On a Duo 17.5 with the three timing holes in the endbell, approximately how much timing does each hole give? E.g. when running in the stock hole, is that zero timing? Ten degrees? When running a speed control with timing boost, it seems useful to know how much timing is in the motor itself, but the instructions that came with the motor don't say. If you don't know the answer, could you send this question on to Jim Dieter for an answer? Thanks!

From what I understand, low timing is 10, middle is 20, high is 30.

Hi, their is no way to tell exactly how much timing their is in the motor, every speedo and motor is going to be a bit different, its not as easy and accurate as a brushed motor was where you had comm segments, brushes and a visible magnet center.
the endbell marks are 0, 10, 20, the accual timing will be around 5 degs or so more because of other variables. when tuning a motor to a normal speedo you will find that when you have too much timing in it the motor will stop pulling (like hitting a rev limiter) going down the straight. A good starting point with a 13.5 duo on a mid size track is middle hole timing, profile 7 on a Tc spec, and a 5.0 ratio. when you are doing testing with other speedos, gearing and timing make sure to moniter motor temp by pulling off before 5min just to be safe and not hurt your motor.


Korey: Thanks for jumping in.

No problem man! What you said is probably still a little more accurate though. Great finish at Reedy! Maybe I'll cya again at the IIC if I can make it.
