Sharing my motorcycle repairs, and motorcycle restorations with others. My interests are in 1960's and 1970's Japanese made motorcycles, mostly dirt bikes, dual purpose, and street scramblers of the era. You will see full restorations, engine work, machine work, welding and painting, all having to do with these older bikes. Follow along, I want you to hang out with me in my shop. I will show you how to repair components, not just replace parts. Based in Montana USA.

My buddy ran one of those champion frames back in the 70’s with a 75 Yamaha MX250b motor. Good times.
Do you sell them already made ?
Maybe these forks are a tad thicker where the axel goes thru than the originals are.
Good job brother.
That's a mean looking bike Dale, I bet it was fun (terrifying) to race. I like the adjustable steering stem system, ingenious. Best wishes, Dean.
Great video Dale: I have only owned two new motorcycles, The first was a 73 Yamaha 360MX. It was a great bike with automatic compression release and omni balancer. Great in the desert but way too much for me.
Cool bike , with great history !thanks for the video .
Looking good Dale. Gosh, you've a few projects on the go! Must say I'm enjoying them all. Cheers, Peter.
thats a nice bike dale carnt wait to see it finished great work as always next video please
> laugh riot foot in mouth your fixing stuff thats been sub-standard for years almost explains all those jap bikes youve spent lots of quality machine time on....being a euro guy, its my opinion yamaha's rolled off the factory floor that way.
WOW nice frame, reminds me of myself building another chopper, good job dale...
That is such a sweet bike, I would love to run that thing around a track.
the front tire looks like a Duro HF, that's what i have on my Honda XL-250 TT-special.
I would have been that guy to turn down the forks lol, I like ur work , I watched the whole video, I have a RZ350 stock bore ,I have 64.25 mitaka pistons I bought, would you be able to bore my cylinders for my new pistons? I have a brand new crank I bought, just don’t trust anyone locally to do the cylinders, I know tolerance make a huge difference,and you seem to be the man who knows this
We are too old to push start 🤣
Fantastic project Dale
Awesome project Dale! Would have enjoyed seeing you slidin' sideways and slingin' dirt!
lots of guys are making what is called a street tracker, most look like your bike, and there ready to hit the flat track, but have small hidden lights and a registration/license somewhere out of sight. really cool old school look IMHO. love the idea of paying homage to the old tracker days.
Dale this is just awesome , my Heroes growing up were the greatest Flat Trackers of all time IMO , Dick Mann , Bart Markel , Fred Nix , Gary Nixon and of course later Kenny Roberts , and many more , an absolute outstanding form of racing . Moto X really took over but I still love flat track just don't love the new water cooled bikes , just not the same . Push start ,rigid frames and no brakes Yee Haw !
My life long friend raced flat track in Central California and at one time had a "Blue Plate". I grew up in Paso Robles, California in the early 70's and back then flat track was big. Local Yamaha dealership owned by Joe Brown "Browns Cycles" sponsored his son Joey Brown that raced 1/2 and 1 mile. He came close to beating Kenny Roberts a time or two! Joey Brown has since passed away but his son now owns the dealership. They had a falling out with Yamaha for some reason and now only sell BETA's.
Raced (motocross) one of 1st 360 Yamaha’s in Japan in early 1970. I raced in the 125cc, 250cc & the unlimited classes. Really a great time in my life.
Yes that frame is cool Peace out
Dale if your motor is a RT1 without reeds I have a good piston put away you can have. I’ll have to get it out to see if it is stock or over size. Let me know if you need it and check on it
bet if you get this bike running it will open up a few eyes, power and sound i mean.
yeah!!! now were talking, a fabulous past for both of us ,long live flat track racing!
Heading out for the day Dale. Will watch this evening😀
😉😉😉😉🏈
That's a pretty cool project there Dale! One of those hidden gems eh? That makes it number 10. 😊
Thanks Dale , when i saw that Champion i thought oh boy a frame for the 380 . But this was good to see . The nickle frame looks great Dale . I have never rode a Champion . I think at that time I had my DMR Ossa . Great choice for a vid Dale ! Thanks for all your hard work .
Here.
Enjoyed your videos very much. My first bike was a 65 Yamaha 55cc, which I bought in 1966 before I had my license for $75 and took it apart many times for fun. Drove it to school and work rain or snow for a couple of years before replacing it with a Twin Jet 100. Many years and motorcycles later I am still riding. Thank you for your videos.
Thanks for the kind words my friend, my first bike was the Campus 60, I probably had it a couple years then moved on to the 100 also. I still enjoy riding once and awhile, but my real enjoyment is in the maintenance and machining to repair these bikes. I am just amazed at how many other guys and gals enjoy the same, I never would have thought there were that many folks that wanted to watch this kind of stuff. I remember having only 10 subscribers and thinking boy this isn't going anywhere, but here I am around 6500, still a small channel but still growing. I thank you for watching it is fun thing to do in my retirement, and I am so glad to see so many others out there still riding and wrenching on the old bikes.
hay dale i sent you an email in case your like me and never check your emails lol
Think I replied to that one.
@@montana2strokeracer yep
Lol Dale, I thought I was gonna have to jinx your bike and make you take apart the clutch basket. I'm sure you watched my video where mine gave me fits. I got it working fine, but I hear gear whine. Which I didn't think was normal since I don't hear that on any other bikes or even the Trailmaster 80 (which is basically the same bike). But I noticed yours makes the same sound, so I'm guessing it's all good? But definitely thank you for the 2mm washer fix for the shifting. My Trailmaster does the same thing and I kinda put that bike to the side because I couldn't figure out the cryptic info about the concentric nut and my adjustments of said nut failed. Now I'll get the Trailmaster out and give it a whirl again. So thanks for the video and thank you very much for the tip. I hope you guys are doing great.
Hey Greg, yes please don't jinx my bike, it was a real bugger trying to figure it out. Think a lot of it was luck tell you the truth. Yes, I couldn't see much difference with the excentric bolt adjustment, the real difference was with the washer on the push rod in the sprocket. I bet you can figure it out, and yes, the wine in low gear is normal. We are doing fine here with summer finally getting here. Hope you folks are enjoying your summer also. Take care Greg, watching for your new video adjusting that shifter, or anything else you put out.
Excellent work that reflects in your mechanical knowledge! !
We used to straighten cyl rods (solid core) for Cat excavators in the day. We always warmed them up to 60-80 degrees C in a hot batch before pressing them. I know the tubes on these forks are hollow so preheating may be counterproductive. I assume you checked the location of the bend with a straight edge to see if it is a full length bend or a localized bend at the mid way point. Very good instructive process all the same, thanks............
31:00 already subscribed on my second account as well
Holy cow, that is awesome, I never knew folks had two KZread accounts, I hope there are more like you. Thanks Scott.
@@montana2strokeraceroh no problem, happy to help. I have a second email that I use, and that also creates a KZread account so thats how it all happened.
I had never heard of a W.A.G. until today! Thanks for explaining what it is and I learn something new from every video! Great job on the little bike and I am looking forward to the next installment.
Well Pete I am sorry you learned that from me. It is about as ruff of language as I use. Guess I learned it from the military. Been having fun with this little bike, the series has been well received, but I really don't understand why. Most folks seem to like the 70's bikes better.
Back in the day, a buddy of mine had a brand new Twin Jet 100 - A Yamaha 2 stroke twin even with electric start. I'm sure this was a predecessor or a cousin.
Yes, you are right the 100 was the first twin imported, the 90 as I understand it was imported for some states that require 16-year-olds to have a bike with less than 5 hp. The 90 was detuned by longer slides in the carbs, most folks change them to 100 slides and behold 10 hp.
As someone who has laced a lot of rims, but only does it once or twice a year - I can definitely tell you that you are doing it wrong. You have to lace it incorrectly and start over a minimum of one time and it really helps to spend about a half hour loosening the nipples when you think you are tightening them really throw it off.
Well Lee, I have had to do them over before, not what I call fun. It seems like the last couple years I have done way north of 25 wheels, not my favorite task, but it does pay the bills.
Dale, Dale, I am totally puzzled regarding the clutch axle push rod lever on the 1974 MX250. The engine is out of the frame. The oil seal needed to be replaced. I removed the clutch axle push rod lever to replace the seal. After reinstalling it there is only about 1/2” movement (rotation) on the lever at the bottom of the engine. Is this normal? It seems like the lever that the clutch cable attaches to should have more back and forth movement. Suggestions?
Hi there, I have to been honest with you, I just have not worked on any of the later DT/MX bikes with the lower lever clutch actuator. I really have not experience north of 1973. I did look at the parts breakdown from Yamaha, I see they no longer use a ball between the actuator and the rod. Its seems that maybe the installation of the lever may be key.......sorry can't be more help.
Cross reference if a Mikuni carb is available
Yikes lots of gunk built up in that carb will cause much of the problem. Spraying lots of carb cleaner and air blow it out ..😊
Have you checked the jets and needle in the carburetor and two other things that may help is to get an NGK plug and check also that you have a correct air filter and clean air box, add 4 ounces of Chevron Techron fuel additive to help clean the carb further and that maybe helpful. When you do get a quality chain I do suggest a new rear and front sprocket. Thank you for the great video Sir. !
Excellent video Dale, I would never have thought the process would be successful but it is. Well done goodonyou and thanks.........
Well, me either, but I do have several that I repaired, and they are all still running. There really is not a lot of pressure in those lines.
great video as always dale like you say it will never pull any trees up but great little bike saved another one keep up the great work next video please
Nope the trees are safe here.
Hey Dale, Try timing it at 1.8mm btc. We had a shop in the 60s and that's what worked for us.
Hey Bart, oh I see the high-speed tune as specified in the manual is the way to go. It sure needs something, I was not sure if I should go that route or not. That may correct what I thought was a over rich condition by letting it breath a bit more. Thanks for the tip, much appreciated.
That hub looks amazing. Is that refurbished or NOS?
No Lee, it is refurbished, I have a paint process I use on them.
Nice series of videos for the 60. Always something to learn from watching. I like the quick diagnosis and repair. 35 mph... that 90 mph speedometer is overly optimistic. Great sounding little bike!
Thanks Doug, you are right for sure....don't think we will have to worry about breaking the speedo on this one.
Seriously creative way to add a filter screen! Another wonderful video filled with tips and tricks! Thanks!
Thanks Jim, I just kind of like that screen in the tank, I have found marbles in tanks before.....they can plug a hole without a screen.
check them points again dale, on a new adjustment they can wear real quick when they ain't ben run in years,, however you are going 2 put in new ones soon so you will know that ain't the problem,, glad you made it back home and glad i went along 4 the ride...
Right on James, waiting on the new set to come in. Will be back on the little 60 to set them up soon.
