So, is there really a differance between the "two pulleys" on the 10% od jackshaft pulley? From the picture on Vic's website, it dam_near looks like it's the same diameter....
 
Lets see... the circumference of a pulley approximately 4" across would be 3.14 * 4 = 12.6"

A 10% pulley would have 12.6" + 1.2" = 13.8" which would have a diameter of 13.8/3.14 = 4.4" which means that it is only about 1/2" larger. You probably wouldn't be able to see that difference from a picture. :)
