In October 2010, we have decided to built a new air-box for the nc35. It is a big one for the new fuel injection. Luis a friend of mine help to do this kind of work. It´s the biggest airbox we made for a 400ccm bike. The airbox will be split in two parts, tank is the top part and airbox is the lower part. First, the frame will be taped. Then we form the new airbox. We take the wax plates and shape the new form. In thew last pic you can see the finished part to built a form for the airbox. Luis polished it so that we get a good result.
