LSR 2-1 Buell

When these things came out, and we were feeling sort of stupid, we custom made a few exhausts for them as well as welding up some fairing supports to keep the parts from flapping around. Jay Springsteen rode around on one we worked on.. We even got suckered into building a downdraft dual throat carb set up for a later version...we don't know what happened to that effort. We just remember not getting paid for 30 hours of work.

First, the shock, working in reverse fashion, was stuck under the bike and the exhaust was placed next to it keep it warm and to share in a common duty of snagging speed bumps. The exhaust won the ugly prize didn't do anything to help performance.

They sort of morphed into these things where all sorts of ideas get put into play. We never have understood the "Mass Centralized Muffler" idea. This seems to have come about in a historical fashion i.e. it was there before so let's keep it there. Heavy and ugly and no tuning seems to be the design mantra. Sort of a volumetric skid plate. The shock got moved up, up and away so the muffler lost a companion.

The muffler seems to have found a home down below in all models. We'll be taking a stab at Buell exhausts soon. It's a situation where the design fights a correct solution. We're used to problems like this and will be offering some new solutions.

Of course they still don't have the power to wrestle with a 600 but that's another issue we will be addressing.

06' Dual O2 Sensor Systems / RSR Air Fuel Gauges

Since we have been doing closed loop fuel injection systems for Harleys for more than 15 years and have been putting O-Sensor Ports in our exhausts for the same amount of time, we have dual O2 ports for the 06 models for our full range of exhausts. Our RSR Air Fuel Ratio Gauge is the best investment you can make for these.

New Dual O2 Meters

For EFi sequential injection our new RSR Dual Air Fuel Gauge displays the fuel mixture in both the front and rear cylinders separately. The gauge is housed in a hard anodized round enclosure in a standard 2" format with a 2.250" bezel, center back mount, with a 5/16" x 18 stainless socket head cap screw. The gauge will show fuel ratios from 17:1 to 12.0:1 (or richer). The gauge is visible in daylight and automatically dims for nighttime operation.

Scale is, left to right, lean to rich: three greens, three yellows, two orange and two red l.e.d.s.

The white arrow indicates the maximum power mixture, the second orange light, which is 13.2:1. Transitory enrichments should not, if the engine is warm (>200F Oil temp), go past the first red light. Readings at the far right side of the scale, the second red light, are simply too rich. Proper closed loop operation will cycle back and forth from green to orange around the center of the display.

It is simply the best way to evaluate the tune of your motorcycle and saves valuable dyno time. Mounted permanently. Waterproof.

Compatible with OEM narrowband sensors. Can be supplied with new high temperature Bosch narrowband sensors. Far right photo shows gauge in dim light conditions at maximum power setting.

Mounts....Roll Your Own or Buy One

Three degrees of freedom. Supplied with longer bolts for triple clamp or headlight mounting. Stainless bolts. Or get creative and roll your own. Could be as simple as one hole or a flat strap with two holes. If you want one of these they are $19.95. Part Number 06-1024. For single or dual O2 meters.

Dual O2 Ports

All LSR 2-1 exhausts can be ordered with two O2 ports. Actually O2 sensors are a really neat item. We should know, as we have a lot of experience with them. Tuning strategies are different and there are a lot of things that can go awry if you forget about temperatures, pressures etc.

Pretty soon Harleys will all be watercooled then you really won't be able to tell the difference between Milwaukee and Hammatsu. "The Man" will be sniffing your butt and planting microchips and gps modules up your ass so they can mail you a speeding ticket and keep track of your movements. They already have data recorders on your car so they know what you were doing when the biggie happened. Brave new world.
