What should be the resistance between clock, and data on an I²C bus?

trying some i2c devices, though they aren't working, so i thought maybe they where shorting, my cheap multimiter reads 3kohm, is it suposed to be like this?

the device is a cheap ebay nunchuck, made myself a wiichuck adapter with vero board, though i'm measuring the resistance directly from the original socket, so it's not my homemade adaptor thats causing the probems...
