How is the handling of the bike at 4" over. My 2006 busa is 9" and I must say I love the stock wheel base handling a lot better. With a fender eliminator on a gen 2 you almost need to stretch it (IMO) to fill that void under the tail. I really like the look you have on that bike but I enjoy the twisties and I don't want to give up the performance. However if it's not that much different in handling I would definetly stretch mine 4" to complete the look of the rear of the bike.
