That's a real cool bike Dale! I'll bet you had a blast back in the day sawing the bars back and forth! Can't wait to see what pipe goes on it.

You will bave doing 41:09 thing I didn't know were possible

Aluminum penny maker.niceJo washer 😁😁

Saw it the first time

wow man what great info. picked up one of these in pretty good shape with no air leaks and it ran really good but i have serious clutch slipping. my dumb as* went and put amsoil in it and the slip got worse and the first thing i said to my friends was ill bet that synthetic made the problem worse because it was made in 74 when synthetic wasnt really a thing and they all doubted me. after i put the new clutch kit in i will be FOR SURE getting standard oil to put back in it. more years experience means you should probably listen LOL. THANK YOU SO MUCH!

Wow, does that sound good after you got it dialed in! Strangest gear shifting system I've ever seen, but you figured it out! Great work and truly educational. Thanks.

Dale. You saved my life. I rebuilt a 74 TC125 for my boss and your series helped me keep my job. Keep up the good work!

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.

hay dale i sent you an email in case your like me and never check your emails lol

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.

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

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.

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.

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.

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?

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. !
