The throttle position sensor ( TPS ) adaptor on the carburettor is responsible for reporting the position of your throttle to the tci . The tci  uses this information to adjust the timing curve on the bike to match driving conditions.

Throttle Position Sensor

adjustment

1	Locate the throttle position sensor on the carburetor. It is found on the left hand side of the carburettor just behind the coasting enricher assembly and can be identified by its wire colours: blue, black/blue and yellow.
2	To adjust sensor idle position, connect an ohmmeter between the blue and black-blue wire terminals in the sensor side of the connector. The reading taken from the blue & black-blue wires is the maximum resistance of the TPS and isn't affected by throttle position. it should read between 4000 - 6000 Ω
3	multiply the reading  by 0.13 and 0.15 to obtain the correct range for resistance of the throttle position sensor at idle. eg: if the reading was 5500 ohms, multiply that number by 0.13 then multiply that number by 0.15. The results, 715 and 825, are the lower and upper limits of the throttle position sensor's idle reading.

4	Set the ohmmeter at R x 100 and connect it between the yellow and black/blue terminals in the sensor side of the connector. With the throttle at idle, the ohmmeter reading should be within the range established in Step 3.
5	If the ohmmeter reading is not within the specified range, loosen the throttle position sensor screws and rotate it to change its position (the ohmmeter reading will change at the same time). Once the reading is within the correct range, tighten the screws. Disconnect the ohmmeter and reconnect the electrical connector to the sensor.

testing and replacement

1	To test the sensor off the motorcycle, disconnect its electrical connector. Remove the mounting screws and take the sensor off the bike.
2	Connect an ohmmeter between the blue and black/blue terminals in the sensor electrical connector. It should indicate 4000 -6000 ohms; replace the sensor if it doesn't.
3	Connect the ohmmeter between the yellow and black/blue terminals in the connector. Turn the sensor slowly and note the reading; it should start at zero and rise to 4000 - 6000 ohms. If not, replace the sensor.
