Hi, Anonymous and the usual suspects are:
1. Severely drained or faulty battery.
2. Faulty regulator/rectifier or high output coil.
3. Faulty power valve, solenoid or installation.
4. Clogged air filter or exhaust.
5. Cracked or incorrect float level.
6. Float needle is not seating.
7. Faulty reed valve.

SOURCE: won't idle steadily
Check the rubber boot that joins the carby to the engine to often have seen the hose clamps over tightened therefore creating a split in the rubber letting to much air in giving the rough idle eventually you wont be able to start it at all (have a good thorough look inside an outside of boot doesnt take much)

SOURCE: banshee wont rev
Usually related to TORS, specifically the safety switch in the clutch/park brake assembly. If it's defective the engine won't rev. Solution: look for a TORS removal kit.

SOURCE: 2002 YAMAHA BANSHEE WILL NOT REV
I have a 2004 banshee at the yamaha dealer being worked on.It would not run when i took it up there they cleaned the carbs and put it back together it will start but when you rev it, it holds itself wide open and wont shut down unless you pull the plug wires.they also checked the floats in the carbs said they where ok. they think it is a vent issue with the gas tank or the fuel shut off valve.IS THAT POSSIBLE

Sounds like it may be drawing air around the intake somewhere. Let it idle and spray around carefully with wd-40 until it speeds up. This will reveal the leak.
