Thanks Marcos, Dave and Bill. Thank guys!
Today I played a little bit to fine the right tuning point.
At the end, I got those values from motor checker:
But…in the next race (will be my 1st in 21.5T class, I used to race13.5) the maximum timing allowed will be 50 deg. To get those values, as you can see in the picture, I set 53-54 deg timing on the can.
Before the race, the inspector will check any motor with a digital tester to read and “lock” the timing at 50 deg.
To make the long story short: I know that the timing on can is never accurate, so I don’t know If I’m inside the rules.
Anyway, I struggled a bit with motor shimming. I found a long spacer (like a cilinder) in the pinion side of the rotor, and two little copper (brass?) shims in the sensor board side.
In the brushed era (from wich I came…) we used to rotate the rotor, and shim the two sides in order to let a little play.
I suppose now is different and the shims are related to timing adjustement.
How come can I get a proper setting? Ps I have a copper rotor inside the motor.
