I'm going to be taking my cylinder to a machine shop to get it bored since I'm putting in a .40 over piston and rings. Back in the 70's when I was racing MX (I rode a CZ400 yellowtank), we used to mill the heads to increase compression. Anyone done that on a CR250M and if so, how much did you get them to remove? Notice improvement? Thanks, Robert |
