Noise and clanging with engine braking

[Jay z800]

Hi Admins, please remove if this is not in the right place as I am new here.

 

So I am new to the bike life and recently got a z800 and yesterday I was in gear one, pulled the throttle and let go as i was coming to the end of the road. Normally I used engine braking and my front/rear brake. As I let go of my throttle I heard a loud crunching/clanging noise below me and I could also feel something wobbling/shaking.... its only after I accelerate fast and let go...

Any help or advice?

 

Also my chain is tight, not slacking at all.

Is the bike lowered by any chance

Possibly top run of the chain hitting the swing arm on deceleration

Just my 2p worth

Agreed, that would be my first check point,

2nd would be condition of chain for tight links, chain tension, alignment

3rd would condition of both sprockets, teeth rounded

4: Cush drive, are the blocks warn, any missing

All the above, but also, wonder if the chain just needs a good lube?

Is it still doing it or is it only when you do something now?

if it’s timed with the engine speed and does it get better or worse if the clutch is in or not? 

First if its chain it will be timed with the revolution. Was it in time with the engine speed (faster you go it happens faster) and if accelerating or de accelerating - one or ethe other?
if a pin of a link is loose or the plate is very much goofed (oval over holed) and just looking at it might not look bad at first but will make a noise as it’s pushed or pulled by the forces and slam into a kinked place by the first sprocket tooth it meets then as it is partially released by the under side of the drive. I know because that happened to me traveling from the north to exmouth .

 

if the chain is too tight that can strain everything and over load.

crush drives are a possible but mostly that will be when you put it into first ull notice it or if it’s proper goosed it wil slap abit as to harsh throttle inputs but shaking? The likly hood of feeling it shaking and wobbling is extremely low unless it’s absolutely trashed them all.

check the sprockets.

if not them some deeper delving might be needed.
