The K 1300 S with 175 hp, the K 1300 R with 173 hp and the K 1300 GT with 160 hp. The new K bikes feature updated transmission and clutch assembly, plus smoother engine performance and new switchgear. Von Kuenheim continues: “By raising capacity to 1300 cc, our engineers have not only increased output but also torque on all three models. At the same time the driveline was intensively revised from air/fuel mixture formation right through to the exhaust system. In this way we have been able to optimize partial load behavior as well as throttle response. Now the clutch can be operated with even less effort and with greater refinement. Shifting has been improved tangibly due to constructional changes to the gearbox and drive.” BMW is introducing new options for the 2009 as well. The popular Electronic Suspension Adjustment that first appeared on the 2005 K 1200 S has now been updated with even more on-the-fly adjustability and it’s called ESA II. Also new is the quick-shifter option, racing-style gear shift assistant, borrowed from BMW’s race-ready HP2 Sport. Automatic Stability Control (ASC) is also offered as an option on the new K bikes. “Both the K 1300 S and also the R will also have the shift assistant – familiar from the HP2 Sport – available as an option for the first time,” von Kuenheim emphasized. “We have also advanced the chassis. The new lower longitudinal strut is now made of aluminum and is thus considerably lighter. This makes the front wheel guidance response even more sensitive. The result of this comprehensive development work is superior handling, improved rideability and lower fuel consumption. The electronically adjustable suspension – called ESA in short – was launched as a world first on the K 1200 S. Now we are presenting the new, well-proven ESA II as an option for the K Series. Apart from the suspension and damping this unique system also allows the spring rate to be adjusted at the press of a button. The K Series model revision also heralds a new and innovative generation of switches and controls.

Step 1: Set the Bottoming Control This is the most important step and needs to be done first. Ideally, with the rear wheel off the ground take a measurement from the axle straight up to a fixed point on the fender (assuming the fender is mounted on the frame and not the swingarm). Then, with the motorcycle back on the ground and the rider on it, pressurize the “Bottoming Control” chamber until you get the same measurement —less 1 ¼ to 1 ½”. For example, if your first measurement was 10.0″ inches then your ending measurement should be between 8.50″ and 8.75″ inches. The difference between the two measurements is referred to as “sag”, and it should equal approximately one third of your total wheel travel (see figure 3). Another method of achieving the proper sag is it start with the bike on the ground — with no rider or load on it. Pressurize the “Bottoming Control” chamber to the highest pressure you can without exceeding 150 psi. At this point the rear wheel should be “topped out” and you need to measure from the axle straight up to a fixed point on the fender as described above. Take the same measurement with rider(s) on the bike — ready to ride. The second measurement should be 1¼” to 1½ ” less than the first. If it isn’t, then bleed off the pressure in the “Bottoming Control” chamber until the proper sag is achieved. If you intend to ride the bike at this “full height” then make sure you still put about 10 psi into the “Ride Height” chamber anyway. This helps the piston that separates the two chambers to move more freely producing a smoother ride. Step 2: Set the Ride Height After you have set the “Bottoming Control” you can now adjust the “Ride Height” chamber. This is a much simpler and less crucial adjustment to make. Simply pressurize the “Ride Height” chamber until the bike is lowered to the desired height. To raise the ride height back up, release pressure in the “Ride Height” chamber. Remember, the pressure in this chamber “holds” the bike down—the more pressure the lower it goes. Though the bike may feel “stiffer” the lower you go, do NOT re-adjust the “Bottoming Control” chamber. Essentially what’s happening here is as you’ve reduced your wheel travel, you’ve proportionally increased the forces that keep you from bottoming out with what wheel travel you have left. If you do need to re-adjust the “Bottoming Control” due the addition (or subtraction) of a passenger or extra load, release the pressure from the “Ride Height” chamber first, then repeat step 1.

1. Make sure the ignition timing is correct 2. Adjust the valves as necessary to ensure proper operation 3. Run the engine to warm it up a bit 4. Adjust the float setting. To do this, remove the carburetors (leave the throttle cables attached), remove the bowl and turn the carburetor upside down (fuel will spill). The float should look like this: Adjust as necessary by bending the float support (#37 in Figure 1). Reinstall Installation and idle adjustment 1. First you must adjust the idle. It is acceptable per the manual to adjust the idle by using the idle adjust screws (11). This usually involves screwing them then backing out 1 to 1.5 turns. Or you can adjust looking at the sliders 2. If installing the carburetors: a. Remove the cover (2) b. Reomve the slider (3) c. Place the throttle cable through the guide (18) with the spring (4) on the cable. d. Route the cable through the slide catch (6) e. Insert the slide assembly into the chamber and make sure it easily slides up and down. Direct the needle (8) into the opening of the diffuser (angled side visible). f. Screw assembly together and verify via throttle movement that slide moves freely. Attach fuel delivery lines to (12). 3. Using the idle set screw (11) raise the slider so the lower edge is 1-2 mm. 4. Assemble to engine using the proper gaskets (paper – felt – paper). 5. Using the locknut (26) adjust the free play of the throttle cable (2-3 mm) 6. Adjust the idle mixture screw – turn in completely then out 1 to 1.5 turns. * Starting using the K68′s (cold weather) 1. Verify fuel flow. Apply choke (pull 52 in Fig1). 2. Using the ticklers (13) allow fuel to enter the bowl until fuel drains from (14) 3. With the ignition off, kick 1 or 2 times 4. Turn ignition on, and as soon as engine is warmed up (maybe sooner) push choke mechanisms to open choke Idle Adjustment (engine running and warm) 1. Remove one of the spark plug caps, and with the cap shorted, adjust (11) to decrease RPM’s to a point of being minimally steady. 2. Adjust the mixture (15) out until RPM’s decrease. Turn in until RPM’s increase slightly. Then turn in screws ¼ to 1/3 revoultion. 3. Do the same for the second carburetor with the first spark plug cap shorted. 4. With both cylinders, adjust each idle (11) on each carburetor the same amount each until it’s at a steady, minimal RPM. Use small changes. (at this point you can use your airflow tool to check). 5. Sharply increase, then decrease throttle. Then engine must return to low RPMs smoothly. If the engine goes below limits, readjust (11) from step 4. Synchronization of the K68 Note: Rather than using the opposite cylinder shorted to test the pull of the live cylinder carburetor, you can use something like a Twinmax connected to the test ports (27 Fig 1). Or, if you have a model without these ports, use a Synchrometer (Appendix 2) held against the face of the carburetor. These tools merely show airflow passing through each carburetor (which is dependent on the position and wear on the slide). If using these tools, it’s not necessary to do the following steps. You wil want to use a throttle guide (Appendix 1), to show airflow at various throttle settings. Using the flow meter of your choice make sure each carburetor is the same at the various throttle settings. 1. Place the motorcycle on the center stand ensuring the rear wheel is suspended 2. Make sure you have large area to work with (safety issues here) 3. Shift into the highest gear with the engine running 4. Short one spark plug cap to the cylinder (using a nail or something in the fins) 5. Increase the speed to 40-50 km/hr 6. Fix the throttle using the throttle (maybe using a throttle stop screw under the throttle housing). 7. Reconnect other cylinder and using the opposite carburetor determine the speed which should be the same as the first. 8. Adjust the position of this slide to achieve the referenced speed using the locknut at the top of the carburetor.

Basic Tuning Adjustments 1. The following instructions are for basic fuel tuning. Modes 1,2, & 3 are allowing adjustments to increase and decrease the amount of fuel the engine needs. Modes 4 & 5 are for advanced tuning only. DO NOT change modes 4 & 5 when doing basic tuning! 2. To help understand how these modes work, you can think of them as if you were working with a carburetor. 3. Remember each time you push the MODE button you will be advancing to the next mode. Push the MODE button once and you are now in mode 1, push the MODE button again and you are now in mode 2 and so on. You only need to be concerned with modes 1, 2 & 3 for basic tuning. Modes 4 & 5 are for advanced tuning ONLY. 4. If you need to go back to the settings that were pre programmed when you purchased the controller, just look at the picture in each mode, the colored square represents where the settings were when you purchased the controller. 5. Looking at the controller you will see eight lights with numbers under them, this is what you need to look at when changing settings. The #1 light on the controller represents the leanest setting. TRINITY RACING DOES NOT TAKE REPONSIBLITY FOR DAMAGES THAT MAY OCCUR DURING OPERATION OF YOUR VEHICLE UNDER IMPROPER JET SETTINGS. IT IS THE FINAL RESPONSIBLITY OF THE OWNER/RIDER TO ADJUST JETTING TO SPECIFIC RIDING CONDITIONS AND ELEVATION BEFORE RIDING. WARNING! 1.877.FAS TOYS 2.Remove both seats 6. Re-install engine cover and seats. 6. Mode 1 green light represents idle & cruise adjustment (i.e. pilot jet). To adjust this setting push the MODE button once and then push the plus or minus buttons to adjust fuel as needed. 7. Mode 2 yellow light represents an additional amount of fuel added during acceleration (i.e. needle position). To adjust this setting, push MODE twice and then push the plus or minus buttons to adjust fuel as needed. 12 34 56 7 8 12 34 56 7 8 8. Mode 3 red light represents more fuel being added during full throttle (i.e. main jet). To adjust this setting push the MODE button three times and then push the plus or minus buttons to adjust fuel as needed. 9. If you are confident about your tuning skills and feel you need to adjust other parameters, see Advanced Tuning. 12 34 56 7 8 Advanced Tuning Adjustments 1. Advance tuning has two modes in which to adjust. They are called mode 4 and mode 5. In basic tuning, you are changing the amount of fuel that the engine receives, but with advance tuning, you will be changing when the fuel will be available. In each mode you can adjust how soon the fuel delivery occurs. 2. Mode 4 yellow light and blue light represent when the fuel delivery is available during partial throttle acceleration. To adjust this setting, push the MODE button four times and then push the plus or minus buttons to adjust fuel as needed. Only the yellow light will be changing.
