you said that you have a leak on a plastic part between the carbs right? was your question if it's hard to get to it or to buy it? I think you can prob find the part at servicehonda.com but hell, you may be able to patch it up without taking it apart if you use the right sealant for all I know. Is it possible to take a pic at least 640x480 and with enough light to really see it. Possibly point something in a really different color (pencil, etc) at the part you are talking about and then the gurus on here may have some advice for you.
