A fuel leak is a very serious problem, especially on a motorcycle where the gas tank is located immediately next to the engine/leak area, unlike a car where it is completely on the opposite end of the vehicle. If you don't feel you can safely perform this maintenance, don't, and take it to a mechanic.
In my experience on other bikes, the only way you are going to find the source is to remove everything from the bike so you have at least flashlight-visible access to the entire fuel delivery system. I prefer to fill every gap I can with balled up paper towels to prevent the fuel from pooling, and I quickly replace them from the engine so they don't catch fire themselves.
Then, start the bike cold. Depending on where the problem lies, it may leak immediately, it may leak during warm-up, it may leak after getting completely warmed up, or more than one of the previous two. Don't assume that because you found one leak you have found all of the leaks
If you can't get the leak to start with the bike running in your driveway, then go for short rides with the fuel delivery system still fully visible - you may need to zip-tie some dangling components - and stop regularly to see if the leak has started up again.
Also, don't let the bike get hot if you feel it is going to start on fire - like if it's dripping gas on an exhaust manifold or other very hot component.
