I just picked up my 2015 Fz-09 on Thursday. I am planning on cutting off somewhere between 3/4 - 1" off each side of the handlebars and move everything in about 1.5" on each side. I would like to replace the bar end weights with a weight that extends inside the bar but only sticks out past the end of the bar less than a half inch on each side. Something like a 6" long lead bolt perhaps? The purpose is to narrow the bars for lane splitting in California. I have been looking online but have yet to find anything. I would appreciate being pointed in the right direction, someone from California must have thought of this already. Thank you.
