bike still runs fine when it runs but theres a rattle/knocking from what sounds like the bottom of the engine on the cbr125,
the tappets seem fine, anyone any ideas on what else it maybe? common things maybe?

cheers

Is it only when you're riding? If so, I had something similar after I adjusted my chain - turned out to be a tight spot in it that was making the chain a bit too tight at certain points in its travel - after plenty of lubing and elimination of said tight spot, all was well again.

confused woodpecker lol made me giggle

it just when idling which makes me think it could be a clutch rattle looking at the list

there plenty of clean oil in the engine
so am i right in guesing its a new clutch to get rid of a clutch rattle?

cheers

Depends what is wrong with the clutch really mate. Is the rattle actually coming from the clutch side? could it be something stupid like a fixing rattling about?

Does revving it at a standstill make a difference?
Does it do it in neutral with and without the clutch pulled?
