[QUOTE="Pete Payne, post: 1255875, member: 20445"] I am pretty sure on 02 will interchange with the 03 . Best bet is a 3mm overbore . I have built many of them in my shop . Also have built quite a few CR 144's ( yes ther is room for it ) . The problem with the 144 bore is the way the Honda exh. port is designed . To make the 144 bore work out and not make the exh port extreamly huge we have to offset the cylinder bore to the rear . Then the head gaskets like to blow because of the placement of the rear cylinder stud. So go 3mm and it will work good . [/QUOTE]
