Dale words can't express how much I enjoy watching you bring back to life these machines that I remember during my younger days, I love your show and I hope to some day ride again thanks to you God bless you and Merry Christmas.
Thank you, Joseph, I sure appreciate the kind words. I enjoy it myself, even if it doesn't go quite right. It's just plain fun. Merry Christmas to you folks too.
as a old i mean old dirt tracker myself i cant wait to see you finish the Yamaha 360 and maybe take a quick ride, also something exotic built with the Suzuki GT 380 triple. just saying!!
Yeah, I know Frank, it is hard to find parts for the old Hurst Airhart brake system, but I am working on it. Still not sure what the 380 is destined for.
Dale, thank you for sharing your shop and your projects with everyone. These videos really take me back to the trail riding days of my early teenage years. I had a 1974 DT100B and then later on I acquired an LT2MX. The LT2 came in a series of cardboard boxes as it had been mostly disassembled. Between my father, the mechanic at the local Yamaha shop and myself we were able to get it all back together. Not as a perfect restoration but as a motocross bike that functioned properly. I can still remember the first time I started and rode it after all the work had been completed. It felt almost like I had signed with Yamaha and been given a works bike. Those were some wonderful times and I will always be grateful for them. Keep up the good work and thank you again for sharing.
Awesome story Curtis, we all have them from our youth and they are always dealing with these bikes, these bikes were our first taste of freedom. I can just imagine getting a LT2 and hitting the track for the first time. You bet, I would have felt like Gary Jones too. No argument from me.... those were the best times. Thanks for sharing your story, and thanks for hanging out with me in the shop.
Back in 74 I bought a brand new (from K&N Yamaha) TX650. Ran fine for about three months then after two or three minutes it would start to cut out on one side. Turned out to be a bad coil. Ran fine after they put in a new one. Even new stuff can go bad.
Hey Bud, yes, no argument from me, new isn't always better. It can be a real challenge troubleshooting coils at times, they sometimes change how them misbehave. Thats when the hair is pulled out. LOL
Thank you, Vincent, yes, I have had lots of problems with them, you know you take a chance when you buy used coils, but so far, I have not bought a bad one. If they are 25.00 or less, I take them home.
Wow! that job is growing legs everyday. I hope the customer gives you a Christmas bonus, plenty shops would have returned the bike with sparking points and the rings pinging. At a 'certain age' bikes/cars etc need ongoing attention, just like people😏 Best wishes for a blessed and maybe a white Christmas there in Montana.
Thanks Steve, I think I was just too close to the exhaust and the heater running and couldn't hear that ringing, but I sure could when I edited the video, it was unmistakable, rings grabbing the ports. We will check it out on the next video. I'm pretty sure there will be no white Christmas this year, it doesn't happen very often, but it does happen. Plenty of snow in the high country though. Merry Christmas to you folks too.
Hi Dale, Good video! for a lot of years, I was using a Phillips screwdriver on Japanese equipment when I should have been using a JIS screwdriver. I knew something was wrong it just didn't sink in. I wondered why some of the screws had a dot stamped on them. Rich
Hey Rich, don't feel bad I think many of us were slow to figure it out. I believe JIS is superior to the Phillips, just took a long time to conclude that.
Wow - she fired off immediately after the coil change. I'm sure I would have changed the plug and wasted some time before considering the coil - good call on that one. Camera shots are great - thanks for taking the time to readjust and repoint the camera for us viewers. The lighting is great, including on the closeups. You could see the spark deteriorate and could see the points sparking. Great shots. I could hear some zzzzzzzing, when the mic was close on the left side. Be interesting to see what you might find.
Thank you, I have had a lot of experience with these coils, I can't believe they can even sell them, I pick up all the used OEM coils I can find. I think I was too close to the exhaust and the heater running and couldn't hear that ringing sound. But I sure could when I was editing the video. It sounds like rings hanging up on the ports, going to pull the cylinder and check, I should have before, but I didn't do the bore and hone on this one someone else did, and it looked great, and I did check the clearance which was just perfect at .002. We will check it out on the next one and see, but that is what I believe it is. Sure, wouldn't be good to lose the top end after all the bottom end work we have done.
She sounds good Dale, nice work. I agree with you, those aftermarket ignition parts are a real pain. Always getting with some faulty parts right off the shelf.
Another great project! I appreciate the patience and curiosity you have in engaging with the challenges. I tend curse and swear at my DT when it doesn’t behave. Yours is the better way.
Hey Dale, that was a great video, simple educational, but the most important thing is, I'm definitely sold on not purchasing anything china cheap. Thanks again my friend.
Thanks Larry, I know the feeling, I hear on the forums of lots of folks that buy those coils, and they don't work. The hair goes up on the back of my neck when I see them, because I know they are a problem. Just never sure how that problem will be presented.
Great video brings back lots of memories my neighbor behind us bought same color bike for his kid put lots of miles on that thing simpler times lots of fun.
Dale, I watch a list of folks with various skills in rebuilding bikes and motorsport type vehicles. You by far have the most skills I've seen. It's a pleasure watching and I'll be a fan for as long as you feel like fixing, repairing or rebuilding them. Merry Christmas to you and your family!
Good job Dale. It's unusual to actually see a bad coil that doesn't have any obvious physical damage. I was really expecting it to run when you replaced that hardware store connector, but that coil was definitely the problem..
I know Jack, you never see a bad one. The only ones I see that are bad are new replacements. The connector sure was suspect to me, nothing like OEM parts even if they are used.
I was doing some electrical repairs on a friends 78 DT125, which had been maybe the EASIEST starting motorcycle ever, when it suddenly refused to start. I did all the basic checks on coils, plug replacement etc, and out of the bike I could get spark, but not while installed. You probably have run across it before, but those old shielded Yamaha plug caps unbeknownst (a big word for me) to me had a resistor in them that was removable! Turned out it had broken in 2 and would intermittently break contact with movement (Forehead Slap!!) Something I could never figure out while testing the coil for resistance (I know that's generally a waste of time), the primary and secondary readings were both within spec. But when I reversed the leads on the meter, the primary resistance read super high, which I thought indicated the prescence of a diode. But nowhere in any Yamaha manual do they mention any such thing, nor any requrement to take readings with meter connected in any particular polarity! I spent too much time thinking that was the problem, then it turned out to be nothing. Just curious if you have run into this. I'll quit bothering you now and finish watching your video; it's kind of like a cliffhanger for me at the moment! And BTW the new camera rocks!
I have Wayne, these days I replace those plug caps with the non-resistor type since plugs are now mostly resistor, it will work with resistor or non-resistor plugs. Just may make noise in your neighbors TV or radio, HA!
What the heck Dale!! Did you clean out your shop ?? You actually have room to walk around in there. (I need to do the same thing with mine). I love these little bikes. Reminds me of my daughter's little LT-80 Suzuki Quad. Microscopic machine, but stupid fast.
Hey Johnnie, yep clean her up a bit, still needs some more. It is nice to be able to walk around and not knock something over. Oh yeah, those little bikes and quads are indeed nasty.
Ive really enjoyed the GT1 80 series Dale. Im also a bit of novice but ive got some mechanical ability. Ive got a rebuild kit for my YZ80 crank and getting it all put back this week all with the tips youve shown in this video series. Thanks so much for sharing your knowledge. Is it really winter over there in Montana? Merry Christmas from Sydney Australia 🇦🇺.
Thanks Chris, glad you are enjoying this series and finding some good info you can use to rebuild your own bike. Thats what I like to hear, it makes it all worthwhile when the videos can help others. Yes, it is wintertime, but it doesn't seem too much like winter this year. Very mild winter so far. We had a couple inches of snow last month but that is it. There is snow in the high country. Temperature has been mild also; we deserve it after the last few winters that were just brutal. I had some visitors stop by the shop from Bateau Bay, New South Wales October of 2022. Had a real nice visit and went out to eat. Really nice folks and we all had a great time.
Hi Chris, thank you very much, Merry Christmas to you folks too. I have had it probably 40 years, it is a Proto 4769 and its still made, I found one on eBay about a year ago.
Wow I wish Frank, the silver play button from TH-cam is presented to folks that have acquired 100,000 subscribers. So, I only need 92,000 more. I am blown away that I have 8000 folks that want to watch my little channel. I am truly blessed.
Mr. Dale, I have a problem with my 2 stroke motorcycle. 1.When i cold start the motorcycle with the coke on. it revs high. It also revs high when i on the choke. 2. After closing the coke ,it idles like a normal condition. 3. When i put the motorcycle on side stand or maybe like lean the motorcycle it stalls. I don't know but i am following the manual. It is a mikuni vm26 carb. Is this a problem of the float height, should i increase or decrease the float? And also i increased the height of the motorcycle is this causing the problem? Please. I want your help😢
Sorry you are having problems with your bike, of course the revs will be a little higher when the choke is on. But not too high, my first though would be an air leak from a crankshaft seal, but when you said its normal at idle with the choke off, I'm not so sure. You might try adjusting the float, not sure what bike it is, but when I don't have specifications, I try to level the float arms with the float bowl gasket surface without the gasket, those two should be parallel with one another. If that doesn't do it, you probably should do an engine leak down check to make sure your engine is sealed. Best of luck with your repair and thanks for hanging out in the shop with me.
@montana2strokeracer thanks for replying mr.dale. I recently installed some new piston rings. The compression is good. No leaks from the head or the crank seal,there was some leak in the bend pipe I repaired it. Is my motorcycle going through a break in process. will it consume more fuel and struggle to idle or tune till the process is done. Can you recommend what should I do and not do? Some extra points:the motorcycle starts in 2 3 kicks easily(very strong blue spark). I mixed 30ml 2t in 500ml gasoline is this a good mixture for the break in process or should I use the 2T pump instead? Can you also tell me the normal things to expect and look out during the break in process. Thank you! You are a life saver Mr.Dale
Dale words can't express how much I enjoy watching you bring back to life these machines that I remember during my younger days, I love your show and I hope to some day ride again thanks to you God bless you and Merry Christmas.
I couldn’t agree more!
Thank you, Joseph, I sure appreciate the kind words. I enjoy it myself, even if it doesn't go quite right. It's just plain fun. Merry Christmas to you folks too.
Thank you, Troy, Merry Christmas my friend

The back of the shop sure is clean.
Moved the car out John, it was just to cluttered.
Great Video, Dale. The new camera is good. We saw the weak spark. The autofocus is better. You are truly the master of old two strokes.
Thanks John, I am learning more about the camera every day. It is an improvement over the GoPro for most of the work I do.
Dale, thank you for sharing your shop and your projects with everyone. These videos really take me back to the trail riding days of my early teenage years.

Congratulations on the 8k plus subscribers Dale! Well deserved.
Thanks Graham, they are adding up slowly, I can't believe there are that many folks that still mess with these old bikes.
Back in 74 I bought a brand new (from K&N Yamaha) TX650. Ran fine for about three months then after two or three minutes it would start to cut out on one side. Turned out to be a bad coil. Ran fine after they put in a new one. Even new stuff can go bad.
Hey Bud, yes, no argument from me, new isn't always better. It can be a real challenge troubleshooting coils at times, they sometimes change how them misbehave. Thats when the hair is pulled out. LOL
Another nice video dr. Dale. Try to learn as much as I can from you 😂🙏. I’m working on Yr1 & hopefully finished before summer. Thanks & God bless you.
Thank you so much, best of luck restoring your YR1, man I would like to find one of those.
Sounds great Dale. That coil looked like trouble as soon as you revealed the dodgy crimp on terminal.
Best wishes, Dean.
Thanks Dean, yes, those things are problematic in almost every instance. Merry Christmas to you guys.
@montana2strokeracer Merry Christmas to you too Dale. I hope you all have a lovely time.
Thanks buddy.
Wonderful rebuild on a lovely little bike. Nice piece work of Dale. I love watching these videos.
Cheers, Peter.
Thanks Peter, it is a cool little bike, I'm enjoying working with it.
Lovely little machine Dale old school.
I have had so much trouble with pattern coils like you.
Just proves that the Japanese parts are Quality
Thank you, Vincent, yes, I have had lots of problems with them, you know you take a chance when you buy used coils, but so far, I have not bought a bad one. If they are 25.00 or less, I take them home.

great job dale as always great spot with the coil little run out give it a clear out be sweet as next video please
Thanks Mark, those coils are a big headache to me and many others.
She sounds good Dale, nice work. I agree with you, those aftermarket ignition parts are a real pain. Always getting with some faulty parts right off the shelf.
You got that right Dave, the aftermarket is needed for sure, but I sure wish they would watch their quality control.
Great diagnostic skills to find that coil issue. It was no fluke, but experience prevails! Keep up the superb work and showing us the way to do it.
Thanks Pete, not the first time one of those Chinese's coils tried to bite me. Believe me it doesn't always go that easy.
Another great project! I appreciate the patience and curiosity you have in engaging with the challenges. I tend curse and swear at my DT when it doesn’t behave. Yours is the better way.
Thanks John, I want too really bad sometimes, trying to be a better person, it's a challenge. LOL
Hey Dale, that was a great video, simple educational, but the most important thing is, I'm definitely sold on not purchasing anything china cheap. Thanks again my friend.
Thanks Larry, I know the feeling, I hear on the forums of lots of folks that buy those coils, and they don't work. The hair goes up on the back of my neck when I see them, because I know they are a problem. Just never sure how that problem will be presented.
Another great video Dale! Love the clarity of the new camera.😁
Thanks Steve, I am learning more about the camera every day. Hope the videos will continue to improve.
Another great video, thank you Dale. Glad you're feeling better and hope you have a Merry Christmas Brother!!
Thanks Robert, I am feeling tip top again. Merry Christmas to you also, will be a good one here.
I love your videos! Great work!
Thank you so much. Sure, appreciate you taking the time to watch them.
Another top job Dale , once again a pleasure to watch, looking forward to the SL70 build.😊
Thanks Darren, will be starting the SL70 pretty soon.
Great video brings back lots of memories my neighbor behind us bought same color bike for his kid put lots of miles on that thing simpler times lots of fun.
Awesome, we all have those memories that these bikes unlock. You are right my friend simple times they were.
34:14, I call that sort of connector a "crimp on, drop off" connector.
Amen brother, no argument from me.
Good job brother. Sounds good.
Thanks Cain but looks like I am going to have to pull the cylinder back off, sounds like the rings are grabbing the ports.
@ that sucks. Merry Christmas brother.
Merry Christmas to you folks.
Dale, I watch a list of folks with various skills in rebuilding bikes and motorsport type vehicles. You by far have the most skills I've seen. It's a pleasure watching and I'll be a fan for as long as you feel like fixing, repairing or rebuilding them. Merry Christmas to you and your family!
Thank you, Andrew, your too kind. Merry Christmas to you folks too.
Quick diagnosis on the coil, Dale. Great to hear it run. I'm sure you'll sort the rest out.
Thanks Doug, yep got to chamfer some ports, sounds kind of ringy in the video.
Good job Dale. It's unusual to actually see a bad coil that doesn't have any obvious physical damage. I was really expecting it to run when you replaced that hardware store connector, but that coil was definitely the problem..

I would love to find one of those to cruse around town on.
You should have one Don. To compliment the rest of your collection. And to ride around town.

You Should Have An Electric Fan Blowing On The Engine
Thank you, I have an exhaust fan pulling air through and smoke out of the shop, its 40 degrees in the shop. It's fine.
Nice work Dale. Merry Christmas! Where did you get your 1/4" handled bit driver? Is it a Craftsman? Nice tool.
Hi Chris, thank you very much, Merry Christmas to you folks too. I have had it probably 40 years, it is a Proto 4769 and its still made, I found one on eBay about a year ago.
Dale its to early, but lets get to work. 2K more subs and you can show a TH-cam plaque on the wall. can i subscribe twice? LOL
Wow I wish Frank, the silver play button from TH-cam is presented to folks that have acquired 100,000 subscribers. So, I only need 92,000 more. I am blown away that I have 8000 folks that want to watch my little channel. I am truly blessed.
