hey hows it going ,

OK firstly im very green when it comes to all this first bike and no real experience at this , right so started bike this morning and it just doesn’t sound right.Had a quick glance when I got home and could see sparks like an electronic lighter makes coming from under the tank if someone could just give me an idea of what it might be and how serious it is id appreciate it going to take it to mechanic at weekend but all ill think about till then is what might it be so any info might put my mind at rest , Bike Hornet 600

Thanks
