Kevin30 Posted July 21, 2021 Share Posted July 21, 2021 Hey everyone, I have owned a 2020 tracer 900gt for 6 months now, bought it new. Put around 3000km on it before I took it on a trip (about 5500km) Before the trip I never had any issues with it. During the trip I encountered an issue where I would turn the key, start the engine and my idle speed would be 600/700 (way too low and it sounds like it would stall at any moment) and at the same time my throttle would do nothing when I twist it. If I keep turning off the key and back on and start the engine eventually the issue would go away (I discovered) I encountered this issue over 10 times while riding back home. When the motorcycle runs fine it stays fine, so it wont happen while riding. The issue only happens when twisting the key and then starting the engine. I can ride for 300km, turn it off for fuel, turn it back on and the problem happens so it doesnt matter if its a cold or hot start. It doesnt happen everytime, sometimes it does and sometimes it doesnt. My check engine light is on, since im back in my country I took it to the dealer now who will take a look at it. But im very curious if any of you guys have had this problem or have an idea of what it could be? Thanks in advance, Link to comment Share on other sites More sharing options...
peteinpa Posted July 21, 2021 Share Posted July 21, 2021 Wonder if you have a bad ignition switch or solder joints to the switch. Link to comment Share on other sites More sharing options...
ilanr1 Posted July 21, 2021 Share Posted July 21, 2021 (edited) Hi , just clean the throttle bodies. It's a known issue... Edited July 21, 2021 by ilanr1 Link to comment Share on other sites More sharing options...

First time I heard this coming up....do you have any links talking about this? Its probably the ignition switch by the way Link to comment Share on other sites More sharing options...
Kevin30 Posted July 21, 2021 Author Share Posted July 21, 2021 Thanks for the replies so far. The dealer also thought it was related to the electrical part, they will hook it up to the computer and read the error. But to me (as someone with little technical knowledge) how can the ignition switch make the engine idle at a wrong speed and disable the throttle from working?

NormR Posted July 21, 2021 Share Posted July 21, 2021 (edited) It occurred on my FZ1. But my FZ had over 80,000kms on her when it starting giving me that problem. There was a faulty wire that was shorting occasionally and cutting the motors revs. It was like the bike was stalling. Took the switch off and had it repaired. No more problems. It might be something else but have that checked. At least yours is still on warranty Edited July 21, 2021 by NormR Link to comment Share on other sites More sharing options...

A dirty switch might not allow full current potential to all the FI circuits, etc -especially after the starter is asked to rotate the engine. The FI system requires a minimum of 12.3-12.5 Vdc in order to operate correctly. -Skip 1 Link to comment Share on other sites More sharing options...
Kevin30 Posted July 21, 2021 Author Share Posted July 21, 2021 I will keep you guys updated once I hear back from the dealership what ends up being their thoughts and decision It was kind of a bummer it happened during a trip as it ment I couldnt rely on the motorcycle anymore and had to get back home Link to comment Share on other sites More sharing options...

Makes you wonder where you'll get stranded. Hopefully the deaker will i d the problem surely and quickly. Link to comment Share on other sites More sharing options...
Kevin30 Posted July 24, 2021 Author Share Posted July 24, 2021 Incase someone is interested, I got the motorcycle back since today. They told me there was a calibration issue with the throttle. The value was off and the sensor picks it up and locks the throttle as a result. That was also the fault code it had. Now everything seems good (so far) but they assured me it would never happen again. 6 Link to comment Share on other sites More sharing options...

petshark Posted July 24, 2021 Share Posted July 24, 2021 (edited) Did you change the throttle cable free play by any chance? After my dealer rode my Tracer to diagnose an unrelated issue, he commented on this. I had it set to the absolute minimum to reduce the on/off feel and the more immediate response. He told me to take the manual spec of 3-5 mm play seriously as setting it below that range can cause the sensor to not fully return to zero and that creates all kinds of problems in the ECU. I stubbornly insisted that it doesn't need 3 mm from zero, it can also be 1 mm or even less and zero would still be zero as long as the cable is not pulled in. I could turn the handlebars to full lock without noticing any change in RPM so I was sure there was no problem but I loosened it a little just to be sure... Not enough he said on a later date. Recently while troubleshooting problems I finally gave in and set it at 5 mm just to exclude it as a cause. I've since solved everything and I can't be sure that changing that setting was not part of the solution. I've settled on 3 mm and am now less likely to rebel against the manufacturers recommendations. 😇 Edited July 24, 2021 by petshark Link to comment Share on other sites More sharing options...

And the wheel is almost completely out so the next adjustment will need to happen at the other part of the cable. My throttle response hadnt changed since when I picked it up with 0km on it as far as i can tell. If the throttle cable gets more free play it should be seen during maintenances before its a problem or not? it has 8600km now in 6 months which isnt that much, it shouldnt happened in between maintenances I assume? and at 10.000 it will go in for a regular maintenance.

It was a long shot. If you didn't adjust the free play, it can only have gotten a little looser from the cable stretching. I don't think your issue can be related to this. So it's still a mystery to me but I'm glad they sorted it out under warranty. Hopefully you can resume that trip in the near future. Btw, great to see another Belgian on the forum. 😎 Link to comment Share on other sites More sharing options...
