Some people just don't consider the learning process. It's easy to just comment what is the right thing to do, and you did a very great job by trying to get the cylinder and the piston apart. Also the smaller the piston is, the more difficult is to get it unstuck, or at least it's what I experienced. I really enjoy this series and you also shown me some tricks I didn't know about; thanks! If you ever want to get into italian mopeds engines, feel free to write me.
One old methods of 50year or so ago was to boil the engine in oil ,I’ve seen this method being used on six cylinder tank engines and vintage car engines work but is very labour intensive.👍
Use the cracked cylinder to cast a new one. Just paint it with thick paint and possibly glue a cylinder of paper in the bore. And base and deck surfaces making them thicker to allow material for machining.
I don't know why people would be giving you a hard time about destroying things. If youre anything like me. I take apart any broken things before throwing them. sometimes I fix it, sometimes I break it more, sometimes its just to investigate how it works. Youre never going to fix everything though. And I doubt it would have been fixed by anyone else anyway. So if you can afford to break it, go and give it a try. Thats how you learn.
Dear Seppo, try to say: "Raaaaaben Eikk", it's a long German A and Ike, like in spike or trike....just meaning raven oak! Old German last name. I am sure you can do it.
This has been a thoroughly entertaining and instructive series. You might try to get your hands on a Trojan Mini Motor. A late '40s into the '50s bicycle attachment that used a friction wheel on the rear tyre. An Italian design, (Mini Motore by a Signor Piatti) built under license in the UK by Trojan, which was a small car manufacturer pre WW2. I had one in the '60s and it worked just fine. Took it apart anyway just for the hell of it and broke the rings putting the cylinder back on. 15, knew nothing, no internet, end of project... My dad threw it away. Anyway, ignore the trolls and do what you have to do... 👍
Seppo is sharing his work for our education/entertainment - he isn't doing this so you can get pissy about what he's doing - it's his engine, get one of your own eh? If you have constructive and useful ideas - share them by all means - there are some smart people here - but also some smartarses and they're not so welcome. Of course they're not reading this - too busy typing one-handed...
Education, especially in a self taught matter, at times can be frustrating. But you judge things in life on aggregate. On balance you’re doing some great work. So what if the occasional endeavour goes sideways. Good luck with the reassembly.🍀🍻👍
thats so weird - rotary valves are the gold standard for high performance 2T engines. Reeds will never flow as much as a actual port will. Very reliable as well, but more complicated to seal.
Do the UK and German engines use the same thread sizes? Metric or imperial? My dim recollection is that the cyclemaster used Whitworth and BSF thread patterns, which were rapidly going out of fashion in favour of the American UNC and UNF.
Vespa and Lambretta both had rotary valve induction, the web of the big end would compress the air fuel mix which would when the piston freed up the fuel intake window of the cylinder, would shoot up into the void above the piston to then be compressed and ignited. Indian firms Bajaj and LML expanded on that with Bajaj developing the first 4 stroke scooter engines and the use of reed valves and more intake ports in the cylinder turning a 9kw engine into an 11kw engine, LML did a quid pro quo in that LML would no longer make motorbikes in return Bajaj would supply LML with precision parts (they were making them for Piaggio already, yes the cranks and stuff in ones Piaggio were made in India), the whole production line for the 4 stroke motors and Bajaj would stop making scooters and focus on small cars and motorbikes. Sadly LML went to the wall as India's government really hit the 2 stroke market there and with the influx of Chinese and Japanese mopeds and scooters LML just couldn't compete so went bust.
I mention Bajaj below and Bajaj were given licence and the presses and tooling to make Vespa's, this came from Britain as Piaggio were a bit miffed that the British built 152L2 built by Douglas of Bristol were superior quality to that from Italy, Bajaj needed a production line and Piaggio wanted an end to Douglas's superiority so pulled Douglas's licence to manufacture Vespa's and sent all of the tooling etc to India. Douglas did produce Vespa's from CKD kits from Italy, a shame as the Douglas 152L2 was the very last Douglas named 2 wheel vehicle ending a worthy name and British Vespa's became for example P200 (Douglas) on the registration. Things got bad during the late 70's mod and skinhead revival across Europe that demand for Vespa's outstripped Italian factories output so Piaggio had to buy from Bajaj a ton of stuff to make ends meet.
Heat is the only thing that can break the seal and if that nots helping well then alle the home made stuff will not help . And don't listen to the comments it's your channel do what you want
Mate, look at it this way, its a broken motor and not every repair attempt turns out the best and you are at least having a try to salvage something badly broken into something working which is prob a ton more than most these keyboard warriors have ever attempted. Also it is YOUR motor and you are fully in your rights to take a sledgehammer to it or paint it pink and use as a garden ornament... it is your property. Don't be disheartened by the more caustic of internet knowitalls, the folks that always seem to have an opinion that needs to be shoved down every orifice at every turn whether you like it or not, most of 'em have watched a couple of videos and have become "expert" overnight, I know the problems of working with alloys especially and the problems of alloy and different metals and the destruction that can come from galling, corrosion etc and sometimes a device or motor is just beyond repair even with the right tools. I'm a watchmaker by hobby and we suffer from the "patina" brigade who think a watch that is unreadable and in terrible condition should not be touched same as them in the classic car world who go misty eyed over "good honest patina" meaning your vehicle looks like a 4 wheeled pile of poo is somehow desirable? (actually my three wheeled vehicle does look like a pile o' poo BUT mechanically it is like a brand new car having replaced virtually everything mechanical with NOS parts)
I do not belive for a second it was a "accident" he destroyed the engine. More likely it was a instances of pure rage, when he realized his limitations.
Two engines = two wheel drive bike... Double the power!😅

And a little hazardous... I've considered heating oil until it's smoking and pouring it into stuck cylinders. Haven't tried it yet. Too wussy...
Ignore the haters, Seppo.
But ask them for a link to their own TH-cam channel first. 😄
Some of us are hiding on the old forums waiting for everyone to return
Interesting little engine, it will be fun to see how it turns out. Good job/ Per Lidberg Sweden
Generally the later 32 cc engine had the silver cover, BEC B1 carburetor and that Wipac three slot magneto

When your other half goes to bed, pop the parts in the dishwasher, she will never know.😂

Don't feel bad, if it's seized, fused, it's more than likely a boat anchor anyway.
3rd time lucky and less of a model boat anchor, be nice to see it running and fitted to a bicycle 😊

im about where you are with my cycle master, bought an engine that turned out to be seized then got another for spares
13:20 Looks like there is a lots of up and down play in the bearing or am I just seeing things?

Fingers crossed that third time's the charm... :D
hey dude I have a question
I am looking for a lohmann diesel airfilter
could you help me?
Thanks
Knallert, knallert knallert! 🤘
How old is that Cyclemaster?
Pronounciation of Rabeneick is like Raben (with an a like in Danish aften) dash Eick (like the English name Ike).
Do you want a workshop manual?

What are you like, do you want to kill your channel??? Never ever say the last unboxing! 🤣🤣
Make a 2 WD bike like a Citroen 2cv safari 👍

I'm glad you can ignore those comments! Commenting something like that is pretty pretentious :)

Film yourself doing it better then , and share the link to it .
