Banno 479 Posted September 25, 2014 Out of curiosity are the intake manifold stud pattern for BA/BF motor same for AU? Share this post Link to post Share on other sites
Campo 869 Posted September 25, 2014 As far as I know, yeah. Think they go onto e series motors also? Share this post Link to post Share on other sites
gerg 10,871 Posted September 25, 2014 Nah the two manifolds look very similar but are different: BA-onwards have two inlet valves and a flat, oval shaped port, with manifold to suit. AU and before have circular-shaped ports. 3 Thom, XTREME KARTS XF and Clevo120Y reacted to this Share this post Link to post Share on other sites
