you take a round file and use it to basically cut the gullet under the raker You dont want one cutter to have a larger open area than the others You want the chain to cut as smooth as possible Im shure every person on this site has had a chain that cut realy good and smooth, if you incorperate in the speed secrets you will have a great chain I have had chains that I fell with that hit a perfect spot and cut great and I would pull them and save them to work over for racing Also there are tricks I dont know so dont be scared of trying new things you might find a new trick and win some races so good luck And remember if you see a fast chain go look at it you might see something new but dont get to close because you might have better luck hitting on his wife , than getting a good look at his race chain!:Eye:
