So I posted some compter simulation .

Stroke 6 inches for both simulations

rod length 7.375 10 inches

MAXIMUM ENGINE RPM 3000

BEGAN PLOT (DEGREES) 0 for both

PLOT RANGE 360 degrees for both

MAXIMUM PISTON SPEED -5099 -4925

CRANK ANGLE AT MPS (DEG) 71.3 74.8

PISTON TRAVEL AT MPS (INCHES) 2.61 2.64

MAXIMUM POSITIVE PISTON ACCELERATION(MPPA):(G) 541 564

MAXIMUM NEGATIVE PISTON ACCELERATION (MNPA):(G) -1080 -998

Thought some might be interested. In the continuation. With a deck height of 12.656 the 10 inch rod is not feasible with the six inch stroke but its a simulation of a 1.2 rod ratio to a 1.6 rod ratio for a 6 inch stroke

nothing here really to talk about is there? mppa is where the rod is being stretched as the piston is being pulled down . mnpa the rod is being compressed as its leaving bdc what about a 12 inch rod for a high reving motorcycle rod ratio of 2

MPS -4860.4

CRANK ANGLE AT MPS(DEG) 76.8

piston travel at mps (inches) 2.68

MPPA :(G) 582

CRANK ANGLE AT MPPA(DEG)157.5

PISTON TRAVEL AT MPPA (INCHES) 5.83

MAXIMUMNEGATIVE PISTON ACC.(MNPA):(G) -959

This is still a six inch stroke simulated at 3000 rpms as above.
