Dual 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
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.
We maintain a database on
all exhausts sold so we know when the exhaust was sold, who ordered it,
and any and all details concerning the order.
Turbo System with RSR EFI
One of the last of our
RSR Closed Loop EFi Systems we will be shipping. We started this closed
loop efi intercooled turbo stuff back in 1989 and set all sorts of
speed records and won drag racing championships..All pretty much on our
predictive programming with very little input from the customers. Our
RSR EFi systems went on bikes that were carbureted or scratch built
race bikes. We were way,way, ahead of the curve.
Packed into two heavy duty boxes with laptop compter and all hardware for overseas shipment ...90 lbs.
The last 4 years we have been testing and racing with high-end Cosworth Pectel SQ6M
electronics at Bonneville. These systems have a very steep
learning curve with over 8800 programmable functions and tens of
thousands of entries. Since few of our customers understood our EFi,
which was dead simple, even when we wrote the programs for them, going
to a more sophisticated system will be interesting. These will only be
going on scratch built bikes with Single Cam EVO Orca motors or 32-2 Crank Triggered motors with no
OEM electronics. Complete control of all functions in one black box.
We have turbo systems for the OEM EFi Harleys 1999 to present.

These new Softail models have different exhausts than do the M-8
Dressers and have no relation to the EVO or Twin Cam Softails. M-8
Engines are taller, the ports further apart, and whereas the M-8
Dressers are rubber mounted, the new Softails are not. We have
specialized exhausts for all the M-8 Softail models including newest
the M-8 Sport Glide (bags).
The above pipe is for a M-8 Dresser. The
pipe is made in three pieces with two slip joints (no clamps!) for the
rubber-mounted Dressers. Dressers use a three point transmission
mount. On the LSR 2-1 Black Holes and LSR 2-1 Pro Stock Spyder Systems
there is an additional rear bag mount.
The M-8 Softails (all nine models) are two piece systems as the engines are rigid mounted.

New Indian Chief LSR 2-1 Pro Stock Exhausts
New Indian Chief LSR 2-1 Pro Stock Exhaust Systems.
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.

We met Diana late on (2015) in our 12 year long funding and providing all
technical assistance to a Bonneville Land Speed Racing Racing Project.
Diana was promoting the racing effort, organizing Benefits for the race
team and shutting down her business to go to the Salt Flats. As the
race bike was 900 miles away from Los Angeles where we are, we wondered
who the hell this "Diana" was that Bryan Stock, the 200 mph record
holding driver, said was kicking his ass.
Well, people are complicated and often they have agendas so we tend to
keep our distance and keep things simple. Hard lessons learned in over 40 years of this
shit. Diana fit right in with a bunch of bikers and the Bonneville
both two and four wheeled, met Burt Munro's son John, was
getting rides around the salt in Rat Rods with people she just met,
fought to get us hotel rooms, and shot some amazing photography. No agenda, just a good heart.
Our involvement in the race project ended post 2017 Speedweek.
Diana owns Grizzly Dairy Wear & Supply
supplying products to the USA Dairy Industry and photography is her love.
Hitting the road in her F150 she documents the beauty she finds
out Diana's Photography on Facebook
and her Smugmug
page... Bikers, Harleys, C&W and Hard Rock Bands, Nature, Horses, Old
, The Homeless, Architecture...whatever catches her eye.
Diana's photography graces International
book covers and National magazine covers as well as Idaho travel
magazines and Internet sites. You have to have empathy to capture the
soul of the subject. When Diana hits the road she documents what we can
see if we only pause and open our eyes and hearts
We have her photography on various pages of our website...some things we never saw when they were staring us right in the face.
Diana's latest YouTube video.
Customers purchased some items from us to help finance Diana's trip
to 2018 Sturgis Bike Week. Diana (Center above) will be armed to the
teeth with her Canon Camera gear documenting the bike and music
scene..and maybe your bike. Thanks for helping make her trip to Sturgis Bike Week possible. Payback.
August 2018: Diana made it to Sturgis, saw Kid Rock, thousands of
bikers, took an untold number of photographs of people, places, and
documented things you would never have noticed. As we say she "Got out
of Dodge" for a week to mix it up with the world.
Follow Diana's 2018 Sturgis photography on her Facebook
pages as she processes and posts the photos. If you
show up in the pictures buy a print from her or, even if you didn't,
do the same. You might not have made it to Sturgis but you can see it through someone else's perspective.
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 11.5:1
The two Yellow lights L-R are 15.5:1 and 14.5:1 (Stoichiometry)
The two Orange lights L-R are 13.5:1 and 12.5:1 (Maximum torque and power)
The Red light is 11.5:1

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.
It's still an air-cooled 45 degree V-Twin
no matter what they say about water or oil cooling. BTUs are BTUs...It
just has less flexibility in terms of modification than
EVOs or Twin Cams at this time. Another expensive puzzle. Does have more torque than before with the compression.
People tend to forget these are heavy couches. Adding weight is a
no-no. One of our M-8 test bikes came in with a V&H Duals that,
we removed them, weighed 41 pounds!!
Our M-8 exhaust weights far less than Half of that and the Pro Stocks
1/3 of that. Power to weight ratio. Heavy couches.
The Milwaukee-8 is a taller, heavier
engine with the O2 sensors moved upstream, closer to where they should
have been. Earlier LSR 2-1 designs will not fit this motor. We supply a
different saddlebag mount system for our under the bag designs like the
Pro Stock Spyder and Black Hole. All systems also have a three point
laser-cut mount off of the transmission.

for a customer who wanted a "Really loud racing exhaust". At the dealer
level cnc ported heads, cams and bigger bore kits are up to about 130
hp. When you consider an 80" EVO was about 58 HP with 175 to 200F oil
temperatures it's no wonder these run closing in on 300F hot.
Milwaukee 8 Exhausts: 12mm and 18mm O2 Sensor Ports Standard
All LSR 2-1 Milwaukee 8
Exhausts come standard with both 12mm and 18mm O2 ports. This gives
customers the choice to run either the OEM 12mm or 18mm O2 ports (or
both with our RSR Air Dual Fuel Ratio Gauges) and tune with various
narrowband or wideband options on the market. Screamin' Eagle Smart

fabrication and machining in these. The large intercooler keeps inlet
temperatures close to ambient. RSR Dual Air Fuel Ratio Gauge, TTS
MasterTune and injector / throttle body upgrades. Kits ship with rider adjustable boost 5 to 25 psi.
How much horsepower?...Well, at low boost (9 psi) 165 hp and 164
ft lns torque on a 95" Twin Cam.You can go as high as 25 psi.
One turbo kit: Three double wall boxes with all parts individually packaged. 76 pounds off to a customer.
Turbo Fuel Control
This sure does get complicated since
we've been at it for way over 30 years....From draw through SU
carburetors in 1980, to blow-though carburetion, to making our own
closed loop RSR Fuel Injection to advanced Pectel-Cosworth electronics
as well as adapting to the ever-changing Harley OEM efi systems.
We have a number of options these days...It all depends on the year of
the bike. Injectors to cover from 236 to 328 hp @ 80% Duty Cycle.
