Attachment 57525 what are these tunnels for in the intake and what would happen if I plugged them?
help balance intake pulses at low rpms so it trolls around and gets on plane
no , needs to be tuned up
I always thought it was for priming fuel to start it
on some engines is a good mod to make these larger or to add them when their are none but you can ruin a good intake at the same time
So do some twins. This is a Yamaha set up.

you are actually pulling from all the carbs. on a 2 cyl 1 carb set up it helps to cut a window in the intake to do this. the big briggs twins like it
