how come the counterweight has so many balance holes? is it to save money over using a lathe to get it closer before balancing?
The crank was factory balanced for 2300 gram bobweight,actual bobweight was much lighter.
We used a 440 callies crank in a 400 block and had to make 3 trips from balancer to lathe but ended up with only one tiny balancing hole. Had to cut the counterwghts about .250. Of course that would be cost prohibative if you had to pay for the extra trips I suppose.
