Deflection in the cylinder walls and piston/skirts might decrease.
I may be wrong [flame suit on] I don't see how a 1-8mm rod length increase would be benificial. Except to lower the rod ratio by .02-.05%, if that's the goal. Piston speed doesnt increase because you havent changed the throw on the crankshaft.


Well, heres a hint:

There is no wrist pin in my design..... smile
