2-stroke performance engine - special JAWA piston repair

- Good day again.
This video, effectively is a result of a slightly too specialised engine part that is not available in any stock. I had the choice between a lead time of 2 or 3 months for a new, expensive customised piston or a repair and machining trial, which ended up as special as the entire engine.
For those who want to do a similar repair: The bushing press fit was 0,03 mm (oversize) which should be sufficient to keep it position. As it is not a part under static load I’d never ‘glue’ it in position, like some do.
Thanks for spending some time on this channel, as well as for you positive comments.

I like Jawa and I'm happy to see how you work with she. Perfect job. You should be a teacher at engineer school and share your nice knowledge.
Glad you're back
The ingenuity and craftsmanship is outstanding. Also added bonus of hedgehog and cat's at the shop.
Those marks on castings are probably made by air pump which fell off its holder. Every Jawa 559 has it.
Vintage JAWA. A thing of beauty a joy forever.
A home workshop with a cat, looks like heaven to me. Those Jawa's seemed pretty common back in New Zealand when I was a kid.
This was like watching piston surgery! Precise work with beautiful reward! Much respect for DIY approach. Cheers!
What a fortunate man you are. Have all the best tools to the job right 😅😅😅now
Ohh man. Well, great work, but I don't know if I would reuse said piston. It doesn't matter how well the repair is made, once broke, the structural integrity is changed forever. Thanks for sharing.
used to be a great speed way bike engine , cheers from Australia
Servus!
Asi najlepší technik mechanik čo som videl skvelé nápady a riešenia
Beautiful repairs are improvements.
I had tried the PB bush for the wrist pin before, unfortunately the machinery I have access to wasn't able to bore out the wrist pin bore true like yours, so ended up abandoning it, but watching your video gave me some new ideas on how to achieve that in a round about way.
Danke für das super Video...ich als 250ccm 2Taktfahrer kann ne Menge lernen. ❤
Really cool video with some great machining techniques. Thanks for sharing 😊
I love this kind of work! 👍💯
Krásně si s tou Jawkou hraješ 🙂 Opět dobrá práce 👌
Wow ❤...just wow 😎!! The amount of work and attention to details is really brilliant ❤❤
Very nice work! Thank you for documenting the process and showing us your critters!
