Just installed the Bosch coil and the wires from cNw. Thanks Richard. Noticeable difference. Nice tight, smooth acceleration and no backfiring on decal. Pop that sucker from 65 mph to 120 in a few seconds. Not that I haven't done that before, but it positively felt stronger. The bike was a little less "glitch" from a cold start too. Replaced the battery with stock. Too many stories and even from the Yamaha dealer of having batter "warm up" for a few minutes with the Shorai. He loves his, but keeps his bikes in a heated garage. I'm sure its great, no guts no glory.
