F***ked suspension?

[G4L4XY]

Had a full comprehensive service done thursday and then friday afternoon I'm riding down to hamilton and each time I go over a harsh bump I hear a loud thud! now at first I thought it was just those metal grates you ride over and you get that wierd sound.

Thing is friday morning I was riding out my driveway and it's a bit of a drop from the driveway to the road, it's not properly paved out I heard a loud pop sound like when you ride over a stone and it flicks out.

So it could be coincidence or yeah I'm not sure. Either way I will get it looked at ASAP but do you tihnk it's the forks or the suspension under the bike.

hop off the bike and give the tail some good compresses down and let it bounce back up, and do same with front forks see if they travel smoothly up and down.

then look for other sources of noise, maybe something is loose and hitting against frame etc when a big enough jolt occurs.

couldn't hurt to buy ohlins either eh, when in rome..

I've tried the above and it's fine on smaller jolts but just the real bad ones where I get the feedback. Manually pushing the bike down has produced any of the same noises`

....sounds like my Sportster on any given day...shocks aren't fucked..just dont work..

has or hasnt? you should be able to get it to near bottoming out with ur own weight. so bottom it out and let it bounce back up. If you can't get it to replicate the noise. Then the suspension itself is probably fine. and if it doesnt bind up and travels smoothly throughout its range of travel then its prob fine bro.

the noise could easily come from somewhere else, when u hit a bump there could be something else that is knocking against frame or engine etc.

good luck, pretty hard for anyone to diagnose ur problem online - can only offer suggestions.

when u hear the noise while ur riding do u also feel something unusual on the bike? if there is an issue you could hear then no doubt u would feel it too in the bikes handling

Bike A working hyobag!

Bike rear suspension should go down 10mm to 25mm when you sit on it.Get someone to measure it.
Put a couple of cable ties on the fork tubes and go for a ride then post a shot of how high they got pushed upwards.

[G4L4XY]

Sorry I meant hasn't* I will try it out though with bottoming out.

When it happens there is no feedback from the bike apart from the sound, it still handles ok

the obvious? is the suspension set up correctly? not too soft etc? gotta ask the obvious first.....
Is there any oil showing or obvious 'oily greasy crud' around the shock/linkages? if so the possibly the seal has gone....
As suggested by others, check all areas, JUST possibly a really big thump on the suspension could have damaged the linkages. check for cracks bends etc... Try riding n identical bike with same settings.. is there any difference?
I am not making ANY accusations but it has been known for sellers with fucked rear shock seals to wait till they are empty then spray the area with de greaser............

I've owned the bike for two years and its been perfectly fine. Checked the forks and suspension, appears to be no leaking oil/grease.
During the service the suspension wasn't touched (to the best of my knowledge)
Could the pop I heard the same morning have anything to do with it.

Had similar noises once after a service. Eventually found a stubby screwdriver behind a plastic panel. Only the big bumps caused it to dislodge and knock. The mechanic must've dropped it and not realised. Could be worth a look before you start replacing suspension.

[G4L4XY]

Tired compressing the front forks and the suspension and letting it go but it seems to come up just fine.
Could be a screwdriver/socket head or something haha.

Any loud noises have always been bodywork for me. Lost a bolt out of the front mudguard once and it knocked around over large bumps.

[puddytat]

Maybe the rear linkages need to be stripped & greased? Pretty minimal whats put in there by the factory. Does a Hyobung have linkages?

[gatch]

On my vfr, the brackets that hold the front mud wheel mudguard are loose on the forks. Took me ages to figure out where the rattle noise was coming from.

Check to see if the battery is securely strapped down (might be bouncing)
