Wrap the wire round the Ht lead two or three times, it induces a signal to the Rev Counte, the wire does not have to be bare or connected to anyting other than wrapped around the lead..

is it a chronograph model? If so, reset the chrono. If not, you are going to have to send it in to a repair shop or the mfr to repair it...probably bumped it hard

This is indicating a fault code. Check Fazer forums for which one.

SOURCE: tomtom one 125 easyport mount won't stick

The soft vinyl suction cup has two ears. Behind the ears are two depressions in the mount ring. The vinyl shapes itself into the depressions and forms two tiny gaps when you try to stick it to the windshield.

Place a pencil or other small round object between the ring and the soft vinyl part. Bend the vinyl outward. You may not be able to see the difference, but it should now stick
