Actually, the way most wheels are made today along with the tires, most are so close to being in balance that the weights that many shops carry only make it worse. I have heard of several shops that just tack on weights opposite the valve stem just so you think they balanced the tire, and those who just don't balance tham anymore because they are so close. What it all boils down to is if you want it balanced and done right, get a wheel balancer (about $100-150) and do it yourself. And to really do it right, spin the wheel without the tire so you find the true heavy point of the wheel as its not always where the valve stem is, and mark it. When having the wheel mounted, have them put the dot to line up with that space. When this is followed, you really will have a very high chance of not needing any weights on the bike at all. Oh, when going real fast, it is good to have the stick on weights covered with duct tape - just for added security - it would suck if one came off and hurt your Busa.
