greetings all been awhile since i posted here.

recently got a problem where my bottom cylinder spark plug ain't sparking or just doesn't spark hard enough then it leads to being covered in oil and then just doesn't fire. done about 3,000k's since own the bike and then it started, i just stripped her and re-did all the exhaust etc again , changed the plugs and then after about 180k's it's happened again. Was riding it all night and it was perfect, then at the finish of the LNR ride on the way home it occured.

i'm already using a #8 plug down from the #9 on both cylinders, and the top one is burning perfectly, the oil pump is running right as i adjusted it not too long ago and again the top cylinder is burning perfectly. so that leaves just the high tension coil ???

any feedback very much appreciated.
