Hey guys I on the process of rebuilding 1999 YZ 400f which had the crank rod seized. I got the rod unstuck thanks to a can of wd-40. But the bearing is shot. I picked up a 426 crank off e-bay for a steel and was hoping that I could swap that in there. Would I have to swap the cylinder as well or can I just use the crank? Thanks.
