hehe, several options. i actually have a simonini case half...i always did, but i used a conduit pipe to try and find an option for people who don't have deep pockets. biggest carb i'd suggest with this method is the 14 dellorto. maaaaaybe the 15. have the pipe bent into a u, so it comes out the side, you'll need a hole in the frame either way you go, but a shorter u on the left side and longer on the right....i guess it should better be described as making a J shapped intake.
if you make it the right length, and the intake is close enough to the frame, it can clear the pedals completely. i ran a connection to my case half to make the carb face forward, so that i could keep my pedals also...you guys know my photography skills suck, so when i get a new camera(need to stop buying performance parts for my peds and car) i will detail all my progress
