- Welcome to a short gearbox insight, or how to give a broken 2-stroke engine casing a second life. The video can give you a pretty good idea of how this particular 4-speed transmission (similar to many others) works in case you are not familiar with it. It also shows the unique mechanism which JAWA engineers developed to combine kickstarter and gear lever. Same hardware is installed in older #IdealJawa or #Yezdi bikes. In this video, the gearbox is shown in action…
Thanks for watching as well as your positive comments. - วิทยาศาสตร์และเทคโนโลยี
Aussergewohnliche ! At 9:40 the demonstration of the Jawa’s dual function Gear shift lever/shaft and Kick starter lever/shaft
is very well done. *
I had a 1966 Jawa and always admired its design and overall riding experience. Valuable videos & Craftsmanship. thanks for sharing.
I know the shifter/kicker also actuated the Clutch as well on my ‘66. Amazing - three functions. Made for some nice “power-shifting” while underway and 1-2 shift front wheel “elevations” !
Really awesome bike, i had one, the only remark, I preferred the original kickstart and shift lever . Never imagine one could take a jawa to this level, keep the great work!!
Thank you. If you want to put bigger exhaust pipes on a vintage Jawa, you’ll need more space between starter lever and exhaust belly. That’s the main reason why I changed it.
Amazing vid and beautiful craftsmanship❤
Thanks for watching.
Very nice! Thank you for sharing!
Thank you, Sir.
You just get a new subscriber nice job men
Thanks Mate 👊🏼🤝
Great, thank you for sharing!
Thanks. You are welcome.
Nice work jawa gear box
Thank you.
Wow I love this video
🤟🏼👍🏻Thanks Mate
@@Quiet.Light.Engineering May I know you belong to which country? And if possible try to make a video about how to repair Jawa vehicles on our own for the basics instead depending on mechanic. And what needs to be checked if we face starting trouble etc,. You can try making this as a series. It will be very useful and thanks for your time to post these kind of videos and educating us. Much appreciated my friend. Love from Chennai, India.
Great video showing how the gearbox, kickstart and shifter works! I have a Jawa 350 (634) that doesn't go into 4th gear. Any thoughts on which parts I will need to replace? Also, can this job be done with the engine in the bike, or does it need to be removed from the frame? Having a hard time finding video's or information on this in English. Appreciate it!
Most likely you will have to remove the engine and split the casing. The JAWA gearbox is simple. It will probably be obvious what‘s broken if you have the stuff in front of you.
Siegfried, thank so much for the response. Sounds like a good winter project to take the motor out the frame, open it, try to see what needs replacing, order some parts and put 'er back together again. I am okay with taking the engine out, but before I crack the case I want to know a bit more about what I am getting myself into, so trying to find a good video or two (in English) that show the process of splitting the right hand side of the case. If you or anyone reading knows of one, please let me know. Really appreciate it!
Excelente
Super👍👍👍👍👍
Thanks for your multiple feedbacks!
Это круто и эстетично. Сидишь, отдыхаешь с бокальчиком и щелкаешь коробку долгими зимними вечерами))
👍🏼👌🏻👊🏼

Hello! I am just learning stuff and I've got a Java 250 1972 and I want to rebuild it to modern day ride.
Is it possible to swap it from 4 speed to 6 speed, and will that make a diffrence like being faster?
No, it is not easily possible to put a 6-speed gearbox into the old Jawa engine case. Better to swap the entire engine with modern hardware in this case, or go for another bike.
@@Quiet.Light.Engineering Thanks for information!
Amazing video👍👍👍👍 may i please know the sequence of gears for jawa 250?
Hi, what exactly do you mean by sequence?
I mean the sequence of gears are they 17teeth gear on main shaft with19teeth gear on lay shaft and then 20teeth gear on main shaft with 16 teeth gear on lay shaft ...is this right?
Standard sequence is as follows (without adding layshaft ratio):
1st: 12/24 2nd: 16/20 3rd: 19/17 4: 1/1
For closer ratio between 3 & 4 one can change as follows:
1st: 12/24 2nd: 17/19 3rd: 20/16 4th: 1/1
Which sequence is best and what sequence did you use in this video?
Thanks alot bro for information on both the sequence ..there is confusion as to what is right..
Wow ❤️
Thanks a lot, Mate.
Спасибо за видео,тоже хотел когда то так сделать,но не сложилось.Привет из Украины;)
Cool 👌👌👌like 👍👍👍👍
Thank you, Sir.
Je to opravdu krásné 🤤
👍. Ale taková škoda zničit kartery 🙄👎 co bych za ně dal. Nevím jak u vás ale tady má cenu kompletní motor i 15000 kč podle stavu i víc (CZ)
Thanks for watching. As you can see at the beginning the casing was broken…
@@Quiet.Light.Engineering We still take these arteries for a lot of good. No hard feelings. Otherwise you're the jawi guy to make such a runaway cannon 🙂👍
А я подумал сначала,что сейчас к другим картерам приварит эту часть с коробкой..
Спасибо за комментарий. Нет, я предпочитаю поручить сварку нескольких двигателей и т. д. Аллану Мильярду.
Кпп собрана неправильно - шестерня с насечками стоит на промвалу
Thanks for watching. This old type JAWA gearbox is correctly put together. Hardly possible to do it wrong.
