I'm just throwing this out there because I am curious.
Jay (my builder friend) and I have tossed around the idea of wrapping the header on my Vintage Roadster bike, and haven't come to any conclusions as yet.
I know that there are a lot of opinions about how it looks on both sides, and I'm right in the middle of the road; not really sure if it will fit the look of the bike or not, but we can work that part out.
My question, really is this:
Are there any serious drawbacks to using this stuff on a Savage header?
I understand that the wrap is intended to keep the exhaust gasses hotter, and therefor increase performance ever so slightly, but the stock Savage header is DOUBLE WALLED, which is unusual to me, I've always seen single walled headers on motorcycles, SO...
Since the header is already double walled; doesn't that really do the same job as the wrap anyway? Would the wrap then be redundant, and really not have any noticeable effect on the performance at all?
OR... Worse yet; would it hold too much heat in the space between the walls of the header and cause problems THAT way?
I saw someone mention in another post that there is an air hole at the bottom of the header-where it comes together-that is supposed to allow the heat to escape from the gap between the layers, and therefor relieve any pressure build-up that might happen between the walls of the header.
Anyone know if I should be concerned about these things if I go ahead with it? Or am I just over-thinking stuff as usual?
Thanks!
