"Also picked up a battery that I’ll put on a mini charger tomorrow at work since I don’t think it’ll start without a battery".
Years ago I had a 1984 Kawasaki 1100. I had some performance engine work done to it at one point and needed to run it a bit to break in the engine. Unfortunately, when the time came to fire it up, the bikes battery was dead. Rather than run out and buy a new battery, I figured 12 volts is 12 volts, why not just boost it off my car. I connected the cables and got the bike engine running. I pulled the cables off and the bike died ... apparently it needed a fully charged battery in it in order to run. I figured that if I could boost the bike with a car, why couldn't I just leave the cables on and run it off the car as that would save me running out for a new battery.
I started the bike again and left the cables on and the bike continued to run. After a bit though, I started to smell wiring/electrical stuff melting. I never did find out what exactly it was that was melting. The reason I mention this is, I have seen people ask (on the internet) if a bike can be boosted off a car and some say yes it can, others say no it can't. Although boosting a bike off a car may work, I suggest you do NOT use the car to keep the bike running.
Recommendation: Spend the couple of bucks and get a new battery. Your comment of "putting a mini charger on it" suggests to me that the battery you are intending to use may not be new/fresh.
That being said, some bikes will run without a battery and can be kick started ... that was not the case with my 1100, it had no kick starter and it truly did need a fully charged battery in it in order to run. I don't know what your bike will or will not do but I do know, continuing to use a car to keep a bike that needs a functioning battery in it will and did fry something in my case.
Good luck with the bike
In the end, my bike did end up with electrical issues that I tolerated until I got sick of it and sold it off VERY cheap. I occasionally raced the bike at the strip and the electrical issues could be overlooked there but trying to ride the bike on the street (wouldn't start when hot so I'd fill the tank at home before going for a "rip") was too much trouble, I gave up and sold it to the race shop that had done a bunch of the work. I was young, tired of throwing money at the bike at that point and decided to move back to cars.
I have had the odd enduro on-off road bike that worked just fine without a battery even being in the bike so, who knows ... just be careful
