Hey, I am trying to build my 200 m, I done a little research but not a lot.... Would like some help on confirming if I can use a crf 230 Cylinder, as I'm boring mine .075 over flat top. I need 2 thousand clearance and if my math is correct I need a 67.404 bore for a sleeve. The 230 is a 67 mm bore I believe from What I've read... Now I'm trying to mate that to my bottom end. There isn't much difference in bottom ends from a 200x so I am assuming the 230 cylinder will work. But also I have xr 200 clutches to go with it and a xr 200 cam along with a D.i.D timing chain set up. Can anyone help me with confirming or directing me to a link that would have the correct cylinder for a 200
