Its a valid qestion, but this isnt right im sure. Effectively if move the swingarm up and down, there is definite movement in that lower bearing/shaft which translates into a significant amount of travel at the axle end of the swinging arm.
Ive seen it in the past on other bikes, usually its a deterioration due to water ingress, jet washing being the main culprit then mixed with wet weather riding and road salt does the rest.
Although in this case the bearing and shaft seem fine. Swingarm play is an inspection check, and i just happened to check after everything was rebuilt and noticed the play, ill video it if i get a chance, if for nothing else other than reference.
This is actually my 2nd FG, my first was after passing my bike test and i sold it on, not realising what a great bike it was.
Roll forward some 15 years and nostalgia was getting the better of me. I just happened to be talking to a contractor at work and rambling on about the bike that got away, and thats when he offered me his "hedge find" complete with birds nests and spiders, where it had languished for 20 years.
I fired it up for the first time about a month ago.
It was parked up in the summer of 2003, the tax disc ran out in September of that year.
