- I was contacted by a fellow youtuber who wanted to know if I would be interested in his motorcycle a 1978 jawa 634 oilmaster 350. and we got together and made a deal. now it is time to see what we got for a bike and if it will run. so lets get into the repairs and diagnoses to see if it will do just that.

I was wondering at which “point” you were going to realize that the key IS the ignition on switch…😂. Really enjoyed the vid, thank you 👍
I had my eyes on the "little seal" Glad you found it.
I yelled oring!
When I saw the compressed air blow that off-I cringed-I have "lost" too many of those...
Am I the only one that saw the washer go flying??? you found it. good job.
I love your struggle with bosh ignition key :) Truth is that simple inserting key enables ignition, positions only affects lights
I like it. Im from czech republic. Jawa is hand made motorcycle very good czech iron. 2t mix in tank because oilmaster is very hard to tuning. Sorry for my english. I like it your channel 🙂
Jankyč Thanks for the information! These are interesting bikes.
Thank for the information.,...I grew up riding Jawas in Canada. It was a great time.
Yes yes premix absolutly perfect working. 🙂 oilmaster looks amazing, only looking no perfect work🤔😕
I never grew to trust any of the oil injection systems, premix was always safe though (only myself to blame if I ruined the crank!). My only Soviet bike experience was with MZ but always wanted a twin-cylinder Jawa, they sound better than an RD350 in my humble opinion.
@dan - MZ is/was east german not soviet russian. What the soviets did was copy the german Wehrmacht BMWs and named it Ural.
When you said “are you sleeping on the job” I was legit dozing off and I said out loud I’m up I’m up. Then realized what the hell was going on lmao
my rag guy used to sell me cleaned old shop rags 12 for 3 bucks. he worked at a uniform company. that was in the 80s and i forgot all about him . thanks for the reminder.
I worked at the local Jawa dealer in the 80's. I had the same bike only it was a 77.IT was one of the best bikes I ever had.
Jawa, Ogar, CZ and Eso were all competitors in the Czech motorcycle business. They finally merged and continued to build superb, durable and very reliable 2 stroke bikes. Very competitive in motocross and enduros. It's a keeper.
Two things that I love. Long videos and "Will it run?" videos. Keep up the great videos.
Me too :)
When it comes to Mustie1 its more like "It will run!"
I had a CZ 175 Trail bike in 1979 when I was a teenager. Heavy sod off road. After going through two pistons I scrapped it. This is bringing back memories. I was 14 when I stripped it down, every last nut and bolt and crankcase split. Re-bored and new piston. A lot of the parts on this look familiar.
7 mins in and I'm screaming at the screen.... "POINTS ON THE RIGHT" love Mustie videos. ..
Ignition is switched by pushing the key all the way in. To switch it off, pull the key just a little bit out, but dont pull it all the way, just a few mm - you will feel the spring tension as the key goes out. Thats what the "funky" groove on the key tip does. Turning the key left to right: 0 - lights off, 1 - parking lights, 2 headlight.
Interesting design and operation on the Jawa. I would have never looked for the kick starter as the shifter, not to mention how inserting the key turns on the ignition.
Very European
Gotta say it sounds great, didn't even put up a fight, that bike came to like it was rode yesterday, great video
Can’t believe it! 1964. Honda built the Honda CB 160 which is weirdly SO SIMILAR! I lived in PNG when they imported them...back in Australia sadly they were never imported here....I still dream of riding that bike and recall so vividly the sound and feel of it!
as soon as key is inserted, the Ignition is 'Live' .. had a few CZ/Jawa over the years !!
Does catch you out first time with a Jawa / CZ
neil mason I was going to say the same thing, turning the key is just a light switch, actually removing the key is the kill switch.
the same thing on the Manet S100 too :)
Same on old Mercedes Trucks.
The Word is Zündnagel in German.
I wrote it once, but to make sure - I will write it again. This motorcycle is very rare even here in the country of origin - Czech Republic. "Rust-o-ration" would be really bad thing to do, this bike is phenomenal and it deserves way more then that - if you are selling restored piece with registration license here in Czech, it usually goes for 3000-4000 US dollars (converted from CZK). Please, you did quite a lot rustorations lately, so please do a really, really nice bike for once. Thank you and greetings from Czech :)
Krivulda
Interesting to know, thanks. This model is even rare in CZ huh? That would explain why I couldn't find one for sale in the US. Such a different and interesting motorcycle. I'd like to check one out in person.
Agreed even not working ones cost more then cars. I'm from ex Soviet Union country called Latvia.
Krivulda Jak dlouho už Mustieho sleduješ? :)
Jakub Štěpánek SK/CZ :D dalsi fanusik
Jakub Štěpánek To vím docela přesně, první video co jsem viděl byl ten mrňavý Honda generátor, a ihned přišel odběr a od té doby jsem viděl všechny záchrany, opravy, restaurování, prostě všechno na kanále až na pár výjimek :)
I love these barn find episodes
I had a CZ 175 in the mid seventies , great machine . I didn't realise they were so rare now . We had lots of dealers selling them in the UK up until the early 1990s when they seemed to fizzle out. You never see one now. The twins like this one were very rare as most CZs sold in the UK were 125 and 175 singles , they took over from the much loved BSA Bantom when BSA production stopped.
I saw a CZ 175 when I was there it might be for sale
on most of the old JAWA motorcycles, the ignition is off when the key is pulled from the switch.its a Bosch ignition switch . when you put the key into the switch. it turns on the ignition. turning the switch only activates the lights and accessories.
I road one a couple of Jawa's in the mid 70,s i was laughing my guts up when you had the key issue no point in posting when i seen the date,
i,m 2 years to late to give any advise. Cheers & i enjoy the show.
I raced a JAWA in the late 60s it was always fun to watch people try and figuer out how to start one when they could not see kick starter
I grew up working on this motorcycles and it was painful watching the struggle … I wish I could help. But I have to admire the approach how this guy works the problem.
Local great job.
The key is not a key per se - it is a Bosch key, so it means it has to be pulled out for killing electricity. The turning switch itself only changes headlights.
The Germans strive to be different...complicating everything. Like their oil drain plugs requiring a custom shop tool. VW bug simplicity was a flash in the pan.
My friend had a Mercedes van in the early 70's and that ignition was exactly the same - key in and the ignition turned on.
Good find!
Krivulda ti is not bosch key it is pal key
Yeah, it has PAL written on it, but it is Bosch type. PAL was company focused on making accessories to vehicles, hence the name. It is abbreviaton of Automobile and planes accessories (Příslušenství pro Automobily a Letadla)
Gotta love those impact screwdrivers. Have one myself and it has got me out of trouble loads of times👍👍
They were a must have in the sixties and seventies.
That is the ultimate satisfaction. It starts and runs. Everything after that is "icing". (As long as there are no serious drive train issues).
I bought Jawa 638, 1987 year production( with engine from 1974, 634) for about 50 bucks. I couldnt start it half year, because she was in bad condition and I didnt have experience with motorcycles. The problem were two fucking wires...Now she goes like crazy and I am proud of her...Jawa is motorcycle with soul and history
I have 4 Stages of paper towels 1: dry clean dish or hand. 2: counter wipe 3: dish wash. 4: Toxic waste duty, grimy pan pre wipe!
Thanks for your videos, I’m not any kind of mechanic, but love the idea of wrenching of stuff !. You have inspired every, bought a small generator non runner from the small ads for a few bucks. Got it running today. Very pleased with myself 🙃. Thanks again. Motor bike project next !!
I found a californian who was for years in snow and rain in a garden,green al over,cleaned the carb,new ignition points an condensator (the same of old skoda cars ) and ride it for years, i love jawa !! And you foun out key gives the contact when in 😊
I always liked Jawa's and now I know why they are not sold in the states anymore. You have to pull the key out to shut off....................Really!!!! Great watching you struggle, Professor Mustie:) Thanks again, great video.
The little button on the top of the float chamber is called a tickler and it is used as a choke to flood the carb on cold start. Torchy
Biggest smile on my face when it started the first time. Great job mustie!
Hi Mustie1,
It's nice to see the Czechoslovak Jawa motorbike in America, which we already have in Slovakia as veterans, but most of them are driving today :)
it was good hangin out with you on this one...
Well done Bud!! That's a pretty wacky kick start and key!! never seen that before!!☺
The key is just like a Mercedes lorry back in 1978. The ignition key turned operated the lights, but to put the ignition on, you had to push the key down, deeper in the key barrel. I am still watching the video and have no idea if you have started it yet
That's a gift, started real fast, enjoy the long videos
Very cool I wounder how many people have been fooled by the ignition switch
Yesterday I watched several videos on softening rubber parts, soak in one part wintergreen oil (horse liniment) to 3 parts rubbing alcohol for about a week (check daily), it will swell some but return after a couple days of drying, it remains soft though.
Hahahaha. I have those rags in different stages. My son laughed so hard when you popped the question.
I believe if you remove the key entirely musty that'll kill the power
Its so sad, i do the exact same thing.
At least there was a VW in the background.....you're getting closer Rustie!
Thank God you got that key with the bike!
Sounds nice, and profitable.
Hey Mustie1,
there is nothing wrong with your Ignition.
You pusch the Key all the way in, Ignition is on. You pull the Key one nodge out, Ignition off.
That´s how it schould work.
Vicariously wrenching with Mustie.....made my day.
Tohle když dáš dohromady, tak to bude jezdit dalších sto let. Strakonická Jawa je echt gold! !!
Nepíš sem po Česky ale anglicky 👍🏽
@@filiprenebajla1976 sory. .to bych se vysral. mluvim jak mi zobák narostl. A je jen jejich problém, že neznají nejsložitější a nejkrásnější jazyk na svetě.
I believe that is a Jikov carburetor. It's sort of a copy of an Amal Monobloc as used on old British bikes. If the Spark Plugs are Pal brand they are factory. I've had a few Czech bikes.
I used to drive by an old bikers repair shop, had a sign out front: "We speak Amal."
Yes, these PAL plugs are unbelievable. Still using in my Simson S51 ... Never cleaned it, and working. I was using Brisk, and it broke after a month
Love the way 2 strokes rev up fast. Had a Kawasaki 500 back in the late 70s. Miss it. A crotch rocket it was.
rats arsed yessir. 3 cylinders smoking fast. Beat a Harley sporster in the quarter mile. Had to lean heavy over the handle bars when popping the cutch or it would wheely on top of you. 😅
I had the 750 triple many years ago. Would pass anything but a gas pump!
John Acuff awesome. The K 750 was unbelievably quick. I’m jealous!!
I have an H2 750 its insane
I do not anything about this motorcycle, but for half an hour I was yell at you to pull the key out. I glad you finally did as I said. 😂🤣😀
Impressed by how that old bike started up at the first kick after your troubleshooting it.
It took you 40 minutes to hear me yelling to pull the key out LOL. I grew up with Jawa and CZ in East Europe. I never knew these babies made it to this side of the pond as well. Looking forward to more Jawa videos!
i was saying the same thing and tbh ive never seen them before... but common sense tells you to atleast try..
JAWA shipped bikes all over the world.
At 45 minutes, you were correct that’s a “tickler” it forces the float down and dumps a little fuel into the intake. Triumphs used them a lot.
derk648 Many bing carburettors have that...
I forgot that Jawa built production bikes. That is one I have never been around. I know Jawa has built engines for speedway bikes for many years. Pretty cool bike.
Mustie's got the upper hand on these "uTuber's challenges" to see if something will run or not. Mustie's got the mental schematic for motor's so perfected he does it in his sleep. He knows the mental flowchart backwards and forwards - If this occurs, these are the steps to resolution - When I watch I learn where I might find that "kink" from Mustie's reasoning to solve my own practical issue. Thanks again Mustie for letting me live vicariously through your solutions to keep my own property running. The shipping from Dallas, Texas would be outrageous - LOL!
Nice *Mustie1* ! Been waiting for this one.
As much as I like the video I was watching, yours popped up and well.....he'll have to wait.
Nice motorcycle great to see it run again.
I have a twin screen set up and work from home and absolutely love your videos... very... therapeutic
ignition on the jawa is turned on by just putting the key in, then first click is side lights, second click is headlight.
to turn the ignition off you just pull up on the key....thats why it has the pointed ball on the end.
4 cans of Special Brew and an hour long Mustie video on such a rare Bike.What more you could ask for on a Friday night.
Bonnie
Be still my beating heart. A woman that has a few special brews and watches hour long Mustie1 videos. Thou hath found the unicorn.
Thou indeed! Welcome ye....Perfect Wench!
Good call, I was sipping some Stella and watching this one, my shitty Friday was forgotten.
Perfect comment. Nothing...absolutely nothing like a cold beverage and a Mustie video....not sure what it is?
5 cans!!
It's a ton of fun watching you work and I have no idea why. I don't care. I'm going with it.
I love the older bikes like that
12 mins in and I'm screaming "PULL THE KEY".... takes a breath
When you first blew out the carb, a small washer flew out and landed behind the water bottle on your right. BTW I'm in MD and last snow was the first time I used my snow blower. It would go into reverse but not forward, Thanks to your videos I knew to check the axle spacers and added a couple of washers on the right side. Those plastic bushings or the plastic 2" spacers must wear down after a while. It worked fine last time I used it. Great video
There was also a really tiny seal. I didn't see that one go back in.
I think we are referring to the same thing. The seal (not washer)for the bottom cap. He finds it after I made the comment. Watching the video again he did put the float cap on 180 degrees out @ 48.40 so the hole kisses the throat. I never would've thought about pulling the key out to turn it off.
I'm sitting here eating breakfast... watching you figure this bike out. I found myself wishing I had some popcorn, instead! The suspense was killing me. "When will he figure out it is the key?" When you started pushing the regulators and musing about disassembly I shouted "No, Tonto! Don't go in to town!" My roommate cracked up at that.
I have ridden with several people who had ignitions like this. But, they have gone the way of the Dodo. I think BMWs up through the late 70s is the most common you will find... the old Airheads.
Oh, I forgot... I stopped the video at 38:09 to post this.
45:15 Yes, that is a primer. It floods the chamber/throat of the carb for enriched starting... we call it the tickler for Amal carbs. I don't know what Jawa riders call it. It relieves the need for choke blacks that can malfunction!
nice to see and here the old girl run,can never mistake the sound of a jawa twin. i ran a few of these, my mums hubby ran them and we put my mum through her CBT on a '77 350 with a velorex single seat chair bunged on the side. had to put a railway sleeper in the chair for ballast !! good times. looking forward to future updates/videos.
Saw that washer blow out of the parts tin when you blew the carb out and said, oh boy - he’ll be lucky if he finds that. Of course you did - whew! Key pull to kill - interesting. So it’s a two stroke - ok.
I saw the same thing and wondered if he'd catch it. Whew is right!
I was looking at it the whole time lol, good thing it didnt hit the floor
Yep,I saw that washer too and when he started looking for it, he must have heard me yelling and saw my finger on the monitor.
Kenneth Bartlett LMAO, I have talked to the screen also but when you said you pointed I had to laugh cause I’m glad to hear I’m not the only one that does that. When I see a woodworker video, I’m constantly blowing on the screen as if it I could blow the sawdust in the video.
Yup! Was super concerned about it too.
you'll be the only one on the block driving a 78 Jawa
The tool kits on these are ALWAYS missing, finding that is pure gold!
this motorcycle is the dream of guys from the USSR)) was considered the best and coolest motorcycle! for it to work as reliably as HONDA, the owner must be a good specialist)) such models with an oil pump were not in use from the USSR at that time. I saw such a system for the first time! thanks for video!
the Tickler acts as the choke - allows excess fuel into system
pull the key up for off and push the key down for on.
That´s right. Key up=ignition off, key down=ignition on, pos.1=dim lights, pos2=headlight on. As usual on old Mercedes Benz trucks.
same for old BMW bikes and Russian copies of BMW
I love your posts. I just picked up a Briggs and Stratton self propelled lawnmower left on the street for the scrap man. It had lower bars, spark plug and air filter missing. With in 30 minutes I got it working. Spent £11 for new carb gasket, spark plug and air filter, made my own lower bars out of more street scrap for trampoline frame. I changed the oil, cleaned, sharpen and balance blade and she starts first pull and cut my grass now. The problem was the run and cut off cable had stretched and did not disengage coursing the spark plug to not spark, couple of shims sorted that out :)
Amazing discovery of operations of a Jawa.
I was shouting all the way “Pull out the key” 😂
I’m from India and I ride a Yezdi a motorcycle derived from Jawa. You will love it when you see my videos.
SWEEEEETTT.....Another fine job, thanks for sharing.
Dear mustie1: This key's nickname is "Zündnagel" (ignite nail)! Every older Bike, Truck or tractor in Europe including Eastern Europe and in parts of Asia etc.p.p. use these simple keys (or similar types). Put it in and push it down means ignition on normally. First notch (= slight turn) is parking light, 2. notch is driving light. Best regards.
P.S. I still want to mail informations about the best sealing material ever and another way to make metal look old than to use shoe polish. But I'm still not able to find your Email address in your utube channel informations as you mentioned (maybe because I only use a smartphone, have no computer?). And, last but not least, I lost a bunch of hair watching you treating Puch name and Bing bad. LOL ;-) I could have helped because nearly all of my former Mofa's/Moped's/Mokick's had Bing carburators. And, of course, there is a simple, common and cheap way to make every type and length of Bowden cables (or is it Bowden wires?) for gas, brakes or clutch at home/by yourself.
Why did this video make me so happy.
Nice getting an old bike running again
At 43:25 a little rubber washer gascet went flying when you were blowing air to dry the carburator flue right out of the magnetic pan
I came to the comments specifically to see if anyone else noticed that. :)
tattle tail
this type of bike has a typical defect: the seal on the crankshaft, which is located between the cylinders, below, fails. The engine starts producing more smoke from a cylinder, and going lean on the other. The lean cylinder will overheat and fail, killing the whole engine, if this fault is not serviced ASAP. Looks like it's the case here too. You'll need to dismantle the whole engine and crank to fix it.
LOL@leaky crankshaft seal that causes one cylinder to run lean. Dumbest thing I have ever heard pulled out of someones ass
@Agent 036 NWO still quite a few of these about in the uk! love the smell of a 2 stroke. left hand kick start did my head in when i first got one i kept trying to kick over the brake pedal.
@Agent 036 NWO come to think of it i,m sure my brothers suzuki gt250 had a left hand kick start as well.
@Agent 036 NWO this motorcycle is stil in production. But it cannot be registered so they will sell you the whole bike as a set of "spare parts"
Lol. Spent 20 mins repeating "pull the key out" before I gave up and came down here to the comments to confirm I had it right. I had to know and couldn't wait that far into the video :D. Still loving the channel Mustie
Really enjoyed that episode. 56 minuts pure joy.
I was actually dozing off when you asked if we are sleeping on the job. That was weird.
Aw hell yus, new Mustie motorcycle video
Good bike for chair work thumbs up from Scotland
The minute i saw the key I knew you had to pull out one click to deactivate the circuit. I purchased another Czech vehicle a Tatra 813 some years ago, the truck was a beast 8x8 all wheel drive 19L air cooled V12, it had the key with the bulb on the end. I killed a set of batteries (it was a 24v system) before I realized you had to pull the key out to shut off the power. Many German and some Czech vehicles of that age had those keys, Unimog’s, Magirus, and MAN trucks all seemed to have them. Don’t lose it very hard to find a replacement ! I have been impressed with Czech engineering, after all they did ‘design’ the VW Beetle before Ferdinand Porsche ran off with the design :-)
Carb (BING) and key reminds me of my '69 BMW R60/2. To turn off the ignition, remove the key. I was yelling, but I guess you didn't hear me ;o)
Same as my BMW R-28 Single Cylinder.

Must be quite a bit of cable drag to keep that valve from sliding down with the spring on it. Any time I'd ever had issues with valve stick was due to the the valve barrel having a bit of corrosion or bur on it.
there's a lot of cable on that one, with the oil pump system, the cable goes down to the pump first, then up to the carb. he needs a "cable luber" to force cleaner/lube through the cables and make sure the cam wheel on the oil pump moves freely. not all bikes have the same throttle cable layout of course.
throttle bottle He has the oiler, I’ve seen him use it on one or more of the bikes.
My first motorcycle! In 1979... Indeed better to fill with prèmix, later using the pump.
Box at the right side is voltage stabilizer. Electro-mechanic type. My 1961 Unimog 404 uses also a Bosch 24 V type.
Good luck!
Looks kind'a like an eastern European cousin to my old '68 Yamaha 180..loved that bike.
I had no idea Jawa's manufactured motorcycles.
And how did this one get to earth?
That's because you weren't born in the time when you knew what a brain was and what it did. You have been programmed not to think.....simple.
A long time ago from a galaxy far, far away.
They also produced granades and cars it was Czechoslovakian manufacturer established in 1920ties.
For anyone who didn’t get his comment, he was making a Star Wars joke as it features characters known as Jawas, who are meter-tall humanoids completely hidden behind rough cloth robes. Now I wouldn’t be surprised if George Lucas had named the Jawa characters after the motorcycle brand, though I haven’t verified that. It seems very plausible though as they were well known motorcycle brand the in the 70’s.
As to the original Jawa brand that made the motorcycle shown in the video, it was a Czech (later Czechoslovakian) manufacturer started in 1929 and was at one time (especially in the 1950’s) one of the top motorcycle manufacturers. The also made cars for a period of time too. In 1990, due to the fall of the Soviet Union, the original company saw a major loss of manufacturing and not long after closed down. In 1997 a revived version of the company called Jawa Moto was opened in the Czech Republic. Jawas have a cult following in India and In 2018, a licensing deal allowed for a Indian Manufacturer called Ideal Jawa to make models specifically for the Indian market at an Indian factory.
@@Charlesb88 thanks for all of that history.
Remove the key. Pull the key up one notch to turn off engine
power.
TY Philip! I still have a 1970 Jawa CZ 175. You have to pull the key out>
I really enjoy the old motorcycle videos. My favorites.
Kinda reminds me of working on my 1972 suzuki rv90, it has oil injection like that. The same thing happens to the rags in my dad's garage 😆 those white rags you have remind me of the cleaning rags we used in the dining halls I used to work in.
Thirty bucks for a bag of rags? I'm in the wrong business.
my woman has drive this with sidecar, with dog name struppi.
Love 2 strokes street bikes had a few in the 70s. Makes finger tingle, but at my age I'll get the tingle any way I can. Thanks for the video gonna sleep with a smile of fond memories.
it's like a time capsule full of little surprises. Makes me miss my 1966 Suzuki 150cc 2stroke. The key cylinder looks like it is mounted in a steel case on top of the forks, maybe you can remove the two bolts and it will come off so it can be cleaned and oiled. I would love to have that bike and yes, I would take my time and restore it.
