Glad you found a good deal. But keep in mind, if you're running lean and it's kind of hot outside, that sensor won't last too long. Been there, done that.
In a way it's better that the sensor goes bad before something else melts in there.
Check your plugs and pay attention while riding for any signs of running lean.
Plugs are really white, carb "sneezes" at constant speed, lots of decel pop, engine running really hot are just a few hints for a lean condition.
