Tech. . .
just a pointer. . .
Once a stock motor here was teched because it was extremely fast, they just peeked inside and everything seem normal.
He won the race and was asked to open the motor, it was teched and winds counted it was 27.
Just before they will shout that its legal, low and behold someone noticed that the com was adjusted/advance/twisted to increase the timing!
Its hard to notice but it canbe done.
And using bearings and covering them up with brass washers so they'll look like bushings
Peace and happy racing!
