First glance looks kind of cool. Closer examination reveals it is actually 2 independent engines(connected by a common case) with a single carb supplying both engines. The problem becomes apparent at the end of the video when the first engine comes to a complete stop while the second continues to rotate. This configuation might provide a power increase(limited by single carb), but severe harmonic vibration problems will occur due to non-syncronization of rotating and recipricating parts.
Let me preface by saying "I'm not trying to be a dick, but...." To be a twin the pistons have to share a common journal on the crank. And, to be a "V" the pistons have to be connected to the same crankshaft. Thusly, this is not a v-twin nor a v-2. The better thing to call it may be "crossplane-2". Beyond that, the only way this engine can "work" is if both cranks are connected together and then singularly connected to a clutch, due to the fact that one piston can fire faster than the other.
this made shows pics of how he builds Indian & Exsesler motorcycles from scratch. This man can creat from a block of metal Indian motors & Exselser motors that are
exactly like the original vintage motors. He creats these bikes from nothing to the realventage motor bikes. Crazy Horse,, I hope you get this.
I'm patiently waiting for this baby to hit the market...Got a mean "Jones" to get started on my new boardtracker and gotta have this in my hand before we start to bend tubes...PLEASE get em out there !!!! This engine is AWESOME !
Sprocket isn't turning, I see no fuel tank so how's it getting fuel? China girl engines are a piece of crap. A twin one will be a double piece of crap. Don Grube will love it. He will sell a million before the complaints start coming in and then he'll say "sorry".
:O Where can I buy this? Im tired of the single cyl. china girl

I see some of my drawings a circulating around and about
Should make a nice board track bike clone.

2 single cylinder engines in 1 housing.
I am not trying to be a smart ass.
If you built it from scratch you are very good...but what is your goal?

@pencon61 I agree -somewhat like a "tandem twin" layout from a KR250.

the green line leads to the fuel tank which is out of frame, the sprocket isn't turning because the clutch is disengaged, you must be a real dumba**,
