Hey, long time reader/stalker here. Finally decided to make an account to chat with a few of you experienced fellas. I’ve searched for days now, with no luck. I have a 2003 440ex I’m rebuilding because of neglect by previous owner. The original rocker cover got lost when he had it at a shop that completely dismantled the bike. I have the original head that I’d like to use, is it possible for me to just grab a used rocker cover off eBay or what not and slap it on my current cylinder head. Few things I’ve seen while searching are some people say no because Honda sells them together only for a reason, and they are machined together by Honda so can’t be mix/matched. I’m just a little concerned but can’t imagine everyone is going out and getting new heads and rocker covers together every time. Thanks!
