This week, I purchased a coil kit from them. The kit comes with complete instructions, leaving nothing to chance. Coils come prewired, and everything is labeled. No trips to the hardware store. They thought of everything. Doing this in the driveway, outside a messy garage, took me 55 minutes. It was well worth the price of admission. This poorly running XS1100 has little time left before the long trip to VYR. The kit just as it comes. Nothing to wire up. No trip to the hardware store. New coils in their new home. The bike runs like new!
