Il primo motore ha il tendicatena della distribuzzione a destra il secondo girando al contrario dovrebbe averlo a sinistra e stato bravo perché il secondo motore gira al contrario quindi ha dovuto pensare al camme e all'accensione . Non è stato bravo alle lavorazioni alle macchine utensili ma a come far andare il secondo motore con una rotazzione contraria . Se avesse fatto girare i 2 motori allo stesso senso con una catena oppure con un rinvio sarebbe stato più semplice . Quindi complimenti al meccanico

Since It's air cooled and the second cylinder sits behind the first one it will probably suffer overheating though. Not enough air-flow for the second cylinder I fear.

Rotax made the bmw f800 parallel twin adjustable. It figure a third rod for vibration dampening and is set up at 360° on the f800 line but 315° on the Husqvarna nuda 900 twin. Also the two bike really works differently. The BMW have multi-plexing, the nuda not.

@@4sstylz f800 is not adjustable like engine in the video because you need replace crank and camshaft to change it from 360° to 315°. If you change those parts you can modify every pallalel twin to any offset between firing. Engine in the video is adjustable because you can change angle between cylinders without any additional parts, its just unscrewing some parts and adjusting them to work differently.

The 360 works better because you have a combined intake, in this configuration there is no overlap between the two cylinders and the carburetor is able to deliver fuel and air better.

Some people just have excellent spatial reasoning skills and don't need any fancy CNC machines. I've ground a rod for an 0.010 over bearing by hand with a file and crocus cloth and the car is still going strong 14 years later. I'm definitely impressed by LeDan's work but it is also something I could do myself if I were determined to do so. I've been toying with the idea of making a pushrod boxer twin using aircraft engine cylinders. Would probably use Lycoming O-235 parts for a displacement of 117.5 ci, along with a blower, and put it in a drag bike to go up against Harleys.

I love the flexibility of the engine design to switch from 180 to 270 and 360. degree

Notice how enormously vibration free that engine is, as it has two counter rotating crankshafts!

He has major skills and is a brilliant machinist and engineer. My hat is off to him. Excellent work. 👍🏻

This is the guy that can do what I have been thinking of for 25 years. A hydraulic pump that emulate the 3 phase characteristics of electrical power. If there are three pistons at 120 degree in between, it would theoretically be an even flow and pressure of oil. The same way three phase electricity works.

You are a true mechanical,, ✨🌟✨ Could you fit one more,, 😆. I looooove the pull from 3 cylinder, 120 degree. 🥰 Nice to see that you have invested in a sandblaster box,, 👍‍‍👍‍‍. Fresh blasted aluminium with clearcoat on top looks very nice. Thank you for sharing,, 💖🙏💖

theres one small thing i all of a sudden noticed : the cam chain tensioner on one side is on the slack side of the chain and the other is on the side the chain gets pulled on by the crank , the cranks are running in opposite directions and the tensioners are both on the same side this might trow the cam timing off a little bit on the one cilinder , it can be fixed if he makes the lever so the roller sits across from where its now think the 270 ran smoothest sounded the best allso wonder if the cam can rotate backwards too think he needs to make a reverse rotation cam too or run both cams of the same crank

I'm pretty sure to make an engine run backwards you need to have a reverse grind on the cam. Pretty often in marine applications you'll have twin engines and you want one to spin counter clockwise. I'm also wondering what he did there. Turn the cam 180 end for end?

Well, now the front cylinder cam chain tensioner is on the wrong side (tension side) since the additional crank is rotating backwards. In addition to that, the rear cylinder and its head lack cooling and the front cylinder has intake and exhaust ports reversed and those are not fully equal either. So this is a nice construction, but has some issues.
