Yes the carbs will probably need cleaned if it has set for long periods and not run by the PO. Mine is an 03 RSMV with Barons 4-2-4 Pipes and have not done any thing to the carbs. I do most of my own wrenching and have 95,000 on the clock. When you get it running right it will be almost trouble free for many miles of smiles. If you have any questions about the bike don't be shy and post it here and someone will give you an answer.
