Here's a quick overview how I made a plug and one piece fibreglass mold for replicating '85-89 Honda CR250R rear fender out of carbon fibre. I used same method with front fender I posted earlier so I won't go through steps here with same detail.
I'm pretty pleased with the result. I only used two layers of carbon fibre cloth which ended up with a very light part. I might do another one later with three layers of cloth to achieve a bit stronger and less flexible piece.
Next steps would be to make a lower piece for the rear fender and a seat pan out of carbon fibre. I have not fully figured out yet how to make plugs and molds for those pieces. I've also been planning modifications to my '01 Honda CBR600F4i PC35. Hopefully I can figure those out and share some of them within this year. Happy new year!
