Lately I was changing spark plugs wire & when Istarted the bike after it had this noise, loud, when I give gas it's like somethings loose in the engine.

Hi Bugs, welcome to the forum.

'Wings can make a lot of noise if they're not running on all 4 cylinders. The fact that this started when you changed the plug wires makes me wonder if something is not connected properly.

Go back and make sure all of you connections,from the coils to the sparkplugs, are correct and tight.

Pull the plug wires one by one and hook them to a spare plug and seeif it is firing.

The clutch has a big ol' chain hooked to it. Pull in the clutch and the basket and chain stop rattling. That's the noise, but what's making them rattle? My guess is an out of balance engine. Like one running on 3 cylinders. Remember you changed the wires and this started. Right?
