Has anyone tried building a custom header with a pipe size bigger than the common 1.25" OD primary tubes for a 400ex? I'm thinking about trying a 1.50" set-up.
I've got a 12:1 comp. 463/9i web cam FCR carb combination and I'm suspecting my HMF competition series full system may be starting to restrict me (comparatively speaking). My primary use is flat/circle track racing.
Any thoughts?
Thanks,
Brian
