Then say what you mean! The only thing you say in your post is that i am completly wrong in my statement! It was you that mentioned forged induction .......... and so one, i just came up with examples that there has not been to many completly new design features. And think of all the billions of dollars that all car manufactorers use to develop better fuelconsuption, more power with less fuel....... in 4 strokes.

What i say is that Orion has a very very creative marketing department.

When i see the video and have read abaout the new WASP long time ago, many things comes to mind. When you see the slots in the crank that has been made, they are made to get more volumetric effiency as you say. Maybe so but i look it at a little different way. Orion says that gass flow will stop a little when the crankshaft closes and that it still want to move down the carb and fill up thees new slots. So, how does theese gasses in theese slots exit slots? Will not the bottom compression make a negative pressure to theese slots so gasses will have a problem leave slots? I think they will.

There is a positive effekt and that is lubrication of the rear bearign. balance factor of crank will also maybe be benefictial of thsi. Bottom compression will not because you have a higher volume of the crankcase. gassflow in the crankcase will be interrupted becasue the gasses from crankslots will have a completly diffrent velocety and come the opposite way of gasses that want to get up to the sylindersleeve.

To study gassflow and find materials that can expand in different ways regarding to temp is very very important. Palmaris racing is one that actually has very good ideas on how to improve engines of today.

Theese are jsut my point of view and i am not an enginer.

My point when comparing 4 strokes to 2 strokes is that it is even harder to develop and finetune 2 stroke engines! orion has suddenly came up with alot of "new" ideas that no one has never thought of. Italiens are best on two stroke engines and will still be best at it. I do not think that this has not been done before, espesially the angeled chanel in the crankshaft. So manufactores has tried this before, guarantied.


I only say that you do not invent the wheel twice, you can only make small adjsutments and material changes to it to make small steps forward. The longer evolution has come the moore difficult there is to improve.
