ive checked allthe bolts i then fitten another chain and its ok even though it was a new chain anyway .now found pivot bearings are us it never stops pile of junkCould be the bolt that attaches the the bottom part of the rear shock to the frame. I had this clicking and checked that bolt. It is made of aluminium (WTF) and wears quickly. Greasing it up took away the clicking sound temporarily.
You can check if this is case by standing next to the bike and pushing up and down on the saddle.
