I just install the manifolds last night on my 07 Speedy. The air box is removed and the Freak semi installed (just the back mud plate.) The problem I ran into is that if you install the manifolds with the stems up, then there's too much raise to seat the carbs. Switching them to point down corrects that. And the other problem is length. The manifolds add another .5 inch which makes putting on the left filter impossible. So I'll be replacing my K&N will a shorter set.
What do I get? A rock solid stable platform for the carbs, and it looks great. Anything else you'll have to dyno it to know.
07 Speedy, Sceptre pipes, no AI, no snorkel, w/160 main, 42 pilot, idle mixture thumb screws, TPUSA maninfolds, K&N Pod filters
