Sounds like a great ride, and it involves Pennsylvania, who knew? (I am negatively biased due to incredibly moronic and asinine family in Pottstown, I avoid the whole state )
and steam train museums and rides, sweet! I'm a sucker for old tech

I didn't run the vids to preserve my Data, but man is that tempting me
I wonder if any of the cool old 'machine museums' are around in Texas anymore
there were a few in my school daze I had to be almost literally dragged out of

"NO 'bot ! I ain't going to add no blue lights to the under carriage like your "home boys"..."

Yea, there's no need for that stuff.  
After all, you are just being practical, and doing practical stuff.

I don't mean to hi jack this thread but I can't help myself. Dave, what in the dickens did someone do to a bike with under 4000  miles on or to ruin rhe head? Let it set and idle for a week?????

  Like all projects, this one keeps growing...  
The list now includes (besides the Corbin seat, 4"FCs, K&N filter, tires and Carb work already done),  Stage 3 cam, Head machining (ports etc.), 10.5 CR piston, cam chain adjuster, tach, 1.75" exuast header and Harley muffler.   All I can say is   "Beware the Indian Thumper..."

Tell me about this one

OI, this question isn't directed at your work.  But why would someone change the cam?  It coordinates and times the valves, how much better can it get?

Best regards,

pg:   The cam will allow the valves to open further and longer allowing more air/fuel mixture into the combustion chamber and the spent/ exuast gases out. The machining of the head ports as well as the larger inner diameter of the new exuast header and muffler allows for a less restrictive air flow into and out of the combustion chamber.  The new piston (10.5 compression ratio vs. 8.5 CR stock), makes the combustion chamber more efficient and the power stroke more effective.  The end result is a more efficient and effective motor (greater horse power and torque). The cam chain adjuster and nitrated cam chain are "preventive maintenance" that I might as well do while I have it apart.  
Cam terms/ definitions:
Lift=  Amount  (how far) a valve opens from completely closed to completely open. (Rocker arms also pay a part in this function)
Duration = Time (in degrees of rotation) that a valve remains open.
The combination of "Lift" and "Duration" directly affects the amount of fuel/ air mixture drawn into the cylinder on "Intake" and conversely, how efficiently the burnt gasses can be purged from the cylinder by the exuast stroke.
