noisy shock?

noticed when I came back from a rideout yesterday, that pushing the tail end of the Falco up and down, causes a noise around the rear shock.
it sounds like a creaky door.
I put WD40 on the linkages to see if this helped, didn,t at time but this morning the noise was gone.
went for a bit of a spin, and it was back.
suspect its either the linkages or the shock.
going on a euro tour on 19th so need to sort it.
if its the shock I presume it will just get worse, but it should remain rideable?
I will grease the linkages to be safe. shock is original.
anyone selling a simple swap ie white spring, or anything?
anyone had this happen?

Bushes?

Had the same on the Triumph, was sure it was the linkage, but it ended up being the bushes were worn, well, old.. that and the bolts going thru the metal tube in the bushes were crudded up

that makes sense, think its worse when hot, as it expands.
need to change back wheel and tyre so will give that a look this week.
many thanks.

Wd40 will fix linkages for a bit, but with evaporation and movement it will disappear pretty quick I reckon. Had a creaky NC30 once, that was linkages. Not too hard to strip and grease them, if you have some help and some way of taking the weight off the back.

Had a similar problem (sounds like it anyway) on an old Suzuki, turned out to be siezed up linkages.

Strip and regrease if you can and should be OK. Although the bushes may need a look as they can wear when all else is not well. Sounds like you're getting into it quick enough though so hopefully not a problem.

Dunno how long you've had the bike or how many miles but if you have never stripped and lubed the linkage bearings then get on and do it - especially now you have flushed crud in and grease out with that WD40.

These bearings sit in an exposed position, have little protection and are poorly greased from the start. The sooner you get onto them the less likely they will need replacing.

Look out for lots of small needle rollers as they are a loose fit !

TOO LATE

took it apart tonight to regrease, one of the rollers lost its needles!
still as long as i can get a couple and change them at the weekend, all will be well.
nothing seemed particularly stiff or mucky, but will get it all done.
had the bike just over a year, and done about 10k, had 6k on when I got it.

just ordered a pair of bearings, (supposed to be SKF or similar) for under a tenner inc postage.
company called simply bearings.
got ripped off big style by my local co, on rear wheel bearings for my XR, so chuffed to find an alternative.

Make sure the bearings you get a re "full compliment" I think that's the term and not widely spaced in a cage. The spaced out ones are not as good at handling high loads. This has been covered before, but I can't remember where, something to do with putting in a mille arm.

Don't chuck the old old bearing as you may be able to break open the new one (if it's not the right kind) and use a couple of rollers from that.

B*****ks
thats what i got!
needles not as long and spaced out more, will try to get std ones.
has anyone used these other ones?
I could get away with replacing just one, if i am stuck.
wanted to get the bike ready sat, for euro tour next fri night.
B******s

From what I recall the full compliment bearings are good for high loads, whereas the caged ones are better for high speeds.

clearly in the linkages load is the issue are speed and movement are minimal.

If I was in your predicament I would pack in the shorter rollers as a patch up and fix on return.

My thought process is that when packed in the shorter rollers (space them out around the race) can't get out of alignment and they can't be much shorter.

Anyone disagree?

Just to be clear..... are you just missing a few of the original needles?

Have you looked closely inside the bearings? They have a tendency to drop into the gap between each pair of bearing shells and are nigh on invisible there !

If all you need is a few spares to get you going I can send some spare used ones. I kept them for just this event.

PM me if needed.

Maybe one situation where sharing used needles is a good thing
