andz Posted October 30, 2021 Share Posted October 30, 2021 This morning I was at a biker event and just for fun I put my 2017 Tracer on the dyno. About half an hour after the run when I started the bike to go home the check engine light is on. I had to ride home about 50km from the event, no change in performance, no funny noises or weird throttle responses. Any ideas? Link to comment Share on other sites More sharing options...
bwringer Posted October 30, 2021 Share Posted October 30, 2021 IIRC, this is known to happen if the rear wheel spins for a while without the front; the electronics assume there's a problem with one of the wheel speed sensors. I don't remember exactly what you need to do to clear this with a 2017 model, but that seems likely. 1 Link to comment Share on other sites More sharing options...

That would make sense after a dyno run of course, I was a bit surprised when they told be the bike is governed, all the others they ran on the dyno were bouncing off the rev limiter but not mine. It was a little sobering to be on the dyno straight after a Ninja that ran 309km/h top speed and this is at 1800 metres above sea level!

andz Posted October 30, 2021 Author Share Posted October 30, 2021 By the way when I lube the chain I have it on the paddock stand in 1st but the rear is barely turning so maybe there is a threshold because I haven't had this issue before. Link to comment Share on other sites More sharing options...
bwringer Posted October 30, 2021 Share Posted October 30, 2021 (edited) These bikes in stock form are governed to something like 114mph; if you get the ECU flashed they usually remove this limit. I'm not sure how much independent rear wheel rotation it takes to trigger the light, but I do know it's a common complaint, and on some models requires a dealer-only tool. Hopefully someone will come along soon with knowledge specific to the 2017 models. And please stop lubing your chain with the bike in gear... lots of fingers have been lost and de-fleshed this way.

TracerDave Posted October 30, 2021 Share Posted October 30, 2021 The 2017 model won't self clear this fault like other models. Caused by front wheel not turning when on dyno. You will need a scan tool and OBD2 to yamaha adapter lead to clear fault. 2 Link to comment Share on other sites More sharing options...

Assuming the factory spec is noted at sea level... 🤔 Edited October 31, 2021 by piotrek 1 Link to comment Share on other sites More sharing options...
andz Posted November 5, 2021 Author Share Posted November 5, 2021 I took the bike to the dealer today and they cleared the error in under ten minutes at no charge. 3 Link to comment Share on other sites More sharing options...
