I am learning. Just purchased a Huffy Nel Lusso from Walmart. Wanted to go the 4 stroke route; however, it appears the 4 stroke will not fit. So.........the 2 cycle route will have to do. Really like the looks of the Nel Lusso. Should have done a little more frame size research prior to purchasing, but this a 'first timer' project and will most likely not be the last build.
