Thanks for that info, Kit. I phoned Sean at B-C to ask him about the angle problem you mentioned. Sean informs me that his manifolds are the ONLY ones out there that do indeed have that crucial angle needed for OUR bikes. Upon further discussion it came to light that for them to fit, I need to get rid of the airbox. Now I'm seriously considering doing that before riding season because I mean it DOES make sense. So I may have opened a can of worms here but just wanted to clarify that those billet manifolds do and will fit our bikes.
