I have a 95 xlt sp that use to be a pain to start. I totally stripped down each carb and found a stuck needle valve in one carb, and stuck open chokes in two carbs. I totally cleaned everything, scrubed the chokes and put very very little 3 in 1 oil (sewing machine oil) on the chokes to ensure they would stick anymore. Also adjust your choke so that when the choke is OFF you can move the cable sheething about an 1/8 of an inch without engaging the chokes. The chokes in the carbs dont have to move a whole lot to get that gas pumping.
