- Only two manufacturers in the world have used a
dual split-single engine in their vehicles , but only one motorcycle manufacturer !
Many thanks to all bikers and motorcycle fans who contributed their videos to our motorcycle channel. If you have a motorcycle at home that you built yourself, or an old, interesting or unusual motorcycle that you would like to show, please send me short videos from your camera or mobile phone to: We Transfer - jawatinomoto@gmail.com
I will process your videos and publish them on our motorcycle UA-cam channel - Jawa Tino
It's so cool to see these bikes running. When I was a kid I had a Puch twingle. If I remember it was branded as a Sears. There's nothing like the smell of two stroke.
When I was a kid I had a Sears/Allstate/Puch 2-stroke twingle. Gave it away but kept my Zundapp Bella and 125 Rickman/Zundapp. I used to chief tug boats and we had some Fairbanks-Morse OPs and they have cranks that lead/lag so that the exhaust ports open first and close first.
I'd like to add that the BMW Isetta was another car to use a twingle split engine.
They should make 4cylinder Twingle hayabusas today
Excellent .
that 500 sounds cool. wb
Very nice 👍
how is that thing not vibrating like hell?
Mobil 1 synthetic grease
Why would it??? 🤔
@@dennisschell5543 the first cut model, it got two pistons, not synchronised (they don't reach top point at the same time), linked to the same tree, so it can't have individual counter weight. To me this is obviously going to create terrible vibrations. I must be wrong because otherwise engine would quickly destroy itself, but i don't understand where.
For balance it is effectively two narrow angle V-twins phased 180 degrees apart.
Used to ride an Allstate twingle... 😎
The Yankee 500 was 2 ossa 250 cylinders in a twingle configuration.
No
Honda 150 was a twingle.
Không hiểu lắm
👍
Hence thermosiphon type water-cooling?
My first motorcycle was a "Sears Allstate 175" made by Puch, I believe it was a sixty five. I paid sixty five bucks for it at about eleven, no license, rode on backstreets to get to the woods, sold it a couple years later for about the same. I thought it was pretty odd at the time, never knew it was so common. I think this is the first time I've run across something on them since about 73 or so. I only recently realized the two stroke engine was pretty much developed by Puch in Germany. When I bought it, there was a hole punched in the left side cover because the kickstarter stop was broken off. I took it to a welding shop, but the charge was fifty bucks, so I took a lump of lead and peened it from both sides and got it relatively airtight. That was when I fully understood the use of the crankcase in the air-fuel mixture cycle. it was a strange beast.
Excellent comment
A mate had a little Puch mini cycle for his son about 20 years ago
And I like the sound of your lead repair, I've made a lot of repairs and things using aluminium and steel riveted into holes much like what you're talking about
@@hodaka1000 Thanks, I hope it works for you. I was casting lead when I was about eight or nine on the kitchen stove, I still recycle metal, just poured about twenty pounds of copper, scrapping with an electric melter from amazon.

Wow.. I didn't start melting lead till I was about 13
Although I was demonstrating it to my great-nephews when they were 7 or 8
happy to say i have that bike in the garage, it was my older brother's. has 1950 miles on it.
I think with a larger water jacket for the rear cylinder, the overheating, should be resolved and modern ignition timing would help.
It's km/h, not "kph" or "kmph" or whatever, why are so many UA-camrs illiterate?
