Wheel bearing size

Ok, so I've got a 78kz650c2 with the mag wheels. I can't seem to find the correct rear wheel bearing sizes. I know there are 3, two in the wheel hub and a larger one in the sprocket hub. I've done done research and have found conflicting answers. I ordered 6303-2rs 17x47x14's but the I.d. is too small for the spacer to fit in. Can anyone tell me the correct sizing for the 2 hub bearings?

Here's a place that has 2 genuine Kawasaki parts in stock:

When I replaced mine I used SKF 6205 2ZJEM bearings. Ed

From kawasaki.com parts diagrams:

BEARING BALL #6205Z 2 ea
BALL BEARING,#6206 1 ea

Do a search on Google using things like "Bearing 6205" or any other bearing number you may need, and it will show you dimensions of the bearing along with lots of places to buy one.

Z1Enterprises.com probably has wheel bearing kits for your bike. The good thing about the kits is that they include the seals. I probably would't have cleaned & lubed the speedo drive if not for that seal being included w the Fr kit --- it was easy. :blush:
