Maxair Predator Pro Kit for the Yamaha V Star 1100 - FAQ
What is the Maxair Predator Pro and why should I purchase it for my V Star
The Predator Pro is
a filter system that eliminates the stock
restrictive air chamber and snorkel under the tank, allowing for maximum
airflow and power gains. This kit has become well known among V Star 1100
aficionados, as the must have for the best power, while retaining real world
Predator kit is both an air filter system and a re-jetting system? Yes
it is a complete system, with everything you need (minus tools) for install
and tuning. Also included, are full color instructions and access to our
technical support forum where we will "hold your" hand through the
- I have heard about
"POD kits". Is this a POD kit? No our system is not a
"POD kit". POD kits are put together "ad hock" using the stock needles and
no Cross-Over tube. The Predator Pro kit is a proven system that has been
Dyno and road tested to make sure all the components work together to
achieve optimum performance. Don't be fooled by imitations!!
The heart of our system are the Predator Pro Needles, our
Anti-Reversion Adapters, Cross-Over Max-Tube and our
Positive Crankcase Vent System. The Predator Pro needle was specifically
designed for the Predator system allowing for best performance, drivability
and gas mileage. The stock needle was designed for a stock bike to satisfy
EPA NOT for best performance when you eliminate the stock are system.
Our anti reversion adapters increase air velocity and reduce
reversion thereby increasing volumetric efficiency and power. There is
simply no comparison to
POD kits that use the stock needles and misc. parts.
Our kit has also been made turn-key and we provide proper technical
support. Our filters and adapters are designed to give the right flow and
to provide the best performance.
- How much of a
power increase can I expect with the Predator Pro? Please see the
side by side Dyno charts on our website done by RoadBike Magazine. With a
good aftermarket exhaust you should see a 20% increase over stock and often
times better depending on the exhaust used.
I have a Maxair Predator
purchased before 2006, is the Predator Pro a new version ?
Yes it is. The Predator Pro is the latest evolution of our legendary
Predator kit providing even better power and throttle response.
How is the Predator Pro different:
The major difference is our new proprietary Predator Pro needle. The
old style Predator used the stock needles which were designed to be used
with the stock air system. We custom designed the Predator Pro needles
especially for our air intake system, to offer better throttle response and
general performance. Our test-bed V Star 1100 gained 4 hp over the old style
Will the kit come with the exact size jets needed to be compatible with my
Yes, the is very
complete, with everything you need for ALL exhaust setups. Some major engine
mods. may require the Jet Bump Kit which gives you extra
jetting. If your bike does not have major engine mods you will be good to
go. If you have cams or HC pistons you may want to purchase the Predator Pro
Jet Bump Pak for an expanded range of jetting https://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Product_Code=JUC-1100PRO
Does the installation of the kit require any irreversible changes to the
existing parts, especially the carburetors? For example, to install
the new jets, does any drilling need to be done that would prevent a return
to the original equipment sometime in the future? :
No, the only
drilling that is done is to remove the plug the covers the idle mixture
screw so you may adjust them. This can easily be adjusted back to stock and
the plug is completely unnecessary.
Do the carburetors need to be re-jetted with your system and aftermarket
pipes are installed? : Yes,
you do re-jet and we give you everything you need for a stock engine (extra
jets can be purchased for bikes running aftermarket cams and/or High
Does the stock air filter cover remain on the V Star 1100 for aesthetic
purposes once your new Predator system has been installed?:
Its your choice. Our filters are hidden under the tank so you can leave the
stock doughnut cover in place for looks or you can remove it for a cleaner
I would like to know if there is any power increase if I use the stock
Yes you will see a
noticeable gain in power. Not as much as you would see with a full system
though.. We recommend a 2 into 1 exhaust for best performance. Slip-ons are
a reasonable low cost option that will give you a tremendous power increase
with the Predator Pro.
- Will installing the Predator kit have a negative
effect on my warranty:
No, This is a
myth sometimes perpetuated by certain dealerships. See:
Magnuson-Moss Warranty Act.
We have dealers that
install our air kits before the bike has even been sold to increase its
selling potential. Often times a customer will purchase a bike and the have
the dealer install our air kit and a set of pipes right off the showroom
Does your kit use K&N filters, what is their life span and how often do the
need to be cleaned: Yes, we use top of the line K&N filters that are
guaranteed for a million miles. We recommend cleaning your filters at your
8000 miles valve adjustment, when you have your tank off anyway. If a filter
should ever be damaged we will supply you a replacement, for a nominal cost.
It would be very rare and unlikely to damage one however. ONLY use
K&N Filter Recharger kits to clean and re-oil your filters.
have another air kit on my bike now. Can I leave this on for looks after
installing your product?: Yes you may and this is a great way to go.
"The Maxair for Go, the others for show!"
What are these Predator Maxmix Screws and why should I purchase them? The
are thumbscrews that eliminate the need for a screwdriver when making
adjustments to your idle mixture. We highly recommend these with the
Predator Pro for ease of tuning. Please see the tab above for more info on
ride in the rain quite often. Will rain be an issue with the Predator Pro?:
No, rain will not be a problem at all. We have never had a complaint
or issue due to rain with the thousands of bikes that this kit has been
installed on. We have ridden our own test bike daily through torrential
downpours with no problems at all.
What gas mileage can I expect with the Predator Pro : The average
is 42 to 48 mpg.
Are these filters large enough for this application? : Yes . These
are the size as the filters commonly used on the 1700cc Warrior. They
provide more CFM than you will ever need. Remember, a filter
too large can cause a decrease in overall performance and torque. Also our
filter s designed for optimal flow while preserving proper filtration and
together with our adapters reducing reversion for better torque in the lower
Can I install this myself? :
Yes, most certainly. If you can change your oil and can follow
instructions, you can do this in about 4 hrs. If any issues come up we are
available around the clock on our technical support forum to "hold your
hand" through the install process.
What tools will I need for this project. : You will need a basic set
of screwdrivers, sockets and wrenches. Also a clean work area. You will need
a way to adjust the float level which can be done with a metric caliper.
After the install you should synchronize your carburetors. You can purchase
SyncPRO CARBURETOR TUNER by Motion Pro
or you can make your own very cheaply with instructions found on our
technical support forum. Synchronizing your carburetors is a regular
maintenance item that should be done periodically on and bike with multiple
carburetors so this is a good tool for future use.
am concerned about adjusting my float level. Should I be and is this
Adjusting your float level is a very simple job. We have full
color instructions on our technical support forum on how to do this simple
procedure. We have gone to great lengths to make this a very simple task. As
a result t is the easiest part of the install process and should not take
more than 10 minutes. We also have a video on our tech support forum to
bike has already been re-jetted with another kit. Will I need to re-jet
again? Yes, you need to re-jet using the jets we provide
to accommodate the Maxair Predator Pro needle and the huge increase in air
flow and power.
Can my local dealer install this for me.
Anyone who can read and follow instructions can install the Predator Pro

Outstanding increase in performance, 5.18.2021
Customer: Randy R (Schertx, TX)
Upgraded the exhaust a few years back and I thought the small upgrade in performance was sufficient. Decided to upgrade the intake/carbs with the Predator Pro kit and WOW. Adjusted valves, installed the kit, synced carbs and when I took the bike out for a country ride it felt like a totally different and powerful machine.
Instructions are very helpful and easy to follow.
Un fu*king believable , 5.17.2020
Customer: Steven B (Los Banos, CA)
I've tinkered with, modified, and rode bikes my whole life. I'm now 72 and still going strong! However, for a small amount of money this is the most bang for the buck I've ever got and without major tear down!
Amazing upgrade - great value!, 10.4.2019
Customer: Kenton (Kimberley, BC)
This is probably the most dramatic increase in performance I have ever encountered for a motorbike (dollar for dollar). It really turns the tame little 1100 into bit of a rocket-ship. On top of that the bike starts better and achieves better fuel economy.
I made a mistake during installation and Max took the time to call me personally and explain how to work through the problem.
I can wholeheartedly recommend this - make sure you get the CSR and Maxmix screws to go with the predator kit. It is really a complete package.
Predator Pro, 5.4.2019
Customer: Anthony Crochet (Hobbs, NM)
I've always wanted a bike to keep up with the big guys. Just couldn't seem to do it with my 09 Vstar 1100 until Maxair. I wanted more power and economy so I did the normal things, big air intake, exhaust just wasn't quite enough. Being skeptical as most of us are, wasn't sure about Maxair. So after reading reviews and testimonial I bought it. Now I have to wait on the big guys. Every thing said about it is true. Take your little pudder and make it a screaming beast and that's no joke. When I twist the throttle off by the time I reach 5 gear I'm at 80 . And that's with out the rev-limit shut off. Plus from 35-37 mpg to 42-45 mpg . Which is unheard of with carbs. Do your 1100 a favor and bring it to its fullest potential get Maxair. P.S. the thumb screws are worth the $$ !! Thanks Max !
Great product, 4.20.2019
