Thanks Pleiades...!!!

There are no codes...

Yamaha Acapulco did the service and they check the bike looking for a trouble...They told me that might be a fault sensor, they even gave me the name and the price...but, to be honest I dont remember the name...

Last night, I came back home after a while running, and the engine light has already gone for about 5 minutes...
Today I havent ride the bike... I guess I*ll see ...

Also, guess I need to check my connections and contacts...as you did...
