Have not done them on my sled yet but did someone else's apex at the ty fun ride.
You need to pull all the panels off, next you need to remove the panel that holds the accessory plug and ignition making sure to unplug the wiring, then I unbolted the headlamp bracket from the frame and unplugged the harness going to the head lamps and speedo. I also removed the coolant overflow bottle for more room on the right side plugs. You can squeeze past the coolant bottle to get the last coil/plug out. Then it is unbolt the coils and replace the plugs. We did it one plug at a time. Then just reverse the order to reinstall everything. As it was the 1st time doing plugs it took us about 45 min to do the job in total. Should be able to do it in 25-30 min the next time.
