I expect the TPS resistance to be slightly higher to get 157mv. See link above. Remember that the throttle must be closed fully, which is below idle. So should we be measuring with the ignition on?

swooshdave Posted August 12 Author Share Posted August 12 Anyone remember which coil wire goes to which coil? SX and OX? The workshop manual is a copy and doesn’t have the legend. Link to comment Share on other sites More sharing options...

Google Translate helped us too. Which leads us to believe the wires were actually crossed! The one thing I didn’t trust is if the Italians to map stuff while sitting on the bikes. 😜 Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk No, not the same thing! That is just some ridiculous coincidence that shows "1.57!" The TPS is set in millivolts (mV) to 157 mV with the throttle plate completely closed. Resistance (Ohms/Ω) are not used to baseline the TPS. Reference (and perform) the "Decent Tune-up" . . . 1 Link to comment Share on other sites More sharing options...

Can you update the Decent Tune Up post to say that you have to turn the ignition on for the test. I know it should be apparent but… Link to comment Share on other sites More sharing options...

I know it should be apparent but… Sure. You are talking about the TPS procedure, yes? Done. Thanks, @swooshdave! "With a quality voltmeter, connect the positive to the violet/black wire and the negative to the violet (the yellow is not used for this setting). With the Run Switch on, switch on the keyed Ignition Switch. Adjust the TPS to 157 milivolts " 1 1 Link to comment Share on other sites More sharing options...

swooshdave Posted August 13 Author Share Posted August 13 18 hours ago, MartyNZ said: I think it's possible to swap the ignition coil supply leads. Could the same thing happen to the injector leads? Ding ding ding, we have a winner! It was the ignition coil supply leads! Pretty sure the misadjusted TPS (it wasn’t right before I screwed it up) didn’t help. It sounds spectacular! 2 1 Link to comment Share on other sites More sharing options...
docc Posted August 13 Share Posted August 13 Just so I understand, the electrical power to the void was connected wrong (right to left)? Link to comment Share on other sites More sharing options...

The good news is the power wires to the coils are marked. Which is nice if you know Italian or are handy with Google Translate. Actually my friend’s wife spent time in Italy and we could have asked her too. He had replaced the TPS screws and could have easily bumped it too. Regardless, it now sounds amazing. He’s got the FbF mufflers and a Power Commander. Edited August 13 by swooshdave 1 Link to comment Share on other sites More sharing options...
