We’re often asked why we don’t offer a “pod
filter” air intake kit, especially since assembling one would be simple.
After extensive testing, here’s why we don’t recommend this setup for
the V Star 1100.
The V Star 1100 uses dual Constant Velocity
(CV) carburetors designed to operate as a paired system through the
factory “black air box.” This shared chamber allows the carbs to behave
like two smaller units at low RPM, producing stronger torque, while
also acting like a larger combined carburetor at higher RPM, increasing
horsepower. Much like a 2‑into‑1 exhaust improves scavenging, the air
box allows the carbs to scavenge vacuum from each other for better overall
performance.
Unlike a bike with a single carb, the air box
stores vacuum between the V Stars dual carbs. That stored vacuum lifts
the CV slides faster and pulls fuel through the main jet more efficiently,
and much faster, causing the fuel to strike the tip of the needle harder
and improving fuel/air atomization. The result is a cleaner more combustible
air‑fuel mixture resulting in more power.
A pod filter system removes this vacuum chamber
entirely, forcing each carb to work independently. This is why pod setups
require jumping from a 112 main jet to a 150 main jet or even larger.
Without shared vacuum, the carbs need a dramatically bigger jet simply
to move the same amount of fuel. It’s the difference between drinking
through a straw versus letting liquid flow through it without suction.
The “performance gains” people feel with pod
filters are misleading. You may see a slight increase at the very top
of the RPM range once each individual carb finally generates enough
vacuum on its own. But you lose low and mid‑range performance, the RPM
range cruisers are built to operate in. The top‑end “rush” is really
just the contrast created by the loss of bottom‑end torque. By the time
you reach that RPM range, you’re shifting and dropping right back into
the weaker zone again.>
In real riding conditions, like leaving a stoplight,
a bike with a traditional performance intake accelerates harder through
the low and mid range and continues pulling into the upper RPMs. A pod‑equipped
bike only begins to catch up at the very top rpm range, and by then
you’re already shifting.
Our testing consistently shows
performance air intakes that utilize the air box produces stronger,
faster power at usable RPMs.
Pod systems on the V Star 1100 have benefited
from social media hype, but if they offered a real advantage, we would
manufacture one. We choose not to capitalize on that trend because the
data simply doesn’t support it.
Another common question is: “Which performance
cam should I install to get my bottom‑end power back after switching
to pods?” Unfortunately, once the CV carbs are converted to independent
pod operation, tuning becomes a game of whack‑a‑mole. The solution isn’t
a different cam, it’s restoring an intake system that allows the carbs
to work as designed. Only then can a performance cam deliver its intended
gains.
We hope this clarifies our position and helps
answer any questions you may have.
