Stroker Crank

Who would be interested in a stroker Crank
Greater displacement than we can get from going sideways alone.

And a Titanium Con Rod !

what the fuck is that?¿

 

[Dool]

Titanium Con Rod or Stroker Crankshaft?

It's a crazy idea, specially thinking about the work involved to pull it off, both on the development side and after on the customer side!

But I frigging like it!!!

It might have to do with the fact that I'm now deeply in love with the 500cc UCE engine and it's low chugging character....
BTW this would contraddict some of the mods we've done so far (bigger valves comes to mind)...

@Dool how did you come up with that?

 

[Dool]

Himalayan Crank is held together at the Crank Pin, the distance of this pin center to the main Bearing center is the Stroke, in our case 86mm.
With an Offset pin the center can be changed making a longer Stroke..
A new Con Rod ( that which joins the piston to the crank) is normally required to accommodate this extra Stroke.
End result is more displacement and the advantages of a long Stroke are retained.

 

[Dool]

So for example, is 5mm was possible the
Displacement is close to 500cc


Or with an 86mm piston

Close to 530cc!

Titanium Con Rod or Stroker Crankshaft?

the latter

 

[sam2019]

would that not require a new longer barrel too?

 

[Dool]

yes or a Spacer to lift it up.
