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.

Yamaha HS1 90 twin, timing and tuning
มุมมอง 1.8K21 วันที่ผ่านมา
In this video I install new points and condensers and set the timing using a dial indicator and a light bulb. Then I pull the carbs again and install one new float and two new float bowl gaskets. This has fixed the constant seeping of the float bowls, and the new float replaces the one that was compressed.

In this video I machine the crankshaft for the 1973 Yamaha GT1 to accept thrust washers. This is done on the Jet Lathe using a homemade turning adapter that performs off center turning operations. Once the material that is required to be removed (.040 per half), then the top of the halves are milled off in the Jet milling machine so the axial measurement can be made at the big end pin location....

Boring Yamaha's smallest twin, HS1, 90cc twin
มุมมอง 2.4Kหลายเดือนก่อน
In this video I show the set up I used for boring the 1970 Yamaha HS1 90 cc twin on the Bridgeport milling machine. These cylinders are so small at 36.50 mm, that a 3/4-inch boring bar just barely fits in the cylinder. Once bored I go through fitting the piston using the Sunnen honing machine. Then I chamfer the ports and plateau hone using a ball hone for vertical side of ports chamfer and to ...

i built one similiar, would pull wheelies in all 4 gears. the 125 motor is taller, so i am anxious to see how you get the stock pipe to fit.....
Great job! I have a question You said that these bushings are screwed in Is it possible to just replace the bushing Thank you
Well explained and shown! Great video! Watching this from down under Australia. I’m trying to sort out a 74 dt360 at present!
Dale, i dont know if you mentioned this in a previous video, but what did you paint the frame with? i'm doing a '71 F6 125 right now and plan to paint the frame, but i want something tough since ill actually ride the bike too
What I use is automotive single stage acrylic urethane.
@@montana2strokeracer thanks!
Question, do you need to make sure the cylinder is straight up and down also?
Hey John, no you really don't want to go down that road. Your cylinder is aligned to the crank and rod by how it fits to the case. So you just try to maintain that orientation. The rotating assembly and piston compensates for any small differences in alignment.
@montana2strokeracer Okay, thanks.
Hello Dale! Love your videos! I have a question for you: At 30:35 - Do you have advice for the best tool to use for removing that exhaust connector ring that attaches the exhaust head to the bottom cylinder?
Hey Ashley, for most of 60,70,and 80s jap bikes I find the Williams #471 works very well, and you can slide a pipe on the end for additional leverage.
Zzzzzzzzz
I had the 1971 in black and red pinstripes as a early teen in the early seventies. Awesome machine. I’m still riding a 2022 Beta 300rr and other dirt bikes. Thanks for the ride!
Hey Dale what is that adapter you use on the F7
What am I doing when I use the adapter. If it is pulling the crank using the Tusk Crank puller, I explain that I had to make them for both sides, and I give the size of thread I think..
Just ran across your channel do you do repairs for people I have a 85 cr500 left side case half that someone JB welded around the perimeter of the crank seal curious if you do these kind of repairs
Hey Jeff, I do some repairs for folks, but I am just about full up for the winter right now, plus I have spent a lot of time in surgery and recovery, that has been limiting what I can do this year. Think I better not take any more at this time. I do appreciate you stopping by and taking a look at the channel. Much appreciated.
@ ok thank you and I will continue to watch maybe I can learn to fix it myself I do some TIG welding but my machine doesn’t do aluminum but at the price of even used parts I could get a machine for aluminum and do future repairs if need be. Thanks again hope your recovery goes well.
Hello Dale and other guys thanks again! As stated under these messages it may be the best to get rid "flash rust" and acid is neutralizing them with baking soda and rinsing the tank after that with spirit. Sometimes the tank will have a thick coat of rust and it maybe be tricky to have it removed otherwise than putting a handful of scruws in it and wrapping the tank with superlon and put the whole tank into a concrete mixer and leave it to run untill the rust is away.
Hello Dale and thanks for the tip! In Europe we don'nt have "Metal Rescue" for sale if not ordered via eBay or something like that from US. But instead we of course have other possibilities instead. The one thing You didn't mention is how to prevent "flash rust" after treatment. I had my Yamaha RD 125 1974 tank marvellously good treated and shiny inside with normal Vinegar (mild acid, aprxx. 10%) , but just the same moment when I rinsed it with water, it took "flash rust" immediately. Well, maybe "Metal Rescue" is better than Vinegar. But, like You mentioned, "Metal Rescue" contains mild acid so the problem would also be present if You are using mild acid chemicals what ever their content is? I bought also Phosphorus acid to overtake the rust problem with the tank, but it made me to hesitate if it's dangerous for skin, so I changed that to Vinegar,
Metal Rescue is not an acid, it is enzyme something or another, that's why I use it instead of the others that are acid. No flash rust with it. If you're using vinegar or something like that try sloshing around a quart of denatured alcohol after you dump the vinegar. Or perhaps a quart of baking soda mixed with water. ether one should prevent your flash.
Really enjoy your videos. Hands on is so much better than the book.
Thank you, Jim, glad you have found some value in these videos.
Excellent description of what needed to be done and execution Dale. Love the journey following along in your shop. Mike
Thanks Mike, think I have an email from you too. I am really slow getting to everything right now, just coming out of surgery and a setback, man it is slowing me down, I don't like that. I will get them answered.
How do you feel about using lithium ascorbate for anxiety relief?
Hey Dale - I've been watching your great disassembly vids on your '75 -several times- and give them 2 thumbs' up for painting the rest of the picture that the shop manuals don't cover enough. At 68, I often wonder how we wrench-turners functioned before we had TH-cam! I'm replacing the crank- and oil seals in my '73 K "green machine" TS250, hence the keen interest. It's really a solid time capsule, won at a Bring a Trailer auction a year ago - 4K miles - complete with all the adorning orig factory warning stickers ... BUT it smoked to skeeter-killing volumes, so out came the motor for crank seals. Of particular interest in the vids was your pulling the mag rotor - you had it good! You're 100% right in wondering why Suzuki chose those 120-degree wimpy 6mm boltholes. By the time I took the lower end to a dealer-recommended machine shop last week, it had defied outright every logical means I applied to removal .. 2 puller designs, 2-3 twisted-off center boltheads, torch heating, tapping... nothing. The shop ended up getting my permission to weld on a raised, threaded "step" and it finally relented. Stalled the project for months! Oddly, there was no visible damage to the shaft taper or the rotor surfaces - weird! Now in the process of breaking lose the dozen or so Phillips-head case screws in the R half to prep for the splitting. I think my 30+ y/o impact driver is worn & due to retire, as they are also acting like they're cemented I noted during final splitting preps, you didn't mention or show removing the shift drum retainer-aligning bolt, just forward of the drain plug on the R half - but noticed it removed in the footage right after separation, so I'll pull that for sure. LOVE that multi-position motor stand!! Is that commercially available, or a Dale-creation? Last "TS/TC legacy appearance" item: in '73, Suzuki went to a bulbous headlight (more like a spotlight) shell on the TS's... ugh!... and the classic '69-'72 "teacup" light that (to my memory) defined the "TS look" was no more. Or was it? After a heluva lot of EBay-ing, measuring and fitting, I have successfully retro-fitted mine with the classic '71 mount-ears and teacup headlight, complete with conversion from hard-to-find sealed beam to a 6V readily-available LED 35W bulb / mount. Eureka!! Keep you posted, if you'd like. This one's slated to go with us to the AMA VMD wknd next July in Ohio. Be safe / Dave
Thanks David, glad you have found some value from these videos, I don't know why the drum retainer removal wasn't covered, probably just an overlook while moving cameras around. Lots of things are very easily overlooked, I not a camera person, more of just a grease monkey. Nice work on the headlight, I have one I need to do something with and have never tried what you have done. You should do a video showing how you conquered that problem, sure you would get a lot of watches from that one. Thanks for watching brother.
Anxiously awaiting this SL70 project. I just started a 1972 CL70 and might want Lifan option. GET WELL SOON. Great channel and content!
Yeah, me too Chad, but it will probably be a while since I just had a setback in my recovery. Thanks for hanging out with me in the shop.
I got the 1971 Kawasaki bighorn 350 the stator is missing plus a few other parts . How does it get spark with no pulse coil ?
Hey Mike, I'm not for sure, but I do have a F5 1970 model, not all bikes use the pulse coil like Yamaha does. Or maybe they do but they just look different. I have owned it for a while but have not had it in for a freshen up yet. I really don't have much experience with the Kawasaki's. I do have a short playlist of maybe 3 or 4 videos on the F5 you might check out those, I can't really remember what all I covered, I just know it needs a lot of work, I will get it back in the shop at some point.
Top
Top?......not sure what you're talking about.
I have an alarm 70 that I swapped out the original engine for a 140 cc Chinese engine. It was very difficult to get it into the frame because the cylinder and head are longer than the 70 that I took out. It fit but didn’t slip in like the original. The original engine ran fine but only went about 35.
Yes, they aren't easy but do go in without modifications, I have watched Minibike Mike do it many times.
Just stumbled upon your video and it is a great watch! My dad used to have a 50cc Suzuki 2-stroke from 1967 and while it was small, it was good enough to zip around the street of Viet Nam with the two of us on it. One distinct feeling I remember with 2-stroke is the unforgettable, unique engine sound it has. Thank you for the trip down the memory lane, and thanks for the ride along!
Thank you.
Looks like a fun project.
Hi Mike, sure enjoy your helpful videos, unlike you I cannot find any of the Honda minis around my area, this one was bought in pieces off mostly Ebay. So, it is a project for sure. Madder of fact I have not had luck finding any four stroke Hondas from this era in my area. They are just that popular I'm assuming. Thanks for stopping by Mike.
I love your videos on the f7. I have a 74 f7. You were talking about painting the welded area, looking from the video, the color looks very similar to caterpillar yellow. Might see if you could take your fender and hold it next to a cat machine and see if its close.
Worth a try brother, thanks
👍👍👍👍👍👍👍👍👍👍👍
Thanks buddy.
Well, this will be a very cool video series! A Honda? With a Chinese engine? That's new! Great to see youo back making videos, my friend.
I know I know, Chinese, I don't even buy Chinese tools. This out in left field for sure. Still going to be a fun project.
Amazing yet again. I'm impressed
Hi Dale, if you do not have any pennies you can use some bunched up cloth rag between the teeth. It will lock up the gear train very effectively
Yes sir Kevin, have used that procedure too, in the past.
Exelent info, nice guy, clean shop!
Thank you. Stop by again, lots of motorcycle and motorcycle machine work going on here every week.
Good to see you back in the shop Dale. Super excited for this build as I'm a big fan of Honda mini's.
Thanks Mike, and I'm looking forward to this project.
I'm a huge fan of your work but Id need also a huge clothespin on my nose to purchase and use that Chinese motor. It's cheap because.......... Anyway, look forward to this build. I'm an old Honda guy so really want to see how things go
Yeah, I know, I hate the fact that I am going that way, but I don't have any engine, and this is how I can watch my pennies and still do a project. Heck the kids won't care, as long as it goes.
In the late '70's when I was training to be a motorcycle mechanic I had to fully rebuild a 2 stroke and a 4 stroke. My 2 stroke was a 71 TS90 with a 100cc motocross kit and the 4 stroke was a 71 SL 70. I bought it for $50 from a guy that used to flat track it and was moving up to a Kaw G4. I installed a Powroll 104cc bore kit in the SL. It has always had a smoking problem but the cases needed to be replaced (threw a chain) so it has been sitting almost 50 years. I have collected all the parts to restore it to mostly stock. I will be interested to see how that 125 fits in there. The cases do have bosses for the the lower mounts. Mine are stripped so I don't use them. I'm going to have to drag that thing out and do some work in it.
Awesome, sounds like a great project. Glad to see you tackle it. The 125 engine is bolt in, no mods required.
Hi Dale: Good to see you today.......Good Luck on your recovery........Hope to see you back "in the groove soon".
Yep doing good Bob, thanks a bunch.
Hi Dale, It's so lovely to see you back in the shop again. I was thinking about you and wondering when we would see you again. then today 10th November a notification popped up. This new project looks like it will be fun I will be there every step of the way. I have been watching a lot of your past videos all good my friend. take care Dale see you soon in the shop buddy.
Thank you, Brian, I am ready to get going, I just could not do nothing for the weekend video, so I gathered up all that stuff and did the introduction. Not the same as hands on grinding, welding, and boring, but I think it was accepted pretty well. All that other stuff will be coming up. Thanks again Brian.
First off I am glad your recovering from your surgery, and your moving forward on a new project that is going to be great to watch, Thank you for such great content and sharing your knowledge I am always inspired by your ideas and craftsmanship, your fan Joe.
Thank you, Joe, I am looking forward to getting back in the shop and starting this new project also. Going to be fun.
I have a SL175 that in the row of projects ! Pretty complete apart from the air filter things.
That will be a nice project. I liked the entire line of the SL models.
@@montana2strokeracer It is indeed Dale ! Too bad there's very little to find about the SL175.
Hi Dale, I hope you're feeling stronger. I'm just finishing up a restoration of one of these bikes. I had one as a kid so this has been a lot of fun. Regarding the engine mounts, there are two bolts (8 mm) attached to the bottom of the engine. It looks like someone removed these tabs on your frame. I really enjoy your channel. You do very nice work. Keep riding, Dave.
Thank you and I am much better. Yes, I have had a couple folks send me pictures of the lower bolts. I think most folks just hang them from the rear two. But I will be cutting these brackets off and reinstalling them so they will be used when I'm done. Think this will be a fun project.
The 4 speed little xr75 was surely a game changer as well, tough as hell and if you were young and crazy , surely it fit your over reving needs without blowing up
The G4 had stainless fenders,nice
When am I going to see that old early red and chrome tank Kawasaki G4 ,10 speed trail boss show up?😊
Probably when you send one this way, LOL. I haven't seen one in my locale in years.
Like many have said before me, it is great to see you back in the shop. Take all the time you need in your recovery. We need you to be healthy and showing us the way to get these projects done.
The little xr75 had a different engine design,it was a little more of a peppy engine design than the sl70s,the xr75 was had a little faster throttle response while accelerating,its the downfall of the older 50,70,90 engine design,that actually was originally hondas early moped motor design
Yeah, I like the vertical engines better myself, had a SL125 years ago, it was just nicer looking to me. Really though, the little Honda 4 strokes just never could compete with the same size 2 strokes. But they last longer for sure.
Hi Dale Good To See You Are On The Recovery Nice Little Project , I'm Glad You Are Painting The Frame, ( Not Powder Coating It ) I Would Not Waste My Money On Powder Coat, It Chips Then Gets Water Etc Underneath It And Rusts Your Frame Out. I'm Sure There Are People Who Swear By Powder Coating & They Will Think It's The Bees Knees. I Would Not Waste My Money On Powder Coating Any Bike. If I Get A Chip On The Paint , I Can Easily Fix It & Won't Cost An Arm & A Leg To Do It
No argument from me Jon, I have never powder coated anything. Paint was good enough for the factory its good enough for me. I agree it is an expense that I don't need.
Great to see you back in the workshop. Look after yourself mate. The main thing is to get back to full strength. Cheers, Peter.
Thank you, Peter, I am doing much better, heading out to the shop to start this weekend's video.
Hi Dale! It is grate to see you back with New projects. Take care yourself.
Thank you Luis
Wish you well Dale..! That's a nice project SL70 Honda coming up... Good Luck on the build ! 👍

Hey John, I do some boring, but I am pretty selective on what I take on. Send me an email and I will let you know if I can help you. userdakota@gmail.com
Good to see you back in the shop Dale. Even if for a sneak peek at your next build. Quite an inventory of parts collected to get started on this one.
Thanks Doug, doing better this week, heading out to the shop today. Yeah, this has been a good year collecting parts for this project. Now it's time to give it a go.
Nice. Good things will happen, just like they said. Jaguars, Enfields, and Jeeps are made in, or by people from India now, and Honda has been offshoring parts for more than 40 years. Great way to go.
Yeah, the aftermarket is strong on this little machine. I am sure that will help move this one along, I'm just not use to having so many good parts, I usually have to make or rebuild lots of stuff for these old bikes.
