Nice looking parts, its clear from the pictures in the article you linked to that the seals are not clamping evenly and seal leakage is happening,,, never a good thing to have an intake leak, good way to runi your day with a holed piston, I cant help but wonder how much this effects/affects the running of these computer controlled bikes as it tries to compensate.
so 2 questions on this topic.
#1) how much for the seals and manifold flange kit?
#2) isnt there other companys such as S&S, or others offering upgraded flanges and seals?
I would have to look, but im pretty sure i saw some in the latest volume of the "Sportster Performance Handbook" by Buzzelli. I read the first 2 vols, and wading thru vol 3 right now.
regardless, looks like a well made part. thank you for supporting the industry and enthusiasts.
