Hello, I'm new to the forum. don't know if this is the right place to post this issue!

My 01 CBR f4i is having some Speedometer issues, every thing works when it starts up but when the bike starts to accelerate it will register the correct MPH until around 50 to 60 mph, then it starts jumping around. after it hits that point then its all off even when i come to a complete stop, accelerating it will jump form 5mph to 88mph in seconds. just trying to correct the issue or get it back to whats its suppose to register when riding.

Any help or how to correct/fix the issue would be greatly appreciated.

 

Worth having a look at the speed sensor
