I've always been a little concerned about much of an increase in stroke because of the increased angularity of the rod. Also, doesn't the piston pause, ever so briefly longer, at the bottom and top of its travel when stroke is increased? It would seem to me that, in a stroker, the forces applied to the bearings, rod, and wrist pin would increase as the piston "parks" at TDC and BDC and then gets yanked back into the next stroke. In otherwise identical engines, does the stroker wear piston and cylinder wall surfaces faster due to side loading from increased rod angularity? This does make for interesting thought processes. Thanks for bringing it up.
