Equipment Test: Having
a Blast with the Toomey B1 Kit
Good Quads Never Die

Who knew that buying a Yamaha Blaster was
like joining some secret society like something
out of the Da Vinci Code? I certainly
didn’t realize it until after picking up a 1995
model and the tips, suggestions, and performance
enhancing advisors began coming out of the
woodwork. Although Yamaha discontinued the
model in 2006 due to ever increasing strictness
of EPA regulations, the quad is far from dead in
the eyes of legions of Blaster holdouts lurking
Enter the Blaster B-1 kit from Toomey Racing
USA. If ever there was a single product everyone
insisted that I sample, this was the one.
I was reluctant at first, having delved into the
pipe game in the past only to encounter jetting
snags; but the B1 kit was different or so I was
told time and again. Toomey takes the
guess work out of installing their hand-made
pipe and silencer by including everything the
tuner would need in a single package.
Intrigued, I figured perhaps this was the exact
type of product an impatient mechanic (and I use
the term loosely) such as myself had been
After carefully studying their site, (www.toomey.com)
I placed my order, and in a week a massive box
showed up on my doorstep. Inside was
indeed everything I would need to get the job
done. Aside from the beautiful chrome expansion
chamber, pipe, and silencer, Toomey includes an
air filter, head flange, the proper carburetor
main jet, 12 air box vents, new springs and
hardware, and full mounting instructions (they
even throw in a decal kit that would easily set
you back $15 on eBay).
The attention to detail that Toomey emphasizes
in their products is immediate the moment you
open the box. The show-quality chrome pipe
simply oozes with quality from its perfect hand
welds to its heavy-duty mounting tabs.
I’ll admit that I was already pretty convinced
that the B1 kit was a stellar investment; little
did I know the best was yet to come.
50% weight reduction. The B1 weighs 6
pounds, the stocker 12. Ours weighed
even more when you factor in the rust.
Installing the kit is an afternoon affair for a
fairly adept backyard tuner. Thankfully,
Toomey includes some pretty thorough
instructions. The hardest challenge of
this ordeal, in my case, proved to be in getting
the 12 year-old stock system off. Time and
moisture apparently haven’t been very good to
the stock steel pipe, as mine was pretty well
bonded to both the head and the silencer.
Once free though, the rest of the process was as
simple as following the steps. Here is
where Toomey’s attention to detail is simply
priceless! The mounting tabs for these
pipes line up to the frame as well as, if not
better than OEM specifications. This is
without a doubt the best fitting full exhaust
system on the market.
Once the pipe and silencer are bolted on, I
turned my attention to the carburetor. The
kit includes a #310 Main jet and very thorough
settings to get you going. The directions
involve changing the needle clip position and
provide confirmation of every single carburetor
setting. They weren’t kidding when they
said the B1 kit takes the guess work out of the
installation. Next, the kit advises
drilling 12 holes into the air box lid into
which the included foam-lined vents are
inserted. For those fearful of drilling
out the unit, the system also allows for running
the Blaster without the lid at all (which is the
option I opted for). Finally, I oiled the
air filter included in the kit and attached it
into the air box. Total time of the
installation was about three hours (much of
which resulted from having to pry the old system
Once attached, the B1 pipe looks like a
million bucks. Sounds like it too.
This simple modification improves the appearance
of the Blaster tenfold! In fact, the B1
pipe is so attractive that we soon began to
regret Yamaha’s concealing pipe routing.
This is a system that absolutely gleams.
Not to mention the pipe’s mounting and routing
is so precise that there are no rattles, and no
frame, or plastic contact.
Stepping on the kick starter only confirms what
the beautiful chrome system hints at while the
machine is standing perfectly still: The little
195cc air-cooled mill has a lot of untapped
potential in stock trim. The exhaust note
is much barkier without being obnoxious.
For those who have yet to experience that
(should be) patented Toomey sound, I can only
describe it as crisp and snappy from idle to
however high your rev-limiter allows.
Blipping the throttle only further causes rider
salivation like one of Pavlov’s dog experiments.
The entire machine sounded different. It sounded
Taking it Out:
After allowing the machine an opportunity to
warm up, I slowly fathered the clutch, not
exactly sure what to expect. To my
delight, the Toomey system does not hamper the
usable low-end grunt of the Blaster whatsoever.
A lot of systems focus on over-rev at the cost
of low-end ability but not this one. The
Blaster still inches forward at the moment of
engagement only now the middle of each gear
feels much more defined. The power
progression is very linear, building literally
from idle on up. The biggest surprise came
once I powered out of the middle-range and into
the upper reaches of the power band. No
longer does the little Blaster fall flat up top!
As any Blaster rider can attest, the quad
requires a very strange riding style because of
its lack of grunt up top. In stock trim
the only way to make the Blaster go is to ride
the wheels off the middle of each gear then to
shift quickly before the power drops off.
One learns quickly to short-shift the Yamaha if
they want to hang with the pack.
The Toomey system turns the choked-up Yamaha
into an entirely different animal in this
regard. The quad absolutely barks up top, with a
hit we typically associate with a full-on MXer.
The power of the B1 kit is not only stronger
across the board; it is quite useable as well.
While there is no doubt that it delivers on its
promise of increasing the horsepower by 25%,
what impressed me most was that the increased
power can be transferred to the ground very
effectively. Rather than abundant noise
and wheel spin, the B1-equipped Blaster launches
out of the hole like a rocket and continues to
make epic stride until you’re good and ready to
click it up a gear. Then the process
repeats itself until you find yourself ripping
to the top of 6th.
There are no dead spots along the way, and
somehow Toomey manages to open the Blaster up
without giving up any of the traits that make
the stock grunt so desirable.
Included is literally everything you
need to take your Blaster from zero to
All of the hype and hoopla preceding my time
with the B1 could not have prepared me for how
impressive this system really is. The fit
and finish are in a class of their own.
It’s hard to convey the confidence that comes
with knowing everything you’ll need to do the
job right is included in the kit, and the
detailed installation instructions are there to
alleviate what little doubt that might remain.
At the end of the day, this is without question
the most power-enhancing modification that can
be performed to the machine this side of full
engine reworking (and even then) . . . Toomey
proudly claims that the B1 Racing Kit is the
result of countless hours of research and
development; and after using the product first
hand, we believe them! As convincing as
their dyno chart appears when comparing the B1
system to the FMF and Pro Circuit pipes, the
graph fails to accurately portray how impressive
the delivery of the increased power really is.
Toomey manages to improve the power output
across every single point of the spread whether
you race motocross, XC, woods, trail, or play
About the only negative to the entire affair is
that Yamaha’s routing doesn’t allow for full
view of the B1. A pipe this beautiful should be
on display for all to see. Rest assured though,
what the fenders cover will be more than made up
for in both the factory tuned sound and
performance this setup brings to the table.
Bottom line: $349 for the entire B1 Racing
package is “chump change” when compared to the
cost of the current 4-stroke pipes (which
average $500 just for the exhaust). If you own a
Blaster, plan to own one, or just know someone
