Noisy bike...

[Paul smith]

..there,s an annoying sound coming from the bike, a sort of clicking/ticking/grinding noise...only happens when in the lowest gear an seems to be getting worse/louder especially when going up hills..it,s not the drivechain or the motor...any thoughts?...lowest gear can still be used..doesn,t jump or anything..

This is the area, on both sides of the swing arm. There are two biker with problems at the fs600. Not sure if they heared some noise before?! I have also vibrations just in the lowest gear in the frame or motor while riding smooth up.

Not helpful, but a case of test and trial I'm afraid. Mine ended up being carbon seat post, but I swore blind noise was from crank.
