The oil is half way up the site glass, so its good now. Thank goodness! lol. The oil doesnt smell like gas, and I had a lot of it to smell. My buddy wanted to set the idle to the "thumping of a Harley" but I told him that wasnt right. He wants it to be cool, not right lol. It seems to be a little high right now but ill go out and mess with it a bit more today if I can

Eureka! ... kinda. I took it out today to ride around my apt complex, to get a feel for things and see how its riding. As I said before the idle seemed to be a little high but a few people have told me thats ok, better high than low. Well when I get it out of the garage, into gear, and get out of the friction zone and give it a little throttle, it starts to bog down. Bog down as in I roll on the throttle and it starts to die. I made it to a stop sign by my mailbox and it completely died, and I couldnt get it started again. So I pushed it back to the garage, not a big deal, I needed the exercise anyways lol.

Now the conditions are a bit cold here in Colorado today, and my battery was left in the bike for a few days. I took it out and put it on the trickle while I was out getting parts (to wire up my tail light), but that was only for about an hour. It was hard to start, and I had to use some starter fluid, but I think thats because of my battery not being fully charged. I cant seem to stabilize my idle either, some times its really high, sometimes it really low.

Does this sound like a problem anybody else has run into before?

Many battery tenders come with installable pigtails.  They are intended to be left connected to the battery.  You just pull the cord and away you go.

To just leave some wire hanging, I'm not so sure about.  If the + hits anything grounded you're possibly going to have a wire melt-down situation with no fusing to stop the melt.  Might start a fire, might just burn into two pieces, might melt through the side of your battery, might just spark and bounce off.  You'll need a way to thoroughly insulate the + wire when not connected to the charger.
