The reason it smokes when you first crank it is because of the old oil/gas that was left in when you shut it off, and also theres alot of oil and gas blowby until your motor warms up fully so your piston can fit tighter in the cylinder 
Try leaning out the pilot screw if you want

...Then thats your problem, the injector mixes at 24:1. You need to block it off, using the injector with those mods is prolly screwing with your jetting.
take off the oil pump and remove the gear, put it back on then block off the lline on the carb so it doesnt suck air and start running 32:1 i think you will find it will run much better and smoke much less, i used a nipple cover from a holley carb kit to block off my oil line, there is no sense in buying the $30 kit if you have the stuff laying around unused.
from what i hear though, you can run 20:1 on any 2 stroke and it will not cease a motor, i would never try this but thats what i was told by a service technician, im going to school for powersports technician so i'll find out the truth lol, im content at 32:1
well the reason why the oil injection sux is not because of the mixing its because the plastic gear inside the injector usually breaks and then ur screwed because you don't usually know it breaks and then it stops mixing and you blow your top end
yeah that sound like furn, NOT(borat!), lol, yeah when i got my quad it was already removed, plus i was going to remove it anyway cause i always had to premix my yz125
