Smoke when cranking??

So this morning I went to start my 1125r, so I disconnected the low 1 amp charger from it and it read a massive 13.8 volts on its own, so I thought that it would crank with no problem, come to find out I pressed the button and held it and it turned over 3-4 times and nothing, but then i tried it ONE more time and whaddya know it started and nothing more happened

Before it started tho I noticed a small white puff coming from where I would expect the electronic connections to be so i presumed I fried something with the massive amounts of volts from the battery OR the heat of the starter engine made the crank case vent puff out this smoke, anyway, it smelled burnt or hot.

So like any concerned citizen, I pulled the seat off and checked all my electronic connections, smelled in them etc etc, nothing, I basically tested for flow through all of them and shot electric clean down all of them and cleaned them off pretty well.

Then I tried cranking it again and whaddya know it cranked with ease.

can some trained individual shine a light on wth is going on?

also I added about a tenth more quart of oil.

Just figured out that my front o2 sensor is pulling all the volts from the rear one leaving the rear with no power.

They both start with 4 but eventually the front will pull all 8

Are you sure the smoke came from your electrical system and not the motor? A leaky fuel injector can cause partial hydro-locking making it hard to crank and sending unburnt fuel into your exhaust causing smoke. It is a different smell than burning electrical, but another possible scenario. Given hard cranking it is a possibility. Just something to think about.
