Nitrous, or fuel pump... is what I was told.
Not that I'm aware of. Not sure a need exists for one actually. The huge cast cowl is not needed until you get into the big Lectron carbs where lots of Alky is needed.
Im running the UPP boot and cast bowl on my Cutler carb. Mine clears the case but not by much. The Tyson frame i have was running a Puma with a Lectron carb. But with my Saber and the Cutler i had to cut the shock mount tube and move it back.
i also noticed that it barely clears the frame with the lectron on there. Its gonna be a tight fit when i go to put the intake on there. What does the cast cpi bowl cost?
