Carb rebuild isn't difficult. Depends on how much crud is in there. You can count on pulling them apart at least twice (that's been my observation on users here). They can't be too clean.
Since there's a bit of cosmetic damage to the bike, take some time to re-design the stuff that's broke. Ignore the current "dashboard" and think about how you want it to look. Maybe a flat metal panel with holes in it for speedo, tach, indicator lights. Maybe an all-in-one gauge with speedo and lights. The sky's the limit to what you can do. Post ideas to this forum, and I'm confident many will chime in with their opinion. Take it for what it's worth. Me personally, I'm a bit of a purist, and like to keep things functional first, then pretty later.
