guys just bought a cbr1000f 1995 model great shape well looked after it would pass for a 2 year old bike its that clean 18000 miles guy owned it this last 10 years and never took it out in the wet and it shows. anyway stole it of him for £1590. just doing the once over on her and i have noticed a bit of movement on the swinging arm NOT side ward movement but up and down movement if i grab the arm and lift it while bike is on center stand there is a bit of free play . is this normal or is there a bearing or something needs looked at in the shock. had a look online getting mixed results some say normal some say depends on the bike model . had one of these bike about 20 years ago loved it back then but cant remember if it had the free play in the shock or not up and down movement . thanks guys
