How does changing the connecting rods, change the stroke? 

If you increase the stroke you have to shorten the rods or else the pistons will hit the head.  You could also get new pistons with the hole for the connecting rod pin moved.  The big end of the connecting rods could also start hitting the bottom of the cylinders.  There all kinds of problems that can start when you get into this stuff.  But its nothing that cash can't fix, if you have enough of it!

The formula for measuring displacement is (^pi/4 × bore²) × stroke × cylinders. (^pi/4 × bore²) is the area of the cylinder. The stroke (length of the cylinder) is the distance the piston travels from TDC to BDC. Ergo (I love saying ergo), increasing displacement is simply a matter of increasing the area, length, or number of cylinders.
The easiest of these is to increase the area is by boring out the cylinders.  However, boring is restricted by cylinder wall thickness, as well as spacing between cylinders.
Increasing the cylinder length by stroking the crankshaft is more complicated, as it requires offset machining of the big-end journals on the crankshaft and perhaps the conrods. Stroking is restricted by the clearance between the rotational diameter of the crankshaft and the engine block.

Hope that wasn't tooooo technical for your female mind.  

Oh, and I'm sure we can guess what Raymond grasps best!

Hmmmmmmmmmm! A very similar discussion is here: http://www.custom-car.us/basics/power-basics.aspx

I wonder which one was first. LOL

Bob, I read that whole post and couldn't find any mention of Raymond.

I love it when you talk sexie F6gal 

Stude, I could dab a little 40 wt. behind my ears, that should really get your motor running!

I think I will call the guy and ask him, he listed a phone #

Well it was relisted and still has not met reserve price.  He did provide some more detail in his second listing.... (see below)..... So what other good info did you get that supports the invested price of 30K....

2001 Valkyrie in excellent condition with a reworked engine; from a 1500cc to 130lbs of torque to wheels.

Over $30,000 invested.

New height pro cams
New head work
Cobra 3x3 - six straight exhaust pipes

I see he took out the 1700cc also
