i have a suzuki quadsport 230, late 80s model i think. i was riding it one day and it sputtered a few times and died. i kicked and kicked with no result, pulled it home and couldn't get spark. the plug is brand new, the plug cap fell apart when i took it off so it has been replaced and still have nothing. i check the coil with a multimeter and it checks out (have tried 2 others just in case), but i'm still not getting spark. any suggestions???
