Main Reason for side droughts was the simple fact that I've got some here and got a lot of jets etc (and experience) from the 105, also liked the idea of the longer runners. Agree that access to the plugs would be an issue, however with just a set of throttle bodies, rather than a complete carbie, it may be possible to just remove the airbox to gain plug/coil access. having said that, just pulling the Throttle bodies off would be nothing compared to having to ensure each inlet valve is closed before removing/installing the plug (and then properly indexing it) like we have to do on the 2L!
