General consensus is "no" but if you have the equipment and weights or like the idea of dynamic balance media you might as well.
Just put KD-1s on our two Zs and I think my wife's bike has a poorly balanced front tire. At least that's what it feels like to me. Has me a little baffled because my bike is fine with a matching date code tire. And obviously install was equivalent... Any ideas?
Off the top of my head I don't recall where the dot was located on the IRC tire, tribal logic says that the valve stem isn't always the heaviest spot so maybe I screwed up my balance by lining it up with the stem. Need to run the bike on the spool stand and verify that the rear wheel is smooth. (Don't worry mom, I'll be careful)
