i bought the bike not running, it turns over fine but i am not getting spark to the plugs. i tested the coils and they have power going into them and they get warm when ignition is on but still no spark, i also tried different plugs and still nothing... it has a box on it, a 'tr ignitor' box and this is unfamiliar to me and i am wondering it that could be the problem but i am unable to find any info online about it.
