So I have 2 cylinders for my MC21 that are in brand new condition apart from both having the bridge ports cracked. The original factory honing is on them and looking good. I got them this way from the previous owner as I never ran the bike but rather bought it in 500 parts. Can the bridge port just be relieved back a bit or will I have to send them both off the be welded? I know its caused by improper heating of the bike.
