Don't forget that if your bike has the big, plastic, 3D, Marauder logo on the tank, instead of the flat Suzuki "S", then it's the Canadian/European version (like mine). This means that the carb is set up richer than the American bikes. They run weak to comply with the American nanny laws, so ignore anything on here about carb mods. I find that I rarely need the choke, but the rule of thumb is - if it needs choke to start, then use it. You're not going to do any harm either way.
