Banshee sounds weird

[Owlbert]

Ok guys I have an 04 banshee and it ran great last weekend now when you start it it don't wanna idle and when you rev it up it sounds weird kinda sounds like it's muffled anyone know what the problem might be

Your carbs mite not be synced. Or the air mix screw isn't correct. My bike is running lean. I think it's because my jets are small need bigger jets.

Clogged jet, dirty carb, old fuel, fouled plug, loose packing, mouse nest.

Or tors.

Tors and park break have been eliminated

Have they been disabled electronically?

Yeah it started acting up last weekend it was like the throttle was stuck so I shut it off and bumped the throttle a couple times and it was fine for awhile and then it did it again a little while late so I did the same thing then it ran fine for the rest of the day and I parked it in the garage and went to start it yesterday and that's when it sounded weird

Dunno, seems like two different stories. Second description sounds like air leak/runaway engine.

I suggest compression and leakdown test.

this. Does it not idle and almost die? Or runaway?

had this problem after i cut my parking brake. a friend of mine was dicking around with the wires but i cant remember right off the bat when he touched the wires together or pulled them apart. it ran perfect. had same problems, wouldnt idle, ran crappy. felt like the throttle was stuck closed. (not stuck open) check wiring if your still having problems.
