the jet and bushing are parts that they install on scooters in unrestricted states so it is a Kymco part and came unopened in the warranty and owners manual package. I just went past 200 on way home from work and dropped it off at dealer to do 200 mile maintenance on the Like and they said they would switch out parts for free while doing service and that it doesn't void warranty as they receive these parts with the scooters from manufacturer. Will pick it up tomorrow after work and let you know how it runs.
