I FIXED IT, YOU CAN CLOSE THE TOPIC.
Hi Friends,
From yesterday i have a little problem on my zed.
When in start up i notice that the needle goes (example 2.000 rpm) and stay there until i hit an higher rpm, example 3000. then it stuck on 3000, and so on... then some times the needle try to follow the engine rpm but with big jumps, not smoothly as the engine goes.
The problem disappear after 10 minutes of drive, and reappers when i start up again the Z after few hours.
1 - the engine runs as always,
2 - all the other gauges and tacho too.
Thanks,
Alessio
