Shimano derailer spring tightening

Hi, i just bought a bike with a shimano rear derailer. Im used to sram, and as soon as i started riding the bike, the chain was flapping about like there,s no tomorrow. The chain was actually slapping against the spokes too.

Do all shimano xt rear derailers behave like this? is there any way i can tighten it?

If it is a new derailleur this sounds like an installation problem. Check the installation and chain routing.

Anyway you can post a picture of the drivetrain? There's many possible problems and adjustments that affect this.

FWIW: Shimano XT derailleurs have served me perfectly for many, many years. My bikes typically have 3 times as much chain as uprights, so chain control is important. The only problems I've had were after 10 years and many thousands of miles:

Most likely the chain isn't routed through the RD cage correctly...
