i seem to have a gas leak. gas is running down from the carb to the air box any ideas

Fuel tap and / or carb float, needle valve.

Tap is easy enough to check. Undo the fuel supply line. There should be nothing coming out. If you are getting fuel coming out, the tap is bad.

Here is a good video on cleaning your needle valve:

Be sure to check your oil. I'd drain it and see if you have fuel in your oil.

I've just had this same problem. The float needle got moved somehow and wasn't properly placed. Re-set the float needle and it works fine now.

If the roads you ride on is rough and uneven with potholes and such, the float level adjustment may have changed causing the fuel level in the float bowl to be too high. It's an easy fix, but does require removal of the carb to make the adjustment.
