100 KPA is = 1 atmosphere of  pressure.  When you wack the throttle open, the intake manifold pressure immediately tries go to to 100KPA, AKA high MAP or low vacuum.  Decel is usually less than 20KPA, low MAP or high vacuum, steady cruise is between 25 and 40KPA, or light load, part throttle.

Thanks, Robin thats the info I was looking for

Think of it like this

20kpa MAP is negative torque or no throttle and in a downshift
35kpa is about what idle is or 0% throttle
75kpa MAP is 75% of the available torque  or about 15% throttle.  This is about the time Harley starts ignoring the o2s and starts "bringing on the fuel"
100kpa MAP is 100% of the available torque or full throttle.

Hope this helps
