Am I the only one who can smell the 2 stroke smoke whenever he fires one of these vintage bikes up?? Brings me right back the the 70s and 80s tearing up the streets and trails of NJ.
BRO, i had that very bike in 75 when i was 6 years old. i had to stand on a crate to get on and ride, or run alone side and jump on, also had to mod the clutch by lengthening it because i wasn't strong enough to pull at 6. thank u for the time. the memory and the video
My older brother had a TS185 that I would sneak out from time to time if my bike was down...I had to do the same type things to ride it, coming to a stop was always a planned thing up against something or like you, jumping on or off while moving. Those were the days! I found out when we got older that he knew when I rode it but didn't care. lolol
I always let things slide. You are a good mechanic. It killed me when you tried to take off that gas cap! Slip joint pliers (channel locks) are directional pliers! I kept on saying no, no, no! It will jack up any surface if used the wrong way! Keep up the good work!
Should have used a rubber strap wrench instead of channel locks. No damage and it would have gripped and worked much better. NEVER go at things like that metal gas cap (all original) with aggressive tools.
I had a '74 TY80 as a kid.. white with yellow trim, pretty much same engine and oiler situation. My buddy had an XR 75 and I dug the look of the high front fender so I "modded' mine and thought it looked a lot cooler. Did a lot of wrenching on that bike and learned a ton. Seeing and hearing this bike brought back all those memories and how much fun we had rippin' around the apple orchards in the Northern California wine country!! I dig this guy's channel and how he likes and respects these old gems
I bought my son a TY80 for his seventh birthday, two actually because I never knew if he wanted to ride. I let him ride one as a field bike to see if liked it but made the first immaculate. That thing is now nearly the price of his first road bike ten years later. I’m 6’4” and still ride the field bike for a chuckle. It was my first trials bike at 7 years old so I’m trying to stay young. Ours in the U.K. were white although we got a lot of US imports in junior trials that were yellow.
That's really cool that you still have those. I realize now what a piece of art they are in their natural state. Wish I still had mine! Cheers mate!@@DanDan-jc3it
Had the same bike! Could climb any hill but couldn’t keep up with friends on if we were on the roads. My friend had the GT80 (why I looked forward to the video) and others had YZs. Miss those days!
I had 7 GT80 / DT80's, it seems that almost all of them ended up having bad crank seals from age causing them to either have an air leak and rev to the moon or suck all the trans fluid into the combustion. But these things are actually pretty quick when they are dialed in!
I politely but heartily disagree. We did live in upstate NY, so this could have been a factor. The only people with blown engines were those who left this system in operation. I let the dealership talk me into keeping it hooked up on my 433 and it failed. Not the GT80, not the DT125, Not the 175 and not the 400. 32:1 and you never had an issue.
Kinda off topic and a random thought, but would bypassing that pump like he did cause the pump to burn up? No oil flow, then seems it would build some pressure blocked off like that.. I've only delt with 2 stroke oil injection on old polaris quads, never seen one fail on those.
I had the same bike...My 1st bike and learned how to rebuild a engine, at the age of 14. And the motorcycle fever kicked in. I had built many bikes ....Nice FIND !!!
I love your video's,,,, but will never understand not pressure washing them before you start to lesson the contamination of the work you do to them. A little NAPA Aluminum Brightener does wonders on Old stuff too.
kinda makes sense now why the fuel screw was turned all the way it with that super rich condition. Rule of thumb on carbs is if screw is on air box side (air screw) if the screw is on motor side (fuel screw). Fun videos like re living my youth. Smiles
Helpful hint.......when using Channel Lock type pliers, turn them the other way from how you had them. The pressure from your hand will assist in clamping the pliers harder on the object you are looking to loosen. The way you did it is actually causing them to slip.
Love your videos but would really enjoy them more if you cleaned up these bikes before you started working on them. I have worked on motorcycles as a hobbly for 50 years and have always found it more enjoyable and easier to work on a clean bike. Also, as a viewer, it's always great to see what a barn find bike looks like under all that dirt!
Joe, I’m sure you already know this but I feel the need to point this out. When you were using the channel locks to get the gas cap off and struggling to do it, if you flip the pliers over that will cause them to bite down more on the cap making it easier to remove it. I’ve seen you do this several times in videos now. Hope that helps.
Whatever you do, do not clean anything before you dismantle it, do not clean any used parts etc before you reassemble it, always re-use old toasted gaskets, alway use too much rtv on you toasted gaskets, make sure you dig around and scratch up inside the carb and petcock with a screwdriver and always always use your tools incorrectly. 👍
I had a 73 80 GT Enduro, maroon with gray. I loved riding that bike and outrunning my brother on his 3 wheeler. It would go around 40 mph if I remember correctly. Thanks for bringing some of the best childhood memories back to life!
I ran my 1970s Yamaha Enduros without the battery. Battery are for the lights. If you don't use gages or lights the battery isn't needed. One screw holds the Silencer pipe in. Take it out and clean it.
Agreed! We ALWAYS disconnected the Autolube. 32:1 and you never had an issue. Dealership talked me into leaving it hooked up on my 433 snomobile and I didn't even get two months before it blew. Yes, we made certain there was oil in the tank.
The seventies and eighties Yamaha enduros all the way up 9o 100 125 without electric start. 175 250 Enduro 360 Enduro none of them needed a battery to run that's called a battery and coil ignition and this little bike doesn't have it The early 125 had a electric start Dynamo that was 12volt
This was my first motorcycle. It was a present for my 8th birthday. I finally let it go 20 yrs later,and regretted it. These bikes would run, no matter the lack of maintenance.
I bring Lawnmowers back to life in the same manner. Spark first, then the rest. I use carb spray down its intake to get it to spark. If it starts and dies, it's a doable fix. All in all, this is how I work on old equipment. No ether, just carb spray. I need to ditch the mowers and go back to bikes. To me, this is fun. Nice work.
Sometimes when the injection bikes have been sitting for a long time, oil will leak into the crank case, and it takes a while for it to clear out. Finally one Vinny can outrun.
I'm standing behind you Joe! I wouldn't pressure wash before bringing an old bike, back to life. Water can and will cause all kinds of problems with the electrical system.
I like your videos, but DUDE, you repeat yourself so often it's frustrating. We get it, the points are opening and closing, we don't need to hear it 5 times!
Had a 1974 GT80 back in the early 80’s. White will a little yellow. Great first bike. Clutch cable used to break all the time, otherwise always ran like a beast.
That brought back memories, I had the MX 80 loved that bike but it hated me, the number of times I had to push it home from our local bush tracks, at least it helped me learn how to work on bikes. Cheers from down under.
I really appreciate the jump cuts to the finished carb and being installed. I fast forward thru so much of your videos because it’s tedious and I don’t need to see it over and over.
I had the MX 80 which is identical to the Enduro and they made a GT also and they were all exactly alike but different colors. This bike made me hate Yamaha for a long time cause I pushed it more than I rode it. That auto oiling system is junk cause every bike I’ve seen like these gave trouble. I actually had a friend that had the Enduro and another had the GT and I had the MX. I’m 48 and still have Philip head screw burn spots on the inside of my right leg from wearing shorts and riding. I mainly watched the video just see if he got it running. I have a banshee now and have had it for 4 years and that is the first Yamaha I’ve had since having one of these bikes. I got a 1986 XR 80 after the MX and you can’t kill the XR 80 at the age of 12 and I never had to push it unless I ran it out of gas
I don’t remember how long I had the bike(my memory is a little fuzzy I was probably about 10yrs old) but I don’t remember having any problems with it 🤷♂️. That’s funny you should say , but I just bought a 1987 xr 80 project bike. Always wanted one because they were popular like you said. Almost have it finished. Love restoring these old bikes.
Thanks for the great videos i watch them all. 4:22 when using pliers like this you need to turn them aroun. The force of you pulling is added to the jaw grip. You are using the tighten direction You are adding engine oil upside down. Put the oil can spout at the top not the bottom
Dang, what a find! My 1st bike was a 78 YZ80 when I was 7yrs old...then I had a 82 YZ80J, 1st yr of liquid cooled, had the radiator on front of bike behind number plate...that thing ripped!
ACTUALLY, he said, something like, while shaking it..."ok it's not falling apart or things falling off" I don't think he thought it had a pin hole/full of fuel because he usually mentions that. Just my $.02
I went and looked at a old GT340 Yamaha snowmobile many years back. The guy wanted pretty much nothing for it because he could not keep it running. He told me it would run with the exhaust unhooked but not when it was. On a hunch I bought it, brought it home, took the pipe all the way off. Banged it a bit on the ground and shook out a coffee can full of cat food the mice had filled it with. 😳 The sled ran great after that for many years! 😊
When I was 12 years old, I had the RM 80 I think that would’ve been 1974 I wrote it for two years and then I got a RM 125s live in Las Vegas, Tropicana and Pecos. It was all desert back then now it’s a Walmart in Sam’s Club.
The sound, the smell and the tools: All great. Go on and watch the seals. Did you notice that the wheels are not in line? Seems like the frame or axels are bent.
Looking forward to the next video. This bike is almost good for a restore. It’s pretty much already done just needs the seat which you have and polish the fenders. Get a new headlight assembly which hopefully it comes with the brackets that attach it to the front fork and a rear taillight assembly.
1st bike I had early 70s a Gemini 50 then got a Mini Enduro 60 and man it was on! 70s,80s, and 90s bikes rule. Good find!,thats gonna be a sweet lil bike when you get done.
Great job, but a small tip. @ 4:15, if you place the self-adjusting wrench the other way up it tightens as you apply torque, so you aren't just relying on the force of your hands to grip the fuel cap.
It must be the same engine they put in the TY 80 trial bike. All gears are upwards. This takes me back to 1978. My young brother had the TY 80. Love your purchase. Well worth it. In 1978 my brother was 9 years old. ❤Ruth.
My neighbor in NC would restore old 50 and 75cc bikes. And when it would snow we would all go ride around down down on these little bikes. It was one of my best memories.
This was my first dirt bike , mine was red. . I traded a brand new pair of Pony leather high tops that I won from saving my Weaties box tops . Rode it for three years until I outgrew it . Wonderful bike ❤
I had the 100 Enduro version of this. Loved to see that yellow and stripe on the tank. Did like no maintenance on that thing and i crashed so many times at 14 that i traded it to my brother for a Honda XL75 4-stroke. 2 stroke Powerband and I didn't get along 😅 great videos and nostalgia my friend. Brings back cool spring days ripping down the country trails. That's what started my love for Motorsports.
Save your knuckles joe. Turn your channel lock wrenches the right way when trying to loosen something. When they slip and you putting torque on it, it hurts like crazy
I had a GT80 when I was a kid (now 59), not sure of the year though. Father bought it as a “basket case”. The engine was literally apart in boxes. He was in night school for motorcycle repair and made this a project to work on at class. It took forever to get done. They’d work on it maybe an hour or two a week, and it was always having to order another part, like they couldn’t look ahead and see what it might need.
Wow... great story. I'm the same age. My kids don't believe me when I tell them NO hardware stores had metric hardware. You either got it from the dealership or you had to wait for it to come from Japan. We never threw anything away and kept every tool kit from every bike.
I learned to ride on one of these back in 1979. Slow bike but a lot of fun. Bought a Kawasaki KDX 80 around 1982. Then grew up to a 1981 Suzuki Rm 125. Love the old school bikes they ran great.
that's false those Yamaha oil pumps rarely if ever fail. not sure why some people think that they were crazy over engineered..cudos for helping keep these old bikes alive 🤘
I have this same bike! This is the video I have been needing, awesome!! Also, watch all of your videos anyway. Thanks again for having the best channel EVER!
Dude ! Please learn the proper way to use channel lock pliers! Holy crap how can you not know by now ! Jeeze And if you think the pipe was still clogged why would you not take time to just pull it and confirm instead start it Rev the crap out of it to an extreme?
A 2 stroke Yamaha I once fixed with this exact same problem. The plug that seals where the ports were drilled though the casing for the oil pump popped out and the engine was sucking the gear oil from the transmission. I re-plugged the hole, being careful not to block the port closed, and the bike was transformed back from being a mosquito fogger.
I had a 74 with the head light and tail light. It was dark red. I redid the seat fork seals and new tires cleaned it all up and would ride that thing all over the place and I was in my 40s. Loved it!
My third. Had a Bultaco that ran for one minute. Had a Honda 50 mini trail that ran with kerosene in it. Had the GT80 that took the same licking and kept on ticking. Best times in the USA!!!
A 1976 version of this same motorcycle was the first motorcycle I ever rode. I went on to race a 1979 RM80N at Baja Acres in Birchrun Michigan. Man does this bring me back.
Oh what memories!!! my first bike right there. i remember dad saying you can't start it you can't drive it. did i ever try to crank that bike day after day. i was so happy when i finely got it. drove it everywhere. the only thing that was missing was the front fender. at 6 years old in 1980. this video makes me miss it.
Lil tip so you don't mess up your gas caps with those giant pliers.. Get a rubber strap style oil filter wrench. Cinch it around your cap and they normally come off fairly easy 🤙 Years ago i had a Yamaha 175 CT3 Enduro.. That thing reminds me of a tiny version haha.. Keep up the good work!
Its always rewarding to take someone's project, and make it run and ride again! Thanks for the journey. When I start a project bike for the first time, I like the preheat the cylinder. I use a propane torch to chase the moisture out of the metal, but a heat gun would work as well. I'm a Honda guy but I have a small box of parts for Yamaha 80s. Tach/ speedo switches headlight? Been years since I touched it..I will try to find it...
If the pump is working you don't need pre-mix, but it is a pracaution to have some pre-mixed oil till you make sure it is working. It is throttle actuated/regulated, so at idle it doesn't pump much but you can adjust it +/-
I still have my 73 DT250. New, it was $835 tax, reg and all. We used to wrap the tanks in a thin, flexible sheet of styrofoam that was used to package/box electronic equipment/stereos and then duct tape it around the tank. It kept our paint in good condition.
Those oil pumps are valuable and easy to work on. Usually, they only need shimming if the correct output can't be had. I keep them and repair if needed to use later. Plug/plates can be purchased on line (just 'bout like everything else) to close the opening in the engine when the pump's been deleted. The plug/plates are less than $20.00. I use the intrusive ones with rings instead of the flat plates. It's good to have a collection of functioning pre-mix pumps ready to go.
I remember Racing a guy on one of these things at the beach. I had just upgraded from my Honda 50 to the Honda XR 75 and I thought it was awesome. That Yamaha ran away from me and I was twice as good a rider as the guy on the Yamaha. Long story short that was my introduction to two-stroke motorcycles. Needless to say it was a long time before I ever bought another 4 Stroke.
Fun video Just a suggestion, When you were using the channel lock pliers to remove the gas cap, you had them upside down, or backwards. If you had turned them over you would see the proper tension on the plier. Try it, it's easier to see than explain
I grew up on a 73 MX80 white tank Yellow and black design like on this tank. thing was so reliable and fun. I then graduated as I got a bit older to my Dads 76 Honda Elsinore MR250 which I still have

Double sided finger nail file works great for cleaning the points. Sometimes you have to trim the pointy tip back.

The Yamalube oiling system was only a source of engine failure when you forgot to put oil in the tank!

On any Plier or Crescent Wrench, apply pressure to the fixed side of the jaw when possible.

I had that exact bike when I was a kid in the 70’s. Good memories
I had the MX 80 which is identical to the Enduro and they made a GT also and they were all exactly alike but different colors. This bike made me hate Yamaha for a long time cause I pushed it more than I rode it. That auto oiling system is junk cause every bike I’ve seen like these gave trouble. I actually had a friend that had the Enduro and another had the GT and I had the MX. I’m 48 and still have Philip head screw burn spots on the inside of my right leg from wearing shorts and riding. I mainly watched the video just see if he got it running. I have a banshee now and have had it for 4 years and that is the first Yamaha I’ve had since having one of these bikes. I got a 1986 XR 80 after the MX and you can’t kill the XR 80 at the age of 12 and I never had to push it unless I ran it out of gas
I don’t remember how long I had the bike(my memory is a little fuzzy I was probably about 10yrs old) but I don’t remember having any problems with it 🤷♂️. That’s funny you should say , but I just bought a 1987 xr 80 project bike. Always wanted one because they were popular like you said. Almost have it finished. Love restoring these old bikes.
Timing check . The Yamaha is notorious for that points gap out of spec.
Thanks for the great videos i watch them all.
4:22 when using pliers like this you need to turn them aroun. The force of you pulling is added to the jaw grip. You are using the tighten direction
You are adding engine oil upside down. Put the oil can spout at the top not the bottom
Dang, what a find! My 1st bike was a 78 YZ80 when I was 7yrs old...then I had a 82 YZ80J, 1st yr of liquid cooled, had the radiator on front of bike behind number plate...that thing ripped!
My 1974 Toro snowblower fired right up first pull after I did the points that I learned from u.
Before I even watch the video, I had an 74 and it was a little beast. Mine was same color and bought it for 100 bucks running. I miss it so much
I paid 60 bucks for mine. You couldn't kill it. I also bought a 1972 Plymouth Roadrunner with 42k miles for $650. Best times EVER!
I had one of these when I was a kid on our farm. Rode it every chance I could. So fun.
That type of carb float is a nitrophyl type, it is a solid block of plastic, shaking it will tell you nothing!
ACTUALLY, he said, something like, while shaking it..."ok it's not falling apart or things falling off" I don't think he thought it had a pin hole/full of fuel because he usually mentions that.
Just my $.02
I went and looked at a old GT340 Yamaha snowmobile many years back. The guy wanted pretty much nothing for it because he could not keep it running. He told me it would run with the exhaust unhooked but not when it was. On a hunch I bought it, brought it home, took the pipe all the way off. Banged it a bit on the ground and shook out a coffee can full of cat food the mice had filled it with. 😳 The sled ran great after that for many years! 😊
Watching you grab that cap with the multi grips made me cry :)
When I was 12 years old, I had the RM 80 I think that would’ve been 1974 I wrote it for two years and then I got a RM 125s live in Las Vegas, Tropicana and Pecos. It was all desert back then now it’s a Walmart in Sam’s Club.
@mrdavehb47. The RM80 was not released until 1978.
@@dannyjamison83371977 with the B model!
The sound, the smell and the tools: All great. Go on and watch the seals.
Did you notice that the wheels are not in line? Seems like the frame or axels are bent.
Looking forward to the next video. This bike is almost good for a restore. It’s pretty much already done just needs the seat which you have and polish the fenders. Get a new headlight assembly which hopefully it comes with the brackets that attach it to the front fork and a rear taillight assembly.
1st bike I had early 70s a Gemini 50 then got a Mini Enduro 60 and man it was on! 70s,80s, and 90s bikes rule. Good find!,thats gonna be a sweet lil bike when you get done.
Great job, but a small tip. @ 4:15, if you place the self-adjusting wrench the other way up it tightens as you apply torque, so you aren't just relying on the force of your hands to grip the fuel cap.
I had one of this 1984-86 but we change the engien to a 125cc wilde ride and werry mutch fun fore a 15 year boy here in Norway.
It must be the same engine they put in the TY 80 trial bike. All gears are upwards. This takes me back to 1978. My young brother had the TY 80. Love your purchase. Well worth it. In 1978 my brother was 9 years old. ❤Ruth.
My neighbor in NC would restore old 50 and 75cc bikes. And when it would snow we would all go ride around down down on these little bikes. It was one of my best memories.
Brings back memories! I had a 1977 my dad and i fixed up together when i was kid
That’s what happens when you run a 2 stroke bike without premix. Crank seals blowout really easy.
This was my first dirt bike , mine was red. . I traded a brand new pair of Pony leather high tops that I won from saving my Weaties box tops . Rode it for three years until I outgrew it . Wonderful bike ❤
It was 1978 and my mother bought me one of these for my 8th birthday. So much fun.
I had the 100 Enduro version of this. Loved to see that yellow and stripe on the tank. Did like no maintenance on that thing and i crashed so many times at 14 that i traded it to my brother for a Honda XL75 4-stroke. 2 stroke Powerband and I didn't get along 😅 great videos and nostalgia my friend. Brings back cool spring days ripping down the country trails. That's what started my love for Motorsports.
I had a JT 60 Mini Enduro, loved that bike. It was a sad day when I sold it.I bought it used in 1975 for $125.
I spent a lot of time on a Yamaha MX80 in the early 80's.
Greatest times in the USA EVER!
Man I did to I wish I would of keep mine was 1980 Mx 80 never did leave me walking things are just not built like that it’s a crime how the world went
Save your knuckles joe. Turn your channel lock wrenches the right way when trying to loosen something. When they slip and you putting torque on it, it hurts like crazy
Invest in an ultrasonic cleaner ! The ultimate shop tool that once you’ve used one you’ll never understand why you hadn’t got one sooner !!
He has one and rarely uses it. Drives me crazy. Every carb I work on goes through the ultrasonic.
Remove the flywheel, loosen up the stator and push the crank seal back in place. It'll run clean until you get a new seal. Easy fix.
No stator
I had a GT80 when I was a kid (now 59), not sure of the year though. Father bought it as a “basket case”. The engine was literally apart in boxes. He was in night school for motorcycle repair and made this a project to work on at class. It took forever to get done. They’d work on it maybe an hour or two a week, and it was always having to order another part, like they couldn’t look ahead and see what it might need.
Wow... great story. I'm the same age. My kids don't believe me when I tell them NO hardware stores had metric hardware. You either got it from the dealership or you had to wait for it to come from Japan. We never threw anything away and kept every tool kit from every bike.
I learned to ride on one of these back in 1979. Slow bike but a lot of fun. Bought a Kawasaki KDX 80 around 1982. Then grew up to a 1981 Suzuki Rm 125. Love the old school bikes they ran great.
that's false those Yamaha oil pumps rarely if ever fail. not sure why some people think that they were crazy over engineered..cudos for helping keep these old bikes alive 🤘
Regarding the Yamaha Autolube in the 70s, I politely but heartily disagre.
@peaceprayer595 you can disagree but you'd be wrong
@nostrem82 Did it ever occur to you that in all your moto genius, there could be other factors that play into science in spite of your experience?
You need to oil the filter with air filter oil in order for the it to stop dirt from entering the carb and engine...😢
I have this same bike!
This is the video I have been needing, awesome!!
Also, watch all of your videos anyway.
Thanks again for having the best channel EVER!
Dude ! Please learn the proper way to use channel lock pliers! Holy crap how can you not know by now ! Jeeze
And if you think the pipe was still clogged why would you not take time to just pull it and confirm instead start it Rev the crap out of it to an extreme?
A 2 stroke Yamaha I once fixed with this exact same problem. The plug that seals where the ports were drilled though the casing for the oil pump popped out and the engine was sucking the gear oil from the transmission. I re-plugged the hole, being careful not to block the port closed, and the bike was transformed back from being a mosquito fogger.
I had a 74 with the head light and tail light. It was dark red. I redid the seat fork seals and new tires cleaned it all up and would ride that thing all over the place and I was in my 40s.
Loved it!
I had a 73 Yamaha GT 80! My first motorcycle, and I loved it!
My third. Had a Bultaco that ran for one minute. Had a Honda 50 mini trail that ran with kerosene in it. Had the GT80 that took the same licking and kept on ticking. Best times in the USA!!!
A 1976 version of this same motorcycle was the first motorcycle I ever rode. I went on to race a 1979 RM80N at Baja Acres in Birchrun Michigan. Man does this bring me back.
Holy crap, I had this same exact bike when I was a kid in the mid 70's, so cool to see this again. Rode it hard, was a 3 speed
4 speed. All up
@@peaceprayer595 ahh, maybe, can't remember really, actually maybe it was my 1st bike that I had was a 3 speed, that was a honda,
my honda 50 mini trail was a three speed. what model was yours?
@@suespony
I would love to see you do a complete bottom and top restore of a vintage xr75.
It won't happen
@@wisecampmotorcycles8258 not his forte
Oh what memories!!! my first bike right there. i remember dad saying you can't start it you can't drive it. did i ever try to crank that bike day after day. i was so happy when i finely got it. drove it everywhere. the only thing that was missing was the front fender. at 6 years old in 1980. this video makes me miss it.
Lil tip so you don't mess up your gas caps with those giant pliers.. Get a rubber strap style oil filter wrench. Cinch it around your cap and they normally come off fairly easy 🤙 Years ago i had a Yamaha 175 CT3 Enduro.. That thing reminds me of a tiny version haha.. Keep up the good work!
Its always rewarding to take someone's project, and make it run and ride again! Thanks for the journey.
When I start a project bike for the first time, I like the preheat the cylinder. I use a propane torch to chase the moisture out of the metal, but a heat gun would work as well.
I'm a Honda guy but I have a small box of parts for Yamaha 80s. Tach/ speedo switches headlight? Been years since I touched it..I will try to find it...
Wow, that's what I learned to ride on. Thanks for posting!
If the pump is working you don't need pre-mix, but it is a pracaution to have some pre-mixed oil till you make sure it is working. It is throttle actuated/regulated, so at idle it doesn't pump much but you can adjust it +/-
I still have my 73 DT250. New, it was $835 tax, reg and all. We used to wrap the tanks in a thin, flexible sheet of styrofoam that was used to package/box electronic equipment/stereos and then duct tape it around the tank. It kept our paint in good condition.
Joe get yourself some Red armor 2 stroke motor oil . It's also known as 2 cycle motor oil to. It cleans out exhaust and carbon buildup.
At 4:14 Channel lock pliers are directional, and you were using them backwards.
The Channel lock 460 pliers would be ideal for this job.
We had that bike growing up. Seeing and hearing that bike brings back memories. Cool bike
27:49 You no the thing I love and have a chuckle at, most Americans always use an adjustable wrench, no spanners, but sorry he has got spanners, 😂
You can use one of the wife's old emery boards to clean those points! You can cut them to size as well!
Those oil pumps are valuable and easy to work on. Usually, they only need shimming if the correct output can't be had. I keep them and repair if needed to use later. Plug/plates can be purchased on line (just 'bout like everything else) to close the opening in the engine when the pump's been deleted. The plug/plates are less than $20.00. I use the intrusive ones with rings instead of the flat plates. It's good to have a collection of functioning pre-mix pumps ready to go.
I remember Racing a guy on one of these things at the beach. I had just upgraded from my Honda 50 to the Honda XR 75 and I thought it was awesome. That Yamaha ran away from me and I was twice as good a rider as the guy on the Yamaha. Long story short that was my introduction to two-stroke motorcycles. Needless to say it was a long time before I ever bought another 4 Stroke.
I actually have a titled dt80 from 83. Sold it once and bought it back bc i missed it so much lol. Great bike
Can’t wait to see next video on this lil beast God Bless hope your feeling better
Fun video Just a suggestion, When you were using the channel lock pliers to remove the gas cap, you had them upside down, or backwards. If you had turned them over you would see the proper tension on the plier. Try it, it's easier to see than explain
I had the "MX" version of that bike , white with yellow , vs yellow with white , years of tiding that thing , great bike
Neat little bike. I grew up on a Yamaha champ 50. Many many hours on that little bike.
Ready for the next video tearing this motor down! Can't wait to hear this thing running crisp!!
Great job on your diagnostic skills too!
Outside of winter I think your neighbors should be paying you a monthly subscription to keep the mosquitos away
Man thats nostalgia on steroids .... I had an MR50 ... looked very much the same as that ... exhaust was different ... such sexy little bikes ....
My first Bike was Green Yamaha 100 Enduro - 1972 - same pipe cover - I was 12 years old and felt like a 👑
I grew up on a 73 MX80 white tank Yellow and black design like on this tank. thing was so reliable and fun. I then graduated as I got a bit older to my Dads 76 Honda Elsinore MR250 which I still have
That's the first dirt bike I rode after the 50çc it was fast back in the 1990 's their very t9 get running
it was reminding me of the old Honda z50 i used to ride as a kid also.
