When I bought my xb12 I was having similar problems. It turned out that there were cracks in the spark plug boots and it was throwing spark all over. I'd check both the spark plug end and the coil end of your boots for cracks or wear. And when you throw them back on or replace them make sure to smear some dielectric grease into the boot. Good luck
