Default 1978 gs400

is it possible to idle the bike without rejetting? as of right now it only runs on choke, it will not run or start without the choke on. i have modified the exhaust and also changed to cone air filters. my guess is the bike is running to lean. any idea where i can get jets or if any jets from another bike will fit? i cant find any available jet kits for gs400 so if the jets from a gs550 will work i can buy a gs550 jet kit to rejet. they are mikuni carbs. thank you
