Thank you for doing this in English, anyway you can do some videos on the Piaggio moped motors, I want to build a high torque low rpm 65 to 75cc motor using Polini parts and a Polini Bravo type head. Thank you

Hi,
6% of 1/100 is indeed 6u secs but it is not 6/1000=0.006 sec.
Instead 6u sec = 6/10000 sec= 0.6m sec = 0.0006 sec
u sec - microseconds
m - miliseconds
