Someone should come up with this for the dio engine.

That is pure sex appeal.

OMFG

sicckkkk....

Dio 125cc x Twin = 250cc of pure 2stroke madness!

I almost have the capability and engineering to do this too, but too low on funds and backed up with prjs already..

I am speachless.

What scooter does that go in??? It almost looks lika a dio engine in a way. How sexy is that. Just imagine bolting that on a pal or spree. Holy s***..

Trafic where did you get those pics? Anymore pic of that build?? I am like totally drooling.......

right click the picture and choose "copy image location" it will take to to a guys moped blog. then take off the last part of the url so you go to the main page. something like

wonder why they chose to make the cycles the same? Were they afraid if they had the cycles apposing it would break their crankshaft coupler? That's a crazy build! Bet It would be some serious fun.

Making them same only increases vibration. Making the pistons 180┬░ out would make for a smoother running motor and even out the power. Instead of one power stroke every 360┬░ as it is now, you would have a power stroke every 180┬░ making a smoother running motor. This way is harder on the drive train too.

Exactly, so I wonder why they did that? Was it to reduce torque on the coupler?

have them on the same stroke would make more torque on the coupler

Having them on the same stroke reduces the torque to nearly nil. Think of the cranks as two wheels on a live axel with posi. If both wheels are freespining with the same force, the posi doesent slip because there are no un-equal forces applied. If one wheel spins while the other doesent, the posi slips. If they alternate, you create a loading and unloading on that joint that creates an alternating torque on the joint. Thats the type of action you would get from opposing strokes.

I disagree... I think it would be less because the Forces on the two cranks would be equal and in the same direction.

I think they are on the same stroke, to simplify the timing. There is only one flywheel.

Edit: should have read closer, TJamz beat me to it.

Boom! Jackpot!

So who's going to try it first?
