Front Fork Alignment (or something)

[Wookee]

First thing I would do is have a look at the rear wheel alignment marks on the swingarm then run a straight edge along the wheels, if you don't have one then pop into your MOT place and ask if they will just check it for you. If that's all ok and it's that bad that you can't adapt to it (I've had this on a previous bike and adapted to it) then the redneck way above should work!!
