Q. Are Toomey Racing USA's T5's the "Best" pipes for the Banshee?
-
A. Yes.
-
The more complete answer is that our pipe makes more power, over a wider range than any other pipe available. We do this by providing to the customer not only a better and more thoroughly researched design, but a complete kit as well. Everything you need to install and properly tune your machine for racing is included. No other manufacturer gives you all this.

Q. Why are the T5 pipes the best?
-
A. T5 pipes the best!
-
Because we have tested all the other makes we can find,
on our own computerized dyno facility and have assured it. We have been involved with this basic Yamaha engine design for over 25 years. In one form or another, R5, RD-350, RD-400, TZ 250, TZ 350, TZ 700, TZ 750, or Banshee, this engine is basically the same 64X54 Bore & Stroke engine Yamaha has been producing for years.
-
We have been involved in the road race version of these engines since the '70's. In 1979, in the TZ 750 version, we won the Daytona 200 Road Race using a very similar pipe to what Banshee riders use today. We made several changes to allow it to run at lower R'sPM than the TZ 750, thus gaining a lot of "low end" power.

Q. What is included in the Pipe Kits?
-
A. Pipe Kits with Extras!
-
The pipe kits include the Pipe bodies, Stinger tubes, Aluminum Silencers and Rubber Mounts. In addition, and unlike many other manufacturers, we also have done the carburetion testing and have developed the perfect jetting kit so all you have to do is install the parts in accordance with the instructions and the carburetion will be perfect as well as produce the maximum power available. No having to guess. We also include the finest air filter in the business, the Uni-Filter two stage foam filter, 12 Uni-Airbox vents, and a free spray can of filter oil. You will find 8 pages of simple installation instructions too.

-
Q. Are the Pipe Kits hard to install?
-
A. Not really!
- If you are accustomed to working on your bike, there will be no problem. It is a really good way to become familiar with your bike too! If you are not the mechanically inclined type, we would suggest the enlistment of some of your smarter friends, or your friendly Yamaha Dealer. Total time for the install, about 2 hrs. (One and a half hours if you bought the 2:1 Air Filter system kit.)

-
Q. What kind of Two-Stroke Oil shall I use? At what mix ratio?
-
A. Our Recommendation!
- We recommend using Yamaha's YAMALUBE "R" mixed at 32:1 (actually anywhere from 28:1 to 32:1 is fine) This oil has proven itself for years in roadracing, and we use it on the dyno where there are higher loads imposed over longer periods of time than anywhere in the outside world.

-
Q. What about Spark Arrestors?
-
A. We use the "Sparky" type arrestors.
-
We don't particularly like the mounting arrangement, or the looks, but these units are the only ones we could find that are U.S. Forestry Service Approved, and don't hurt the power. All others we tested hurt the power quite a bit. After all, that is why you are interested in our pipes, because you want the most power! We are seeking approval for our "Hush Kit" as well, so stay tuned.
top
-
Q. What about the Noise sensitive areas?
-
A. "Hush Kit!"
-
We have developed a supplemental silencer system called the "Hush Kit".
It installs on the back of our regular racing silencers, so there are no wasted
parts when you buy a pipe kit. We have recently been tested by the Oregon Dunes
Sound Check personnel, (7/30/98) using their equipment, at 87dBA using this setup,
a 12 dB reduction!
It was designed to comply with noise regulations at Oregon, and Michigan riding
areas, now and well into the future.
We have settled on this design because it is the only design that does not hurt
power. All other systems we tried hurt power a lot, like some of the big silencers
available from other companies.
We have since heard that there are even more stringent noise regulations being
enacted. If that is the case, we all lose more riding areas. We must do what we can
in the face of ever increasing government regulations to beat them. Until we
unelect some of the worst destroyers of our liberties, we will continue to lose
riding areas. Do what you can peacefully.
It is a clear attempt by worthless, puny government regulators, seeking to exercise
their power over us, securing their own tax consuming jobs and thus feel worthy of
our forcefully extorted tax money. It is a sick system, which only serves to hurt
the ATV (and the country's)economy while producing NO useful benefit.
Unfortunately, this is the way most things are going these days, unless we stop it.

Q. My Pipes don't fit quite right, What's wrong?
-
A. Read This Carefully!
-
All T5 pipes are made from the same jigs. 99% fit with NO problems. It is virtually impossible for two pipes to fit differently. The variation seems to be in the frame and engine positioning in the frame. I know this sounds like a blow off, but it has a basis in fact. The engine is rubber mounted, plus it has a lot of slop in the mounts. We have seen as much as one inch difference in motor positions in the frames. With this in mind, we designed the mounting of the pipes, also totally suspended in rubber so they never crack, to accommodate these variations.
The trick seems to be to install the pipe set completely (L&R) from head pipe to silencer while keeping all attachment bolts loose. Then, push or pull everything into alignment together so that both left and right pipes fit equally THEN tighten up all the bolts (as much as is possible, because they do fit differently -- The motor is offset in the frame to the left about an inch or more). In the unlikely event that there is still some error in the fit, a little judicious tweeking of the pipes, stingers or mounts may be in order. The pipes will bend ever so much with no damage at all (chrome ones may flake chrome where bent if it is a lot). This is not a bad thing, it is a reality of pipe fitting. It is impossible to fit these pipes as tight to the chassis as you want while accomodating all the variations.
If you still have problems, please call us Tel: 805-239-8870 Fax: 805-239-2514 and we will do everything we can to help you insure a proper fit. It may require you to return the pipes to us so that we may jig test them, and or bike fit them by hand. It doesn't happen very often (maybe 3 or 4 times a year) but it does happen. Just don't freak out, we will do whatever is necessary to help you.

-
Q. How often do I need to repack the silencers?
-
A. Our Recommendation!
-
It depends on how many hours of operation between rebuilds. We recommend repacking every 10 hrs., or as needed for professional racing. For casual dune playing, I should think every two or three months should be ok. You need to remove the snap ring and visually inspect the glass to arrive at your own maintenance schedule.

-
Q. Why are the pipe kits so expensive?
-
A. "You get what you pay for."
-
That's the best explanation. "Expensive as compared to what?" we might ask. Other brands? Well, you are not receiving near the same quality or service with those other brands. With your purchase from us, you also receive:
-
Unlimited technical assistance (phone)
Access to our website for time sensitive exclusive information
eMail notification of new products and upgrades
Special upgrade pricing
Lifetime performance guarantee.
Lifetime quality guarantee.
-
These things are simply not available from other companies. If your pipes ever fail, crack or otherwise don't perform as new, we will at our discretion repair or replace them free of charge. All you pay is the freight.

-
Q. Why doesn't Toomey Racing Port Cylinders?
-
A. For a very good reason!
-
We simply don't have the manpower or time. That's not to say we won't ever, we have done it in the past with much success. We very well might in the future, but right now we are kept very busy shipping the enormous quantities of Banshee pipe kits we sell today. We won't branch out into new areas without insuring the quality of that work, will meet our standards. We now have so many projects and private contracts in the works that we simply cannot meet the demand at the quality level upon which you insist.

-
Q. Why does the Banshee overheat?
-
A. It is very common for the Banshee to overheat in hot climates.
-
The problem is insufficient radiator area and ducting. It is imperative that you follow a few simple rules to minimize the problems:
Maintain the radiator in good condition, keeping it very clean and fins
straight for good air flow.
Use a coolant additive like Prestone Anti-Freeze, instead of only
water.
Use ONLY distilled water. Using regular tap (mineral) water will clog
up the interior small water passages.
Try to seal the sides and top of the radiator so air will be forced
THROUGH not around the radiator.
Most importantly, NEVER come to a stop, and sit and chat with your
friends for any length of time and then ride away under power. Remember, the
radiator is the only thing that dissipates the heat from the engine, and the
air flowing through the radiator is the only means of carrying off the
heat, so when you come to a stop, there is NO cooling action occurring. If
you need to stop for a couple of minutes, turn the machine off.

Q. What are the benefits / downside of chrome plating?
-
A. Chrome Plating helps your pipes look great!
-
Chrome Plating has a high resistance to corrosion and improves the overall looks of your machine. Although not a perfect solution, it can turn yellow or blue with heat. If your engine is running properly with our pipes, the headpipes will turn blue after long periods of sustained full throttle operation, it is a purely a function of temperature. Chrome lasts longer and stays looking better than most other choices, but will add about $120.00 to the price of a pipe kit. Chrome can peel over time because the steel to which it adheres has a different expansion rate when heated, and cracks can appear and later lead to flaking.
Nickel is almost as expensive, looks yellow, and is soft, allowing scratches. Some companies "Flash Nickel" their pipes for very little money or even free as there is no polishing performed. They call it "Gold Series" or something to that effect. It doesn't look very good though, it doesn't have the deep polish and lustre of our chromed pipes.
Paint needs maintenance, isn't very strong and burns off but is the cheapest.
Therefore warranties regarding chrome last only as long as it takes for the pipes to arrive at your door. If it arrives damaged, we will send it back to plating and they can strip it once, and re-plate it (it takes about 2 weeks), we would probably just ship you a new one so you don't have to wait. It is hard for us to deal with chrome, as it is something we must have done outside of our shop, and therefore have little control of its quality. We pick our chrome vendors carefully and insure they have the same commitment to quality as ourselves. So far, so good. The chrome looks really good.

Q. Why is there a "Rich Spot" from 4000 to 5000 RPM, and how do I get rid of it?
- A.
- There is a "rich spot" between 4000 and 5000 rpm on the Banshee..... While
it is true that it IS rich, the REASON it is rich needs more explaining.
The is an anomaly in the intake tract of the Banshee. What we think we have
discovered is, because there is a sonic wave at work in any confined space,
(like the exhaust pipe or intake tubes) this wave must be timed to help you
with that which you are trying to accomplish, as with the exhaust pipe.
There will be some rpm range where the wave will be most out of phase, and
an area where it will be most in phase, hopefully we can arrange the
in-phase part while the pipe is having its in-phase part....! That is why
you feel the big burst of power when the pipe kicks in, because these waves
are working in harmony.
On the Banshee the most out-of-phase area is right before it synchronizes
with the pipe.... so 4000 to 5000 rpm, then at 6000 it starts harmonizing
it's pumping action and you feel the pull in the handlebars!
What is happening actually is that this wave is being reflected back and
forth inside the intake tube (tract) regardless of the fact that the air is
only moving in one direction, the wave, which has little if any mass, can
travel in both directions and does... Each time it does, it passes the
needle jet and when it does, it pulls fuel. When this happens there might be
a piston stroke with several helpings of fuel instead of just one, therefore
it is rich.
The intake tract is too short, and this is one reason why it is a bad idea
to put the little K&N filters on the back of each carb, effectively
shortening the intake tract even more.
It is also a GOOD reason to use our 2:1 filter system because we add about 3
or more inches to the length of the intake tract, helping to lengthen the
time it takes for this wave to propagate from one end to the other, and to
keep the resultant mixture confined so it may be used and not spit back into
a filter....
Because this is an RPM specific phenomena, it cannot be "jetted out" because
conditions change in response to RPM, not throttle position. If it was at a
particular throttle setting, then we could easily say, that at this setting,
certain circuits are active and make adjustments accordingly, but it is not.
Raise the rpm a little and it goes away. This is one of the reasons Yamaha
chose to put the "cross-over" tube between the intake manifolds. This makes
one intake tube think it is larger than it really is (as far as sound
propagation goes) therefore lowering the frequency of the sound wave,
dampening the effects. You can try this experiment yourself, just remove the
crossover tube and be sure to plug up the holes in the intake manifolds from
which the tube came, then ride it. You will see the difference!
This is also where the "Boost Bottle" argument comes in....
Yes, there must be the cross-over tube, but the engine couldn't care less
how big it is.... this tube is used to communicate the volume information
from side to side, not to magically "store-and-forward" mixture for later
use, as some have alleged. Nor is it able (as far as we can detect) to allow
mixture to be drawn from both carbs at once..... So the "Boost Bottle" as a
performance product is a complete placebo and only serves the manufacturer's
pocket, not the customer's needs. Beware of companies who sell this kind of
thing, they are not being true.
Remember, if it sounds too good to be true, it probably is....
