DON'T GIVE UP! That was me 5 years ago you just have to keep trying and research. With the amount of information on the internet nowadays it's like going to community college you just have to make sure you aren't reading bull (don't trust wikipedia but it can get you started).

All the things that the computer controls and how hard it is to access still makes me want to go ITB's with 6 mikuni carbs, pulley crank trigger/msd 6al/dedicated ignition system, lock the vvel open, switch in solid cam sprockets and ignore the shat out of the SES light.

I've been looking at ITBs for my L28 but it seems like the cost is hard to justify. A well designed plenum doesn't cause turbulence like the butterfly valves on each ITB produces. I think I'll stick with my triple Mikuni's....

I'd get ITB's with gate valves instead of butterflies then it's straight through. I love how much those things cost. You could probably find some large mikuni carbs with the cylindrical slide, remove the needle and float bowl, bore out the venturi for more flow as you wouldn't need it anymore, and bolt them to a 1" spacer plate that would have injector bosses in it. Don't know if they make mikuni's that big though.
