motor skiming (trueing)
Was just wondering how people skim there motors and what the tell tell signs are, eg colour of the comm itself, does it indicate overgearing or undergearing, when the begining and end of a segment is burnt/black what does this mean does it have something to do with the braking effect of the car??
Plus on a stock motor how should you skim it, as you dont see as much of the copper as you do on a modified motor, this is difficult because you cant skim right to the end without wearing down the plastic of the comm ???
