[@thehaze1972]

@28:00 It is a good practice to align the pin of the vristpin circlip vertical to the cylinder bore because it can get fatigued by the reciprocation and break off. I also like to cut the pin shorter to have less mass wanting it to flex. It does not happen often so I am sure you won't be having any problems this time either. Really nice build, again, big thumbs up! Be interesting to see what you come up with next. :-)

I do not cease to admire your ability to convert a single-cylinder engine into a two-cylinder engine using parts from the landfill. You're just a genius, you would go to the design office with some good car - moto factory to create something new. Although you probably feel good anyway. Thank you for the interesting videos, I'm always looking forward to new releases. Good luck to you and all the best.

Another stellar job! Interesting use of rebar for shafting. Much rebar is high manganese because it's often made from "rerolled" scrap railroad rail. I like your cool self-made tooling and mill clamps too. Your aluminum casting repair skills are outstanding and should be a moneymaker.

Lntwin is a name that Ducati invented to make their engines seem different, they are just Vee Twins with marketing speil, your build are still amazing, no matter what you call them.

[@GGGMotovlog]

L twin is a specific 90° vtwin tho. V twin could be anywere from 45° or something right. To make the title more shorter than i turn scooter engine to v twin of 90° 😂

[@chris_vk3radio]

Actually the L twin name applies to a genuine 90 deg configuration, as in a right angle offset. Most manufacturers did not employ such a large angular separation between cylinders until the 1980s, with Ducati leading the way.

[@michaelbrinks8089]

It wasn't a gimmick, the rear cylinder on V twin engines gets poor airflow & always wears out 1st from overheating. The L twin configuration allows plenty of airflow to both to cylinders, fixing the issue. The air cooled L twin design is superior to air cooled V twin design.

[@metricstormtrooper]

​@@michaelbrinks8089Ducati twins had the same layout and were called vee twins till late in the life of the belt drive twins, vee six automotive engines are still called vee sixes even if they are mounted across the vehicle for front wheel drive use. Ducati makes 90 degree vee twins, they just gave them a name to appeal to young people who have no idea of the history of the Ducati layout.

[@metricstormtrooper]

​@@michaelbrinks8089they made the same engine layout for decades in twin and the rare vee four before one of the many new owners of Ducati came up with a name that would be able to copyrighted. It's Just Marketing Spiel.

Le Dan you are super genius 👍 I just love watching your videos..

[@domambocringleton2230]

Absolutely cool like every video you make. But i have one question: How do you generate Spark for both cylinders at the right timing when you only use one pickup signal???

[@CristianBulffo]

Pienso lo mismo, aunq talvez utiliza el sistema de chispa perdida como los antiguos Ford modelo t de 1910 , siempre habrá una chispa disponible en los cilindros, así q si hay compresión y mezcla habrá explosión 💥, o talvez colocoo un segundo captor magnético q yo no pude ver 🤔🤔🤔🤔

He used two CDIs for that. Maybe he modified the timing marks on the flywheel and added a second pickup coil off-camera.
