Years ago I also had a silly crash on my yb8, I repaired it with a fiberglass repair kit and body filler. I had an autobody paint supply shop computer scan the paint and color match it.
The b and exup grapics were done by a local decal shop and the entire thing was painted over with clear. Looked great when done, nobody could tell. Here's an after pic. Yes, those are carbon saxon wheels back in 1995.
Air tech did recently list dieci fairings as being available. My YB 8 wears this bodywork - it is an easy fit. One potential change to be mindful of is that the clip ons mount above the top triple clamp with the dieci body fitted. The benefit is that the bike is arguably more comfortable to ride.
