Hi All,
It's been a while since this effort was initiated but I'm happy to say that the element cover seal part # 17351-374-003 is now available from Clauss Studios at the following link (scroll to bottom of page)...
http://www.claussstudios.com/id45.htmlClauss sent me a couple of samples and they fit great!! So for those of you running the original airbox go there and grab one for your bike as they have previously been "unobtainium". Thank you to Greg Clauss and SohRon for their help in making this happen.
