I installed my HIDs this weekend. They have been sitting in the garage forever and I finally got around to doing it. I followed Blanca Busa's lead and went with DDM's 35 watt set with the H7 & H9 bulbs. Wanted to post this to let all know that the bulbs do not require any grinding of tabs or anything now. It's plug and play all the way. Be sure and order the setup for motorcycles.
