Performance air breather
Pros & Cons:
There are basically two styles of performance
air breathers for the VTX. A supercharger style and an open filter style
Super Charger Style:
Pros:
1) Looks
great on your bike.
2) Allows more air than stock
breather.
3) Fits
many different bikes.
Cons:
1) Air is forced into the carburetor with different force at different speeds not allowing you
to properly tune your carb. If you were to Dyno tune your bike, you would need to force air into the breather to get a (real
world) reading.
2) At high speeds if too much air is forced into the carburetor it will make your engine run lean and possibly overheating
the valves.
3) This style breather sticks out much further than any other breather, and may be uncomfortable
on your leg and knee.
4) Installation can be very
challenging.
5) Price $299.00
Open Filter Style:
Pros:
1) Looks great on your bike.
2) Allows
more air than stock breather.
3) Does not force air into your carburetor allowing your bike to be properly tuned.
4) Fits many different bikes.
Cons:
1) Back plate has no velocity stack.
2) Back plate has nothing to slow the air at high speeds, sometimes allowing the air to pass
the venturi so fast it actually tries to suck air out of the carburetor.
3) At any speed, if your carburetor does not get enough air, your bike will run rich and possibly
foul your spark plugs.
4) No outlets for the crank breather or pair valve. You must add a second filter for your crank.
5) Price $249 - $299
ASHFORD Open Air Breather:
Pros:
1) Looks great on your bike.
2) Velocity stack on venturi will speed up air entering the carburetor for faster throttle response.
3) Air dam running to the velocity stack slows air at all speeds, allowing the carburetor all
the air it wants.
4) Has inlets for both crank and pair valve. (plug included if pair valve has been removed)
5) Air dam on crank inlet that also works as an oil drip lip.
6) Installation is the easiest you will find anywhere. (three carb screws and a cover nut)
7) Price $99
Cons:
1) Only fits VTX 1300 (all years)
