How big is your axle nut? Most of the bolts tend to be 8-12mm on the Jap bikes that I've seen. you'll probably find a couple 14mm bolts as well. Since you have a 3/8 inch ratchet, get a 3/8 1/4 reducer, a set of 1/4 drive sockets, a set of 3/8 drive sockets, and a hex set (if you have any such bolts). Make sure you have a socket large enough to remove the rear axle as well (you can get a box end wrench for that and probably have better leverage). Also, get a set of wrenches, I prefer combination wrenches, but open ended will provide more sizes for less space and money. Spend the extra money and buy quality tools, Craftsman, Husky, Kobalt all have lifetime guarantees and are readily available, this will save money in the long run since you will never have to buy the tool again. Craftsman doesn't even care how you break it. I once traded in a ratchet that had been run over by a tractor trailer, it wasn't even all there. I have also broken sockets by jumping up and down on a breaker bar trying to loosen a nut. I don't even bother buying impact sockets, I just put a 3/8 adapter on my 1/2 impact wrench and throw on a standard socket, if I break it, whatever, Sears is 2 miles away.
