- OHHH $#!! NO FRONT BRAKES!
Hellllo everybody! In this video, I take the rare $150 barn find 1983 Yamaha RX-50 on its first test ride! I also filled up the tires with air, changed the kickstarter to a better one, changed the oil, changed the air filter, added a chain, and tried to fix the front brake master cylinder! That's right, I TRIED to fix the front brakes, buut I guess it's time for a master cylinder rebuild kit! Thanks for watching!

Thanks for watching everyone! Thumbs up this comment if you want to see me keep working on this thing and make it run better! Top speed video soon? Happy good Friday and Easter to those that celebrate!!
You're welcome fammo
Yo when you were *oh shit there’s kids up there* I was in tears haha
The bugging is probably just shit in the carb - with it being that old and the inside of the tank probably not in good shape then small bits of shit can partially block the one of the jets - it then flows through and more shit does the same thing. Some comment below are talking about compression - but compression doesn't change from 1 moment to the next......
It must be having oil pump to did u check ??
If you put oil in the tank it's over oiling as its got an oil pump .....
Use motorbike specific oil.. that oil will make the clutch slip... Which it looked very much was happening in your video
I never had problems using normal 10w-30 with a wet clutch. I used it in many Suzuki PV 50cc mopeds and I had even changed the cylinder to 80cc to one of them, no clutch slip at all. I suspect that has just clutch plates gone, or close to gone.
My dad bought me one of these bikes when I turned 14 and I loved it. He paid also $150 for it and it had around 300 miles on it. Practically brand new. He bought it from his best friend who owned a used car lot. I rode that bike like it was a motocross bike, seriously, even sneeked onto a local motocross track many times and ran the mess out of it. Regarding hand starting. I could start mine up also with my hands, even when it was new, they just are little engines that are easily turned over. It was very reliable it never left me stranded anywhere. It's max speed on level ground was 54mph and for a 50cc stock that is faster than any 50cc scooter out there stock on the road today. I truly wish my dad would had put mine away in his shed for when I got older because I want it back extremely bad. Alot of memories for that bike and many fun stories of my childhood with it.
It will just take a little time to get all the bugs worked out. But SO worth it! Keep it up GoldGuy!
no front brakes.. bunch of kids .. and you decided to drop a gear and accelerate?
XD
It was either that or stall it in front of a ton of kids, and I just wanted to be a good role model
If in doubt, power out 😅
@@joshuadathsbc5765 i guess the 50cc really helps with the power. HAHA
@@Jasonnnnnnn007 haha
great video thanks.Cool bringing old machines back to life. You live in a lovely neighbourhood. Respect from England.
Cool build for an old bike. This would make a sweet cafe racer, with an old school vibe, conversion project! Keep doing what you do!
Yep... Fuel delivery issue... And yep, never use standard oil, but always use motorcycle oil designed for wet clutches...
use proper motorcycle oil that car oil is not good for the clutch
Yes car oil has friction modifiers no good for wet clutch ...
clutch plates are probably glued together anyways.
Ya know what I was going to refer to some bikes don't have wet clutches and then i remembered its two stroke lol. Holy shit. No he also took the damn baffle out too. Two strokes require that back pressure to run right. It will fall on its face like that with no back pressure. I know u said 10 w 30 lol but that meant motorcycle oil lol
Alright, you're right. That's just what I had laying around. I'll get some better oil. Any recommendations?
@@GoldGuyRides really any thing for wet clutches. I mean it depends on how much u care for it. I'm not sure that any of them are any better than the other. Personally I like castrol anything.
I got a 25 year old rx100. Damn,these things are beast. It does 100km/h tops
My dad had one back when I was just 8 or something.
i have Rx135 and can run upto 210km/h . i modified it to 6 gears.
I love your spirit young man ,you live in a nice neighborhood ...you are very blessed!!
13:29 NO BRAKES! Tons of kids in front. Then full throttles it when passing them LMAO
3:27
Boom 420, great videos brother keep them up. Greetings from nl
I would have oiled the filter but not the pre-filter. But that's just me. Nice to see that old stuff running!
i love little bikes !
Use an impact wrench to get those tough screws out. Use the proper motorcycle oil. I use Castrol Power1 20w-50 4t in my 1971 Yamaha ht1-b 90.
Like the vids! Keep on working on them old bikes. They're tons of fun. You'll stumble and learn along the way just like all of us.
That master cylinder was gnarly! oh my!! Nice video, Mason!
You reminded me to my uncle...he has suzuki rc 80cc and the bike sounded just like this..rip uncle johnson..1961-2014..
Where’d you get the ignition and keys? Did they work?I need one for mine
Try to rinse tank again, add a fuel filter, and clean carb again before trying to rejet. That will probably fix the boggyness. I would start there first. Also great to see you using a rubber mallet and torque wrench in the last few vids. Thumbs up. The gunk in the MC is probably in the brake lines too. Try to clear the line if you rebuild the MC. Bleeding brakes on bikes can be tricky I had to reverse bleed my front brakes on my 78KZ650sr and finally cleared the air out of lines. Great collection of bikes
Damnit, now I miss mine, riding fast on a slow bike is a hoot, and thats about all these are good for.
Bleed from the banjo bold on top of the mastercilender of the front brake that worked really good for me also had no pressure at first even after bleeding
Judging by the bogging and how easy it was to kick over... I think you have a compression issue. Might want to source some new rings.
These engines turn over ridiculously easy, that's normal. However I agree that there seams to be some weird compression issue. I've had 1 of these engines for 5 years and rebuilt them multiple times but I have never come across that compression issue
@@ANDROID204 I've had 50cc mopeds you couldnt turn over by hand... but you're right. Could be the nature of the beast. Hard to tell from the video but the top end sounds tight... no clanging or slapping like the jug is worn.
Actually I can tell that it''s very much the nature of the engine as I own a DT50MX that has the same exact engine. And it turns over almost if not just as easy as mine.@@AimlessMoto
Yeah i have a DT50MX as well, and they are very easy to turn over, so that's normal, but the bogging could be something stuck in the main jet as well right?
@@Erik_Blomgren It definitely could be, it could also have somthing to do with the ignition.
No brakes! Absolute Mad-Lad!
nice work! even though i like dirtbikes ,its very enjoyable too see ,cant wait for next part
We will see if it fits...
Smash smash smash
If not you'll make it fit 🤣🤣👍👍
Love this bike super fast I have one til now. ☺️
Absolutely enjoyed it!
You should find a Honda CT90 for your next bike! They're really great small CC bikes and they're loads of fun. Love your content anyway mate ❤
The brake fluid issue was cause by a previous owner mixing dot3 and dot4 liquids together causing it to gel up and ruin your brakes, hope this helps
Dude the reason I suscribe to your channel was when you were putting some air into the rear tire and the funny big flame explosion haha you said he’ll not leaks too
i cleaned a master cylinder that looked almost like that, except the crud was . . . crunchy.
i cleaned it, then put fluid in it. the thing had compression because it would not move very far.
i took it apart and found that the crud had made its way into the piston compressor chamber, and that same crud was everywhere.
later on i found out that the break line ( this one had 2 sets : solid line and the rubber hose type to the brake cylinder ) ,
had a build up of crud at the union section ( nut screws on to the metal male break line ) , so i used a clothes rack wire
( a thick one to with stand the pressure i was going to put on it ) and straightened it out , put the tip of it in the metal break line
and the tip of the rubber hose to clean it out. it had stopped it up.
then took apart the break cylinder and removed the old gunky molasses ( old break fluid ) and cleaned the cylinder out.
put everything back, filled it up , and now it works. BUT, now i have to take apart the break lines and use chenille stems
[ pipe cleaners as i call them ] ( chenille light brown 50 pc. #158469 0.24 x 12 inch (0.6 x 30.48 cm ) )
to clean out the remaining gunk and make it clean again. but before i put it back together, i will soak the rubber lines
in 303 aerospace protection ( because they do not make that type of break line anymore. ) to preserve the rubber for a longer
time frame.
submerge all of it for about 30 mins. take it out and let the 303 fluid drain into the jug, cleaned out milk jug [ gallon ] .
((((clean out the hoses before soaking )))) , and let hang over night for 12 to 14 hours, so the 303 can do its job.
you wont regret it.
also , clean that seat off good. then spray the 303 on it. respray it 30 mins later, and let sit over night for 12 to 14 hours.
do the same for the tires, why ruin good tires when you do not have to. . . . [[[ yeas it will work on that type of rubber too ]]] .
if you need the stems longer, just solder the tips together, just remove the fuzz first to make a better connection.
as for the exhaust smoking alot, looks like you have to much oil mixed with the gas, causing the engine to die out. also probably
from the amount of oil for the filter may have something to do with it .
wrong type of oil to use in that engine. remove it , and put in the correct type. may have to do a clutch replacement now
due to all the revving at such a really low movement.
awesome video !!
1000 thumbs up !!
Love these videos
I had one of those in 10th grade. I was 15 years old and drove it all over town. Video arcade was my favorite destination. Very strange bike I must say.
thats awesome! my first ever bike was a 2 stroke yamaha tzr 50 from 2006 so it brings back memories!
whats the purpose of the air filter oil?
Just extra protection from dirt and dust getting in
I would like to suggest you to check the muffler if it clogged and retune/rejetting the carburetor
Just discovered your channel, great videos! Following for sure 👍
Change the line and also check the caliper
What they said ... about the oil and fuel mix . but more crucially the thingy you took out the exhaust , maby put it back concidering two strokes get all of their power from compression and the exhaust properties . so messing with that will definitely strip power. cool lil bike to have fun on tho
very cool lookn bike!
Hey GoldGuy, Thanks for this video. I got one of these RX50s recently (much better shape than yours :D ). This is a real streamer, love it!. I am interested in the ignition switch installation (someone replaced it with a simple switch), pls make a detailed video once you got there. Thx!
nice bro !!!!! beautiful motorcycle i have too 50ccm bike its called simson s51 enduro
8:06 dont touch it it can damage ur hand brake oils never good for skin or anything
Good job. Sounds like clutch is slipping!
You don't happen to have any suggestions on where to find a replacement RX50 carb do you. The one on my bike is shot and Mikuni no longer makes the VM16.
you should up the mainjet now that you put on a open airfilter, the original jetting is for the closed airbox and therefor there will not be enough fuel for the increased amount of air that you now have, also you should probably rebuild the cylinder ;)
clean the tank again.and use a little less oil in the mix.use oil made for wet clutch.remove and clean out the exhaust and reinstall the baffle how it was.
Even though this is very un proffesional its still very entertaining. Good job
This will be the guy to upload a video in a year or two titled "how I lost my legs"
Bore hone new piston rings clutch plates gasket kit complete new brakes all around repack ur exhaust take the dents out ur tank with pressure new plug original Airbox with original air filter and new tires and a new paint job then ur good
So basically just buy a new bike lmao
Ouch that was kinda painful to watch. I think the clutch spontaneously combusted. lol. I missed the part where u added oil but yeah you should always use 2 cycle oil at around 25:1 ratio. I'm sure you're well aware of that. Brings back memories, my first "street bike" was a RX50 back around 1990 when I was 15. That thing was indestructible.
With that free-flow air filter, you are making it run lean. Which will destroy rings an cylinder pretty soon, cause 2-strokes get lubricated only through the lube in the fuel. Cut up some pieces of air filter foam to the shape of the original filter and put the air filter box back in there.
Don't over fill the oil ,get a new plug ,make sure the battery 100%, put in a new carb kit after you soak it in carb.cleaner,but a air cleaner,replace all the tubes and hoses on the carb .make sure the tank is very clean.
Do a compression test on that cylinder
Try it without the filter intake, and setting up the carburetor. If the compression feels weak, maybe you must change the piston ring
5:30 shouldn't you wait it to get dry before putting it on and ride?
Junk in the gas tank got sucked back into carb?
great little bike.
car oil has friction modifiers in it. you need to use v-twin oil designed for use with wet clutches. you will need to flush it twice. you will destroy the clutch using regular oil.
Does the carb not have a mixer screw you can adjust to let more fuel in?
Hey good video where do you find all of these amazing deals as im looking to start a restoration project but i can nver find any good deals
Yea, I put heavier springs in my clutch xP if I hit a bump it would slip. Lol my cable was properly adjusted as well. But using the wrong oil doesn't help xD
I know others have said car is isn't good and yes correct. I would definitely try and find a Yamaha oil just for the transmission side of the engine. Since it's a 2 stroke I'm sure the oil has to be mixed usually before you put the gas into the tank. It being Dutch a old bike I'd keep the mix around 25:1 and run a good Yamaha 2 cycle oil
She also sounds a bit rich
Or lean. Can't really tell..
Did you move the chain adjustment all the way in before you fitted the new one?
Also good practice to replace the sprockets at the same time, provided they are worn. Will help you get more life out of the new chain. Keep up the good work
Was waiting for this vid
Brake fluid is Hydro scopic meaning it attracts water when the mix brake fluid changes from a liquid into a solid clogging up the hydraulic system . Have rebuild a couple brake systems .
Sorry dude but what? Brake fluid is HYGRO-scopic with means it absorbs moisture from the air. If the system is air tight then nothing happens....
Where does the air escape? Because my rx50 master cylinder has a definite leak in the rubber boot
If the boot is leaking you might need a rebuild kit, but to bleed the line air can come out of the top where you fill it up or down on the bleeder screw on the caliper
I bet the neighbours love you :D
Did you mix oil in the gas tank ? That bike has an oil pump that means your over oiling ....The front brake may needs seals in master cylinder
That brake fluid has fermented by time and became cheese :))
probably ignition gone, put new condensator and points to be sure and cancelling out. cheap fix, i do this standard on old bikes wich has not run for a long time
Kids all ran away 🧸🎈
oh man free seed spreader at 15:00
did u put oil in the gas? (i guess so cause the smoke from the exaust)
Your hood looks clean where is it?
Try adjust the float valves or get new piston ring that might fix ur bogging issue
Careful running with non standard air filter on a two stroke , fast way to a melting piston if not jetted correctly . But your doing great
Om Alive at last i experienced that last week, i got a litle hole in my piston now
It's a two stroke you need to mix gas. I'm guessing. Also wet clutch oil.
It has an oil pump that means you don't mix in the gas tank or it over oils and bogs down oiling the plug
@@omaliveatlast4688 are you sure that old moped has one?
@@miksu7784 also he pulled the pipe off that feeds oil into the engine near carb
prob mixture, good call bro
It’s probably running lean considering you put a pod filter vs the stock air box
about the brake u bleed the air?
Remove the air filter completely, that may remove the bike's will to die when throttling at low speeds. If that's the case then get a better airfilter.
It's smoking a lot because it's running on petrol oil plus the autolube pump oil at the same time.
About the compression.. That is the same motor as my DT50MX has and everyone with that motor has bad compression. So i guess Thats just how it is. But it depends on HOW bad the comp is ahaha
Oh shit there are no brakes
*THERE ARE A BUNCH OF KIDS UP THERE*
Just find a newer working master cylinder. The brakes in the early 80s were just a suggestion when they were new anyway. Look at how small the disc is compared to the wheel diameter.
Wish you lived in antigua so i could buy it from you
Edit:im into bikes and cars buuut i dont have money to buy one tbh
You should make cleaning and poloshing video, Thumbs up Great job
Possibly your clutch cable is sticking, which can make the clutch slip.
10w-30 in a transmission?
Is it 2 stroke or 4 stroke? It sounds like 2 stroke???
It's bogging because the air fuel is off you have to tune it for that type of filter I put a uni on mine and it was running bad also because it's air fuel ratio was off because the filter is allowing more air in it than the stock
Cool
hello i'm about to buy an E-ton Matrix scooter thats been sitting for 10 years outside. What do I need to get it to working condition? it only has 63 miles on it. I'm a noob at this stuff but I want to get into it it looks fun!
Well if it's been sitting outside for 10 years then it probably needs a lot of work! But with enough dedication, there is nothing you can't do. Start by cleaning out the gas tank, putting fresh gas in, check the air filter and if it's somewhat clean, try to start it!
@@GoldGuyRides thank you!! i will let you know what happens thursday!
@@GoldGuyRides how do i go about cleaning the gas tank?
@@GoldGuyRides hey i tried kicking the kickstart lever but its really rusty. when I kick it down it's hard to pull it back up. I have to jimmy it back and forth. Do I need a new kickstart lever? or do i need to completely open the kickstart and lubricate it? when I push the kickstart you can see the lights come on temporarily.
You need to upjet as it’s sucking in to much air
Subscribed!
the brake fluid in my yamaha rt180 was the same
You’d be badass to hang out with 😂
You should do a engine rebuild
Lol trust me there’s is still a piston Made for it . Send the jug off clean the Caen rejet
What does the air filter oil do?
keeps the dust particles out of the engine
