welcome along sir.. as said get it to an mot station and see if they can check the bikes straight... other than that and painting it the faster yellow colour your good to go
After much deliberation and measuring today left and right hangers are not mirror images of each other the rear left kicks out moor and when viewed from the rear is quite obvious ( an extra wiggle or kick on it ) the only reason I can think of is to give extra clearance over the drive chain so explaining the extra 2cm.
