It has an HD bar and shield logo on it but no number. Any link to a how to video?

 

Looks a factory stock belt $$$ first stop is gonna be a dealer or ask for online dealer parts retailers that still carry or can find that for you , I haven't seen one in years.

Changing it will get a little involved for a beginner again hunt around online or find a factory service book for your year.

 

Would a company like BDL offer a factory replacement do you think?

 

The factory belt was 1.1/8" wide...virtually all aftermarket belts are 1.5" wide...BDL, Karata, J&p etc carries them.

Looking at the pictures of your bike, it does not show any venting for your primary case.
Inclosed primary belt drives will last a lot longer with some air flow through the primary case.

 

Very slight, if at all...
Alignment is critical...probably why the MoCo dropped belt primaries...Too Much Labor for an assembly line process...
