Hi! My recently purchased 2010 fuel injected 250R shoots an FI light sometimes past 8500 RPM.

I used the code reader (yellow cable thingy) and it drops 24 and 25, which seems to be the speed sensor, open or shorted cables.

I detached it from the bike, thoroughly cleaned it, used contact cleaner on all contacts, and the light still shows most times the engine goes past 8500 RPM.

Any idea about diagnosing it? Checked my service manual and it doesn't specify any procedure or check, it only says to buy a new speed sensor.

Thanks!
