If you've got fuel coming out the overflow tubes, you might have one of a couple of problems.
There could be some trash in the float valve causing it not to close all the way.
The float could be binding against something. Again, causing the float valve not to close.
Your floats could have a leak and not be floating as they should.
Your float level could be misadjusted.
The float valve should have a smooth taper to the point at the end. If it's not smooth, it's probably not sealing.
There is a small trash screen above the float valve seat. It usually causes problems with not enough fuel rather than too much, though.
If your float system is working properly, you should never have any gas overflow unless the bike is on it's side or upside down.
Every time I have ever had gas come out an overflow/vent tube, it's been a float system issue.
If you put it on prime, the bike doesn't need to be running for fuel to fill the carb. If it comes out once the carb is full, the float system is not shutting off the fuel flow as it should.
