Good for you!
You might need the choke to start and then very soon after have to turn off the choke to keep her running...
You pretty much want to keep heat/spark away from fuel, so you should clean up your fuel line routing a bit, and do whatever you need to do to stop all the fuel leaks, we don't want to burn up here, so be careful!
Your chain looks a bit slack, you probably need to relocate the tensioner a bit since its already at its top position, so you can tension the chain a bit more (unless you find the ride is smooth like this, then leave it alone). I am a fan of running without a tensioner, so if this were my bike I would probably pull a link out of the chain and try to get the tension right without the tensioner by adjusting the motor and rear wheel position. If you want to try and do this the easiest thing for you to do (since you have a nice heavy chain there) is take the cheap kit chain and make it one link shorter than your current chain, then try and setup the bike with the shorter chain. If it works out then shorten the heavy duty chain, if not then go back what you got now. That tensioner roller put too much drag on the bike when pedaling for my liking, and made too much noise, so it had to go.... so I said good riddens.....
