As supplied in the past this part is a replacement dust / chain cover. This part replaces the often missing original rubber flap cover that is fitted on the generator cover to prevent chain grease messing the main engine top case. (Part 9 in the attached parts drawing photo) Part has been 3D printed as a solid part in black PETG. Fits both the LC and earlier air cooled RD 250 and RD 400 Any questions please ask.
The Replacement Yamaha RD250 350LC generator case dust cover is a perfect addition for avid motorcycle users of Yamaha RD250 or RD 250 AC motorcycles.
