Pictured above is our FXR Turbo Orca swingarm with 1" higher shock mounts. It has 2" of adjustment for the chain drive and uses a 25mm late model axle for a 17" Dyna rear wheel. The 2008 Swingarm has been modified to use our 5/8" 1999 FXR CVO2 transmission pivot shaft. A late model 4 piston CVO Dresser caliper provides the rear stopping power.
We are using a 1998 Dresser oil bag 5 speed transmission with Jims Fat5 gears. We also added a secondary gas tank where the original oil bag went.
We raised the shock mounts 1" to use with 13" shocks (same as running a 14" Shock) to get 6.25" of lower frame ground clearance with the smaller diameter 150 x 60-17 rear tire. We are also using stock narrowglide 39mm fork tubes with a 17" Buell front wheel (110/70ZR17) with the original 3/4"axle. We get an improved swingarm downward angle of 4 degrees as an additional benefit.
Sitting on its wheels the bike has 29 degrees of rake.
00-1306 M-8 Nitro Pro Stock Challenge
We make a 00-1306 Pro Stock Challenge LSR 2-1 "Nitro"
exhaust with a "Kick" to keep the exhaust off of the M-8 Dressers
saddle bag. All the new M-8 models have better cornering clearance and
we tucked this "Nitro" Challenge design up where it cannot drag and
made it exhaust away from the right side bag.
Full race. Available with 12mm and, if specified, two additional 18mm
oxygen sensor bosses (no charge). Standard is two 12mm bosses for the
OEM 12mm sensors.
Here is our
56mm throttle body for our RSR EFI Turbo set up. It is configured with
two (2) 650cc Bosch EV6 (12 Ohm) Injectors in a 2 Bar (15 PSI Boost)
system destined for an 80" EVO motor that we pre-programmed for 195hp
We are phasing out our RSR Fuel Injection systems after 28 years. After
existing RSR EFI Turbo orders are satisfied and will be transitioning
to Bosch Motorsports 60mm Fly-By-Wire electronic throttle bodies and
Cosworth Pectel SQ6 and SQ6M electronics for our Turbo Evo ORCA Motors.
Our Intercooled Turbo Kits for oem Harley Twin Cam Delphi systems
remain unchanged . Take a look at the above. We did not show all
the parts...take a guess how much time is tied up in this stuff.
All of this
is made from, as they say, "scratch"...Lots of records, lots of
miles...lots of stories. 28 years ago there were no closed loop
turbos...except at RB Racing. 200 mph Harleys, BMWs, Suzukis, Triumphs,
Kawasakis....way before anyone else. Things do not sit still. Time to
move on. Life gets even more complicated and more expensive.

Indian Owners Happy with New LSR 2-1 Pro Stock Spyder Systems...111 / 116"
Customer writes: "Here is a
pic of my 2017 Indian Chieftain Elite with the RB racing pipe. This
bike has the 116 kit and is a blast to ride. In 25 years racing drag
bikes, this is by far the best sounding bike I’ve owned. Love the pipe!! Thank you RB
racing ..... Don". 00-1400 on a 116".
Customer writes: " Please find attached a picture of my bike with your Exhaust system as promised. I absolutely love the new Exhaust. I used to have the Freedom/Rinehart true dual exhaust and I liked it very much but the RB Racing LSR 2-1 is just so much better when it comes to the performance and the sound.
Thanks again for your
service and support, I appreciate it very much.
p.s. I have the 116" Indian kit, Vic Baggers VP60 intake and the Dyno Jet PVCX with a custom map.
On the Dyno, it puts out around 112HP and 134 Torque. Iwan". 00-1399 on a 116".
Note: We spent about 3-4
months doing and redoing these until we were happy with them. Then,
once you start shipping the first group of parts, you never know what
may come up. We made a few more changes based on customer feedback and
the systems seem to be well received. All this takes time. The goal was to
build a full race system with sound attenuation and to focus on torque, and a reduction
in weight and heat.

Machined Shovelhead Flanges
To insure correct port
sealing and geometry we machine the Shovelhead port spigot to 1.745" to
insure roundness and then TIG weld the flanges to the primary tubes.
We've been making Shovelhead exhausts for over 40 years for FX and FL
models in baffled LSR 2-1 Turn Out and Slash Cut and full race LSR 2-1
Pro Stock versions.
We build to order because
we have hundreds of part numbers in three different finishes and a
myriad of options dating back 40+ years to Shovelheads. Follow the link
to see what exhausts we have ready to ship, either from cancellations,
extras we made, or various reasons...Often it's an item when we simply
make a second one when it's something we do not do often like V-Rods.
Coat Black Ceramic
The Dual Coat Black Ceramic
is shown here after we media blast the top Black Ceramic Coat off with
#100 Oxide leaving the base Silver Ceramic Coat exposed. Holding the
blast gun at one spot for a longer period exposes the bare metal
The Dual Coating process is expensive and takes several days with three trips to the oven. Once to clean the exhaust, once to bake on the Silver Ceramic at 600 Deg F and a third time to bake on the Black Ceramic Finish at 600 Deg F. It's the only way a Black Ceramic Finish will hold up to chemicals and corrosion. We have years of experience with this process.
Serialization of Your RB Racing LSR 2-1 Order.
We use 2000 Degree F
Ceramic coatings on our heat shield hose clamps for our Dual Coat Black
LSR 2-1 exhaust systems. It makes the clamps "disappear" and they will
We also heli-braze metal tabs
inside our heat shields that are stamped for the part
number and your order number. The three digit number is the part
number...All LSR 2-1 exhausts are 00-1XXX, with the last three digits
indicating the part number. The alphanumeric four digit number is your
order number. The exhaust, as well as the the heat shields, also has
all seven digits stamped into it. The "blank" tab is a spacer only and
does not use a hose clamp.
165HP @ 9 PSI Boost; 200HP @ 13 PSI Boost... 95 Cubic Inches
Torque is the game..Take it
to 4 or five psi of boost, short shift, and do it again...80 mph
instantly. Or, if the handlebar adjustable boost control knob is set at
9 PSI, get 165 hp now. 13 PSI 200 hp. Turbo goes to 25 PSI. Torque allows you to effortlessly roll-on and
pass that line of Semis, or leave the other bikes behind. RB Racing Turbos.
The Indian Chief is a "from the ground
up" interpretation of the classical V-Twin, kept alive for over 100
years by Harley-Davidson, the sole survivor. In 111 or 116 cubic inch
formats it's short on horsepower and long on clean sheet engineering.
Indians are here to stay this time around after several aborted
attempts to revive the marque.
Beautiful paint and chrome and true
"Indian Heritage" styling it's a more modern interpretation of the
classical V-Twin...This time around with three camshafts and some pushrods as straight
as an Indian's arrow .
The OEM exhaust has little in the way of
performance tuning. We've got that covered with a pure merge collector
LSR 2-1 design. Maximum benefit with Stage 1/2/3 and larger throttle body (60mm) modifications past 130 horsepower.
Bosch Motorsport Ignition Coils
These are the Bosch Motorsport Ignition
Coils that we use in our dual-plugged Turbo ORCA motors. We stock these
along with the specialzed connectors. ORCA motors use two 12mm
racing spark plugs per cylinder for bore sizes 4.000" to 4.375". We
trigger these with a Cosworth Pectel SQ6M ECU, programming four
separate spark maps, each with 25 x 25 sites, for a total of 2500
ignition points. In terms of keystrokes to enter this data...a bit shy
of 12,500 keystrokes. No one said this was going to be easy. We use
Champion 662 / A59C resistor racing spark plugs, which we also stock.
New RSR Wideband (Bosch LSU4.2/9) AFR Gauges
RSR Dual Air Fuel Gauges for the 18mm
LSU Wideband Sensors (20:1 to 10:1 AFR) are in production. IP67
billet enclosures these have our 10 L.E.D. interface that tells you at
a glance if your AFR is Stoichiometry (14.56:1) or peak power ratios of
13.5:1 or 12.5:1...and ratios of 11.5:1 or richer.
You cannot divert your attention to watch a digital gauge and try to read, or remember, spooling numbers. You need hysterisis at a target ratio that can be interpreted at a glance whether you are dodging cars, or going 200 mph. We just provide the AFR Gauge, not the Bosch Lambda sensors.
The white arrow indicates maximum torque and power. Easy to see at a glance at full throttle.
Left to right 10 L.E.Ds going from lean to rich: Five Green lights, Two Yellow lights, Two Orange lights and one Red light. These display the range 20.5:1 to 11.5:1The two Yellow lights L-R are 15.5:1 and 14.5:1 (Stoichiometry)

Real World Tuning Package...While you ride..Not on the Dyno
When you order a complete LSR 2-1 exhaust
with the RSR Dual Air Fuel Ratio Gauge and
The TTS MasterTune there is a $75.00 discount on the total price.
You can observe while you ride in the real world to evaluate
transitionals and wide open throttle. The RSR Dual Air Fuel Ratio Gauge
is waterproof and Harley-proof. It gives instantaneous visual
information that is available at a quick glance...No numbers, just
position and color reference (GGGYYYOORR), to tell you if your mixture
is correct. Invaluable for wide-open runs through the gears or
evaluating transitionals on your roll-ons.
The above chart gives the response times
of the 2009 and later 12mm Delphi Oxygen sensors. In actual dyno tuning
have to hold one "site", i.e. the intersect of load and rpm to get an
accurate feedback as the sensors are always "behind" due to their
response times. That's why you see Superflow engine dynos doing step
testing so things can stabilize. In a tenth of a second you could be at
any location on the fuel map...Not to mention the eight surrounding
sites that are being interpolated.
The problem with "holding things" on and eddy current dyno is that is things heat up in these air
cooled engines and the hidden code in the Delphi ecm starts changing
things. You can really only do one wide-open throtte pull on a dyno at one rpm
and load site before the engine heats up too much.
Best do real world data
recording with the TTS while you ride and then evaluate, in real time,
your map with the RSR milli-second fast RSR Fuel Ratio Gauge with
genuine 18mm Bosch O-Sensors. Real
time monitoring when you ride is the only way you can evaluate
transitionals, acceleration additives, and wide open throttle...all in
the real world moving through the air and on the road like you do
normally. All LSR 2-1 exhausts can be ordered with both 12mm and 18 mm
O2 sensor bungs.
People kept asking about RB Racing releasing LSR 2-1 exhaust systems for the new Harley Motor. Well, we are fixtured for them with a new muffler design that takes into account the increased compression and displacement, but were not releasing anything until some things settled down. No matter what people say, this is an emissions-designed engine with a lot of compression, locked in place valve adjustment and camshafts that are simply going to give you next to zero in gains for your hard earned money in just changing the exhaust. Every exhaust manufacturer wants your $$$ before things are settled down. We don't. We'll released them when there were real gains to be made.
Testing has shown cam changes need to be
made along with a 2-1 exhaust to make any appreciable gains. Go ahead
buy your $500.00 air cleaners and your $700.00 Monster Slip-Ons...keep
the economy going. Dealer level cam modifications with CNC ported heads
are showing about 130 hp...about where the TC 120R motors were.
