I'd pop out the snorkel to aid inhaling.
It can be put right back in if you don't like it.
I'd guess you'll like more airflow as that's what's happening on the other side of the head.
That'll keep a decently balanced and efficient stage one.
Easier breathing on both ends, keep the element clean, and one
washer is fine. Sounds like a great setup, and mileage might even
go up a bit from the engine not working against itself as hard. The idle screw
might be helped by coming out another 1/3 to 1/2 turn. (all of us who have done this
are at 1 1/2 to 2 turns.
All engines have to work against themselves to run. There's friction, valvetrain drive,
valvespring pressure, and the largest of all, the compression stroke. Plus, we have
a touch of drag on the doo chain too. A combustion engine doesn't need any more
drag on it by forcing itself to inhale and exhale through a straw. (Which is the easiest
and cheapest way to meet EPA emissions maximums)
Enjoy the bike and the new pipe !!
PS. If you do no mods whatsoever it probably won't hurt a thing, either with
your baffle (quiet core) in place.
