I got this bike in Feb. When I got it it leaked gas from the float bowl gasket I replaced them but it didn't seat right and leaked still I reseated it again and stopped the gas leak. Now all of a sudden it's leaking a bit of gas from the new fuel line from gas tank to the t joint. It will start and rough idle like it wants to go at a few hundred RPM then cuts out and dies and not every time but alot it will back fire. Anyone have any suggestions I'm pretty lost with this and it's finally warm enough to ride I need help to get on the road

 

Sounds like your choke isn't working. Hondas are notoriously lean starters. You also need to check your vacuum line to your fuel petcock. Check number one cylinder to make sure the vac line fitting has a hose on it or is capped.
