hi there, i'm about to start what i think will be a serious project, but i'm a little stuck on the dimentional side of things. i'm trying to build a 450 motor using a 400 short stroke bottom end and 450 head and cylinder. i'm not sure if you van fit the wr/yzf 450 cylinder onto the 400/426 crank case, or failingtht can the 426 cylinder be bored out to 98mm from the 95mm STD. i will be posting pics of the project as i go on the yamaha wr section if anyone is interested in watching the progress. thanks for any help in advance.
