Dobry vecer. Dakujem, moc som si zaspominal. Profi praca a kvalitne video. Tesim sa na pokracovanie.

[@BackInTimeSK]

Ďakujem veľmi pekne. Medzitým som spravil ďalšie dva videá: kzbin.info/www/bejne/eKLdgqhtnLyAjK8 kzbin.info/www/bejne/nICYgniDeLR4gtE

[@vladimirzurek9337]

Super video , mnohým s opravou 90-tky pomůže.

[@BackInTimeSK]

Ďakujem!

[@jjcale1976]

Niesamowite że produkowaliscie tak nowoczesny i wydajny silnik ponad 50 lat temu💪

[@bettyna4624]

Měl jsem to, po dvou letech trápení se ani nedalo prodat. Říkalo se tomu Slovenská pomsta na Českým národě.

[@BackInTimeSK]

Tieto motory boli nadčasové, ale sa nevyhli detským chorobám. Dnes sú už tieto motorky vyhľadávané.

[@pavel.m776]

@@BackInTimeSK Žádné dětské choroby až na jednu známou věc neměly. Byly to opravdu špičkové nadčasové motory s úžasnou životností. Problémy tvořili ti, co je ničili při neodborných opravách.

piekne video :)

Nemýlim sa ak budem tvrdiť, že tie podložky pod segerkami, pri rozoberaní spojky, boli založené zle???

Nemusíte ďakovať veď je to pravda

[@zoltannagy7285]

Good job, asi to nerobil prvý krát.

[@BackInTimeSK]

Ďakujem veľmi pekne!

[@vaclavpolivka4638]

Perfektní a poučné video. Jak dostanete to ložisko ze slepé díry? Stačí nahřát karter a vyklepnout? Měl jsem s tím problém u Tatrana. To je podobný ekzot.

[@BackInTimeSK]

Ukážem to v ďalšom videu o motore. Princíp bude rovnaký ako keď vyberám ložisko z kolesa.

[@gabrielsevela7034]

Zalomit krúžok pri demontáži valca sa mi pri J90 podarilo už dva krát 😂

[@deyohn]

Hello, I'm not sure if you read your comments, but I have a question regarding the screw you explain at 10:40. I don't understand Czech, but from what I understand from your video and random stuff I read online, it's somehow connected to the starting mechanism (startovaci segment), but I don't quite understand how. I do have a problem with my 90's kickstart slipping when kicked fast, so can't really start it that way and I would like to understand it a bit more, before I even attempt to take apart the engine to see what's wrong inside. Another question I would have is how do you disassemble the shaft of the contact breaker (hriadeľka prerušovača), which stays on the clutch cover. I need to replace the gasket on it, as the oil is leaking into the contact breaker part. Is it just pressed together or something? Although I don't understand much of your explanation, the video is still very helpful, so I would like to thank you for making it and look forward to a possible engine assembly or any other Jawa 90 videos you might make. 👍

[@BackInTimeSK]

In the next video about the engine I will show how the starter works and the lower left bolt 10:40 catches the starter wheel 26:11 when the lever is in the up position. If you don't have a broken return spring 26:38, then there is nothing else to go wrong. I will show it in the next video. The interrupter cam is captured with a cotter pin. After its removal, the rod is pushed into the inner side. I hope that I have helped you and I am glad that even foreign language viewers find the video helpful.

[@deyohn]

@@BackInTimeSK Sorry, I did not get a notification about your reply. Thank you for your explanation, it did help me understand how the engine works more. As for the interrupter cam, I already tested removing it on a spare clutch cover I had, so learned how to take off the interrupter cam properly the hard way. Luckily I do have spares and the bit I ruined can be tig welded back on without a problem anyway. I imagine there are quite a few people from other countries that watch your vids and they are a great help for any renovation work, probably overseas as well, since they had Trail, at least as far as the 90s are concerned. I'm actually waiting for the engine assembly video before I start disassembling mine and will follow it closely, as soon as I get all the bearings and gaskets for it. I do kinda wish there were english subtitles, as the remarks regarding the position/direction of parts are really important, but even just seeing how the disassembly/assembly looks is way more that one could wish for and the bits and pieces I can understand help as well, so thanks again. I would have another question as well, though, this one more general one, so I would be ready any bigger problems I might come on to with my bike. Which trouble/problems did the Jawa 90 have in general for people to "dislike" them back then so much? I did read on Czech forums that there was trouble with the design of the interrupter cam and the contact breakers both breaking often as well as the spring on the breaker being too weak at higher RPMS, so double spring was recommended. I can avoid those problems with Vape, but there's always someone somewhere that says it had electric/ignition problems, so would like to see if that's true. It is a fun little motorcycle, so would like to take care of it properly and also try to fix the childhood diseases you mentioned in another comment before they come bite me in the ass.

[@rychlabeta6322]

Vyborne video. Bude prosim video aj ku skladaniu?

[@BackInTimeSK]

Bude. Pomaly sa na tom pracuje.

[@mareksnopko]

Super video, ako to vyzerá s videom ku skladaniu?

[@petervanik6648]

Zdravím vás. Prosím načo slúži tá pružina pod magnetom?

[@BackInTimeSK]

Pružina pritláča unášač rotačného šupátka, ktorý je len nasunutý na čape kľukovky.

[@abelfilo7416]

Ojnicu budete dávať pôvodnú na repas alebo japonca?

[@BackInTimeSK]

Ojnica bude repas.

[@Mikiseman86]

Aké ložiská dávate do prevodoviek?

[@BackInTimeSK]

V rámci ponuky kvalitnejších ložísk miestneho obchodu pôjdu na kľukovku SNR, prevodovka SNR a NSK, hriadeľka vačky zapaľovania NSK, kolesá + rozeta ZVL.
