Hello Yamaha fans! I've a FZ1-S from 2009.
I've a question about some error that i have on my moto.
When i acelerate, the speed gives some error, does not keep up with the speed increase. The numbers were supposed to increase with increasing speed but no. Only when I stabilize the accelerator is everything normal. Just accelerate and increase, decrease, never real. If it goes at 120km / h and suddenly accelerates, it changes to 18 after 60 but never real.
Has anyone had this? What have you done?

That's strange. I've never heard of that issue. I have an 09' myself and haven't seen anything like that. Are there any error codes showing up on the dashboard?

no, no error. I guess it can be from the speed sensor, because in this motorcycle isn't attach to the wheel.

That's the strangest thing. I've never heard about that happening. Error codes sure, but inconsistent speedo never. By chance is the bike stock? Is there anything added such as a Speedo-Healer? Just curious.
