a xr75 from a guy for $20 and some fake Oakley sun glasses. It didn't run, but I worked on it until I got it running. A few months later it caught fire from a backfire and homemade intake tube (a bicycle innertube) letting the fire out to where the carb leaked. I would fill the carb bowl and shut off the gas cause it leaked. One day I'm riding it with my friend and it ran out of gas. A construction worker filled the tank for me, and I headed off for the house about 3 or 4 mins away. I got to my yard and was hoping to get the gas shut off before anything bad happened bit it was too late, and being it had a whole tank of gas continuously leaking from the carb it was hard to put out. So I got rid of that and bought for $20 dollers! A 86 kx 80! It didn't have a cdi, so I put one from a older Suzuki model I can't remember what model but it was a 2stroke 80cc, and wouldn't you know it it fired up! I can't remember now why... but the throttle would get stuck open so We put a thick string around the sparkplug boot, too yank it off the plug when it would happen! It happened to me a few times! 😆 But boy did I love working on those things! I was 10-13 so didn't have any money but I could rig it up with superglue and duct tape! Great video man! I think it time to find me a used fixer upper dirt bike! Keep up the great work!

[@shotgunz1248]

Kids don’t do that kind of stuff anymore It’s all video games and junk My oldest is 25 now I had him riding bikes and Atv at 4 yo and helping me work on them Now my young one likes bikes and quads but he’s not into it like the older one It’s crazy how that happens and he’s been around them cause I ride and work on my own stuff He’s getting more enthused as he’s getting some older When I was a kids we was lucky to have a bike to ride I had a Suzuki jr50 and wore it out then a Honda trail 70 it looked funny but it was fun to ride lol

[@briangoscinak9725]

Save up and buy one! There are deals out there if you're quick enough I see running bikes for 700 bucks that are ugly all the time. Seat cover, spray paint and send it

[@jonbaggarly6969]

Cdi is everything without the right one it wont have the right firing order or sequence hope ya get it brother love the vintage bikes

[@nou943]

when you're soldering, you should heat the wires up and let the solder flow into the wires rather than putting a layer on. They'll hold much better if the solder works its way into the wire

[@richiefearn4214]

Before I watch ,I have full faith in you getting the RM going 👍👍

[@junkyardjimusa1195]

Love to see the new finds, you're doing awesome man. Props to you! No sponsor from good ol' dubya d40 yet eh? Lol

[@rigguyjt]

You should start using a dial gauge indicator for timing. If it is advanced at all, you can put a hole in the piston.

[@shaynedonnelly374]

Great advice but wasted comment he never listens and never learns

[@rigguyjt]

@@shaynedonnelly374 I thought I would mention it several times to express the importance of 2 stroke timing because you probably know how easy 4 strokes are to time. You can’t time a 2 stroke properly just by sight or else disaster looms.

[@jaredmcquiniff5362]

I wonder if the timing needs to be advanced a couple degrees. Great job on this project! From rust to riches!!

I bought a brand new 1976 rm 125. Top of the line back then. 6 speed gearbox. It was top of the line, then.

My first full size motocrosser. It was a great bike. In its time it was state of the art. The RM’s and YZ’s were head and shoulders the two best motocross lineups back then.

[@markhensley9378]

Really hope you can figure it out. You're probably right about the CDI and I wonder if changing the timing would help with the 250 stator and CDI?

[@dtaybrakin5450]

Can’t wait to see your first ride

[@handlebullshit]

Use flux when soldering and heat the wire, then add the solder. Let the solder flow into the joint, It's not paint. To prevent the heatshrink shrinking, put it on the longer piece of wire so it's further away from the heat. Gonna be a nice bike when you are done.

[@berghundkennel41]

thank you also for bringing me back in time

[@RobbyHughes238]

Hey great video here’s a little tip if it’s running kind of crappy that little tab on the bottom of the carb comes in contact with the motor and foams up the gas so grind it down a few milameters so it’s not touching it

[@nickgibboni8469]

could you explain more? haven't heard of this

[@RobbyHughes238]

@@nickgibboni8469 so that little tab touches the bottom end and all the vibration goes through the tab and makes the gas foam and get air bubbles so it gets more air then fuel and makes it idle higher

[@phillipwagner7347]

Took my jug to a shop yesterday and have to get it bored to the next size bigger!! Have it back in a week or so!

[@crazymotoaction]

You need to check those reeds out and check the carb sounds like not enough fuel or broken reeds

[@just_in_time5518]

Love this bike!

[@kurtyoung6769]

I've hesitated in the past to correct your starting procedure on two strokes. Do not twist the throttle with the enrichment knob pulled out. It's not a choke......it's an enrichment circuit that only functions properly with the throttle position at idle.

[@c.s.s.1723]

A lot of snowmobiles have enrichment levers with 2 positions. Thank you for pointing out this crucial detail. It is too easy to make that mistake. It is NOT a choke…!

[@nathanpalmer2086]

Another smasher top content bud. I think most definitely the cdi.

[@killaquarryservices3065]

This bike has done very little ,you found a really tidy bike 1979.I had 78 many years ago first thing I rode with power band!! Happy days 👍

[@edwerts7096]

Ok that makes sense if your using the wrong parts. I look forward to you riding it!

[@shaynedonnelly374]

He'll ride it but it will run like trash and he'll say it's minty lol.

[@haydee3260]

its your air fuel mix you need to restrict some air coming in an air filter might do the trick!!!! has happpened to me with 2 stroke bikes all the time

[@BitcoinYooper]

That's what I was thinking, messing with everything but putting an air cleaner on it. Just ramming unmetered or unrestricted air to it. Like ah fix that prolly rev out.

[@joshuarainey6796]

I miss my 82 rm, was a great bike

[@bananabrooks3836]

Rm 250 on the trailer looks like a '77 or early '78 model. Your Rm125 uses two intake systems piston port low end, then 'case reed' (you've not checked the reeds or reed lands yet) opens up for mid/top end. The cdi and correct stator part no.s can be identified from incisive googling presuming the part no. is still legible on your cdi. I think you can buy complete ignition and Boyesen (rad valve?) reed systems both cheaper then stock even if you can find them.

[@timfaulkner852]

Totally correct you need the right CDI unit for that yr of bike, they were a big prob bk then..

[@alanjaldred]

One little tip. I notice in a lot of your videos that you give it throttle as you kick the bike over. This often makes it harder to start the bike. It's normally easier to get it to fire and then if it fires, THEN give it gas if it needs it.

[@mrpenland]

do you think the reeds could be froze up or too stiff???

[@wallpaperman9051]

I read another comment about the reeds and I think that’s the problem, just not gettin enough fuel air mixture

[@dennisbagatin4480]

Nice fix but I can't stop drooling over that 350x in the background ✌

[@timneeley4040]

Spray startingfuild around head and cylinder while running see if it revs up. Gaskets could be blown. Could be e plug

[@nickgibboni8469]

i believe he did that. 29:35.

[@Dakindbrew]

My first bike wuz a '80 RM80! had her for like 16 years till she died onna logging road somewhere. Energy can't be destroyed

[@GarbageDanks]

I have to do the crank seal on my 01 CR125. If you let it sit for a while it starts out super rich and smokes like crazy and then evens out. It's gotten real bad where it has a constant rich condition no matter how much you lean it out. Replacing it this weekend.

[@TimArmbruster]

Cool! getting close.

[@lexomotorsports]

Any luck on finding some land ,the land I went to see sold the same day ,still looking

[@leekgt]

Got that hoagie runnin!! 🍋🔥

[@Coyotethumper5]

Yeah that CDI and stater definitely looks like the one I had on my 79 arm 250 and I had my stater go out on my RM 250 well half of it and I had to replace it it would idle but soon as you touch the throttle it would die and it also would run hot just at idle but once I replace the stater ran like a champ

[@daryleduardo7055]

Want to know how I know this? I had a early 2000s Yamaha v Star Silverado classic edition are in the engine without the air filter to see if it would run it didn't rev up it would stall and die it would idle fine as soon as you hit the throttle it died so I put the air filter element back on in the air filter cover and it was like a new machine reved up smoother than hell

[@ty717atv4]

Thanks for the great video stay safe brother

[@joncooke479]

Thats a rocket ship when running, if the carb is correct and it won't rev high it will be the high revs coil failing in the stator assembly. Had exactly the same problem back in the day on the exact same machine!

[@gordonwrichert8240]

when you first turned on the fuel on and tried to start it the gasoline was running out the bottom like Niagra falls the floats in the carb are not working properly

[@stopcensoringmyfreespeech3280]

like you said it starts and the carb is working. found the seat. are you going to put the CDI in the toaster.

[@rm25088]

that guy was smart. he made you buy both bikes for the parts for the 125.

[@oo0Spyder0oo]

Yeah the stain showing where the logo goes up the tank suggest it’s the 79 version. Have you checked the cc stamp between the fins? What does it show?

[@mechdesigner9304]

Start with the fundamentals. check compression, do a leak down test if you know how. Leak down will tell you if the main seals leak or you have a gasket leak. use a new plug and check the color of the spark. Light blue is optimal. check the reeds. check the timing. and use some good gas. You cleaned the carb and the pipe isnt the issue unless its crushed.Check the jetting specs too never assume the jetting is correct. Could be a way big main jet with high float level..

[@11GalleryATV]

Definitely a 1979 - the 1980 had a smaller rear fender, and the 1978 has a different gas tank

[@mikeleblanc2933]

Careful with timing.....to low it will bog out.....to high it will burn a hole right thru the top of the piston......happened to me twice on wiseco new builts......cost me 2 pistons before getting it timed right.

[@j-beatsimaginationstudio1987]

LOL WOW What a great deal! Got your parts too! Be safe Brother :)

[@MaNNeRz91]

Was that fuel pissing everywhere when it came off the stand? 😆😆 And sounds like it's bogging from too much fuel but could be the choke 👀

It's a live great job bro

[@samlindow3425]

Can't wait for diagnosis I was saying main jet if not standard. Or wrong stator

[@m8fusion712]

Awesome video

[@rigguyjt]

Do yourself a favor and order a dial gauge indicator while your at it. They’re like $50. They are a necessity. Once you’ve used one, you’ll see what I mean. There’s nothing like a properly timed bike.

[@louisjohnsonjr.4934]

Its sat for a very long time it may just need running for a while to get the seals hot enough to seal the engine up good.

[@richie8214]

New plug I would before anything

[@troyaldridge3853]

u can solder the end back on the throttle cable joe

[@tonydevlin3062]

Have you ever had a honda qr50? I live in the UK and am currently restoring one now.

[@crown_3526]

I had a blaster that kept throwing me through a loop couldn't figure it out doing the same thing. Ended up being the crank seal. Looked like the ppl that owned it before could not get the cab to stop leaking from the bowl so they PLUGED the drain on it lol 🤦 filled the motor full of fuel and blew out all the seals on it.

[@gearhead762]

Alot of older bikes have the year stamped into the head tube

[@tobyparris4236]

Probably completely wrong but because your not running it with an air filter wouldn’t the jetting be out which would be cause it to bog ?

[@jockjones3024]

It looked as there was no air filtter i think its getting to much air my street bike did something similar to the when i cleaned my carbs and tried running and riding it down tbe road...put air filtter and air box back and she ran fine

[@DJS1989]

Make sure your putting a washer under the main jet!! Also check the main jet size...

[@thetwostrokerebuilder]

Doesn't smoke enough for crank seal. And even if timing is off little it would run better than that unless something isn't right. Pull cylinder and check reeds might have broken one

[@jaygtgarage6489]

The rm125 I had in tht year the black lead tht comes out the stator was at the top

[@daymianmorin5074]

I have the exact same bike and i have the exact same issue, I adjusted the timing did not fix it, bought new reeds did not fix it. I think its something in the carburetor, i know on the older bikes the float needle can sometimes fail. So I bought a new one and its 3 days out now. Hope it helps

[@GoodlookinMug]

The ole’ crank seal bog eh lol

[@philly_jay_vlogs]

Did you check air/fuel screw on carb

[@daryleduardo7055]

If you do suspect the air filter 30 or $40 air filters a lot cheaper than an engine rebuild just swap the dang thing out with a new one

[@j-beatsimaginationstudio1987]

Def sounds like the issue Brother. You got this tho!

[@arrowcarter1522]

Hey I have the exact same bike but I’m missing a spark arrester and a thruster washer. Are you going to use that bike because I can’t find parts for mine anywhere would you be willing to sell me some?

[@DeveroyB]

This problem could be timing that is out or weak spark. I experienced this problem with a suzuki ts50

[@officialmilehigh5207]

could it be wrong jets in the carb?

[@theboogieman401]

Good pick up and I like that you got that little ultrasonic cleaner I’m gonna grab one for 70 bucks for the carburetors and small parts - it’s the same model that you have do you think it was worth the money?? Has it broke on you or anything like that because I seen that you did a really good job with that carburetor I have it in my cart but I just don’t know if I should buy that one let me know how it’s been working for you

[@wannawin95]

their all cheap chinese junk. All likely made in the same factory and with a different company's logo slapped on it. I've used mine a bunch of times, really comes in handy. Just need to be gentle with it, otherwise it will fall apart. Had mine off Amazon for 2 months, then the plastic on/off switch broke. Returned it, bought a new one.

[@richardkey4289]

[@olliekeogh2835]

Should have a look at swapping it for the other cdi box, if you got two with it it’s likely one had an issue
