Horrid clunking crunching clacking sound!!! Fazer Gen 1

[Phil]

 
Let the brakes off and reapplied to try to get some grip whereupon a horrid clunking crunching clacking sound came from beneath me.
It sounded like a cross between dropping it into first gear without the clutch and rattling a tin bucket of spanners around.
It lasted about a second, scared the crap out of me as it was loud and I'm sure I felt the bike jump, like it had gone over a speed bump.

Well that bit sounds like as the rear tyre is struggling for grip and locking up the rear end is bouncing up and down and maybe the chain is rattling against the swingarm. I've had that before at trackdays, and have seen/heard similar whilst watching races. Might not be that at all.

I've no idea what a cheap (or expensive) salad spinner sounds like.
