I actually like the antenna mirrors on my z-400. But, apparently I am just too swole for them to work properly. On the left side especially, I just cannt see around my massive 150lb, size 40 upper body, no matter how I adjust them. I was going to go with generic extenders out of some parts site or Amazon, but need to know if the left bar threads are leftie, counterclockwise-to-tighten bolts. I searched the forum, but too much irrelevant info comes up. I asked on a riding forum, and got bombed with people saying bar-ends are the only way to go, and that has absolutely no appeal to me. Thank you in advance for you help, most appreciated!
