That is a land problem in the electronic part when you have bad land that happens, it is the same as I told you before, a bad land after a while begins to burn components.

Friend, thank you for your comments, I have been very useful, I wanted more help, unfortunately in my country there are no very good electrical mechanics that we say, and those who are regular charge they charge you

could help me with one diagram that cables need to be to the ground, in which part of the motorcycles should be these, as well as those of the gasoline pump, not presisted to do it, but at least it will tell me what the mechanic is or less than what you are talking about.

I would very much appreciate your help, since I need to take it to the morning mechanic, to prevent something more serious from passing.

All electric connectors of the cars or almost everyone really have a cable either black that indicates mass, this cable can find it with a test or a test lamp you find it and put it to chassis with any bolt and you already have good lands, squema of that vehicle I do not have but with that data anyone with a basic electricity nosion can do it. Good luck greetings and an abraso.

I also decided to change the air filter and my surprise was enough to see the state of the previous filter, totally dirty and obstructed, I attach some photos, what they think. ??
