There is an adapter plate you can use to put a 2bbl carb on the inline, but it's much better to get the head modified (the opening is enlarged to take advantage of the 2bbl). The original distributor is a real weak point for these engines.

Nov 10, 2010 · I used to race a YZ490 (2 stroke) for those who have never riden a 400 to 500 cc 2 stroke let me fill you in. They make so much power it is just scary. If you uncorked the Polaris 2 stroke you could easily double those power ratings. Just look at their 250cc 2 stroke, they put too small of a carb on it which limited it to 22 HP.

The tsp kit adds 50% more oil across the rev range and I can tell it is using more oil now. With this new map, you do need to use the cold start switch on the carb to avoid fouling a plug at cold start since the bike has both more fuel and oil added to the map. KTM did release two new maps ending in 102 and 103 on a TSB bulletin recently.
All the research I've done on carb upgrades was something akin to a rabbit hole. So many different opinions, good and bad, pros and cons, "amal this, keihin that. carb mods kill low end, carb mods kill high end, flat slides suck, Mikuni is the best, Keihin is the best, Mikuni sucks, etc." you won't know what to think.
