Max39,
I would be surprised if the cover came off easily. Although, you never know.
Depending on the age of the glue and how well it was put on, you may be able to remove it.
Usually carbon is cured around 200 to 250 to 280 degrees depending on the epoxy used. If you keep the heat low enough, you may be able to remove the cover. You can try it. Maybe use a hair dryer VS a heat gun.
If the surfaces scratched or something, you could always refinish it with some wet sanding and then re-clearing of the saddle. I have had to re-clear an Evolution 2 model before. And I just re-glued the saddle cradle on an Evolution 3. The epoxy was so old that it popped free from the base. Your's you don't have to worry about that though as the rail mounts are in molded into the saddle itself.
Can't hurt to try it if it was cheap enough. But that is and was an excellent saddle.
Show us the results if you try and do it. By the way, that saddle had a weight of around 140/150gr when it was new. The Evo 2 was claimed at 99 but came in around 115/120 and the Evo 3 was around 125/135. The regular Flit with leather and padding was 190 to 200 grams. Some of the later versions had a bit more padding and reached upwards of the 220/230 gram weight range.
How that helps.
