On these you cant open the throttle while starting. These have an electronic safety switch that cuts out the engine if you do this. Give it a pump before pushing the start and make sure to choke. I highly recommend rejetting your quad because the hard starting is from the pilot being to lean from the factory and changing out the needle with the HRC one. Mine is set with a 45 pilot and 165 main and is as smooth as silk now. Hope this helps

Edit: your smoke is only excess fuel from pumping the throttle at the same time trying to start.

when i first bought my ktm i had troubles too. turns out that when i was playing around with the idle speed it effects the intensity of the spark on the plug, cause at one point i couldnt get it to go at all. so i took out the spark plug and turned over the starter and sure enough there was no spark. so i turned the idle screw and it came right back so i found a range where it had good spark and went from there, never had a problem since.

ive had about 5 of these quads, the trick is 2 pumps of the throttle and only choke if its cold out
