Hi Guys.
Thanks for all your help. I checked today my moto and I think that it's a bigger problem. The speedo rotor looks like a new. I was really surprised! I checked all the cables and the there is the power, so I think that maybe it's a speedo sensor
₤102! I don't know what can cause this problem if the speedo rotor is ok. Do you know maybe where can I find a cheeper speedo sensor, I checked ebay but there is nothing for SV.
