Both styles of throttle cable are availiable aftermarket, but when they say it fits your bike, or even if they say it's for your bike, it is never set up right. For a given size venturi we can calculate the air volumes and fit jets, but if the fuel or compression or cam or exhaust is different on different bikes, just to name a few factors, then they really need different jets to suit the particular combinations the bike and market has. These aftermarket carbs are just set up with some combination of jets and needles that will give a fuel mixture that's ok and will burn, but they seldom accelerate well. They sell the same carb for commuter and sport bikes and quads. They say it fits them all. I doubt it runs well on any of them.
If you do find an exact copy of your original you can sometimes swap all the jets and slide needle and the new carb will run fairly well, but it's never guaranteed that the old jets will fit into the new carb. Different carb manufacturers use different threads for their jets, and some of the aftermarket use threads of their very own.
