A 65cc metrakit with stock pipe and carb will work. Won't be very fast, but will have nice torque. Good for daily commuting.
Personally I'd invest in a pipe too, as that adds a little bit of overall power. Something like a Proma circuit (Great overall power, good combination with the metra) or a Tecno Estoril, as a lot of people are fond of that pipe.
The carb will do. Gets you great mileage. If you invest in a different carb, I'd go for a 15mm or 16mm for daily commuting. Adding a bigger carb will give you more overall power. Especially low and mid-range. It will use a bit more fuel, but nothing too drastic.
