ehhhh..... The castle nut tools are a little redundant. I use a hammer and punch carefully and some light locktight sins ce you cant really set the torque with the ole' hammer. Just be careful, if your using a steel punch it can shred the outer nut if you dont pay attention.
Ohh and hey Ed, just got done with the superbike motor
Its sweet though the neighbors are a little annoyed with my "hey im just breaking in my race motor".
