Group: Forum Members Posts: 36, Visits: 234	After 1 year, many hours of work, 16 moulds, some carbon parts born for scrap, some of them with very short riding life, some sticking conditions from moulds to parts and vise versa, I finished my motocross carbon project! From plastic: To carbon: The loss of weight was not the main issue, the main goal of project was to make the rear fender stop cracking while riding in heavy mud and specially with supsension bottoming on bigger jumps. In muddy conditions the rear fender was bound to broke damaging also the rear side panels. Making just the rear fender in carbon didn't help very much the situation. Final solution achieved by making the three seperate plastic parts (rear mudgard and the two side panels) just in one piece. A three piece mould was needed for this purpose: Unfortunately the first mould produced a slightly wrong dimensioned part (with a lot of aesthetic problems also). The one piece tail could not fit correctly in the subframe. Both mould and part go straight to trash. Starting from scratch the mould, this time the 3 plastic parts were tighten in the subframe and the mould was produced with all of them sitting in the right position. The mk.1 part was good enough but not perfect. it last a lot of motocross riding hours but failed a little bit in very heavy mud. It was the time for mk.2 rear fender, this time more stiffer and 100 grams more heavier than mk.1. Mk.2 turned to be perfect and very good looking. It is tested in the mudiest conditions with success! The fever of carbon modification was all over me and the rest of the parts were mend to be carbon also.... Edited 9 Years Ago by Izo78
