New Vulcan Owner. Fuel, or battery?

I just bought my first motorcycle from a family member. It's the 1992 Vulcan 750. After riding once, I noticed it had a leak in one of the fuel hoses coming off the petcock.

I took off the seat, tank and then removed the two black hoses connected to the tank (the clear line looked fine so I left it alone).

I took the two hoses to Advance Auto and got some replacement hose. I cut the hoses to the correct length and installed the two hoses.

After cleanup I tried starting the bike but no luck. It would turn over when ignition was pressed, but not fire.

After a few tries, the battery had died down and was just clicking. I put it on a trickle charger overnight.

The next morning it fired up, but acted like it was a struggle to stay on. If I let it idle in neutral it will stay on, but after idling without throttle, when I roll on the throttle it dies immediately.

The fuel is in the "on" position. It has fuel in it. It's wierd that it fires up after the battery charges but then acts like it cannot stat on.

Thanks for the advice in advance. I'm happy to be a Vulcan owner.

While on the bike look down in front of your left leg. You should see a round black nob. Give it a turn. Don't remember which way but youll figure it out quick.

Do you use the choke when cold starting it?

Shouldn't run off the battery once it's fired up check your charging system and make sure u have good spark then it's probably fuel if those are good
