There are two lessons I just can't seem to ever learn. One is not to drink to much alcohol, though it always seems like a great idea at the time. The other is not to use aftermarket parts to try to save money when OEM parts are available. I've been battling leaky carbs for a long time and tried several aftermarket float needles. They look almost identical to stock, but the carbs kept overflowing. I finally sprung for OEM needles and problem solved. I really don't understand what makes a needle worth $40 vs $2, but lesson learned.

For Keihin's, the only needles worth having are OEM or Keyster. The cheap aftermarket pieces have a soft spring that can't hold up the weight of the float. I bought a dozen Keyster's, to save on shipping cost, since I rebuild a fair number of carbs. It's also good to use a HD q-tip and brass polish to clean up the inside of the seat really well.
