Crunching banging sounds

There's loads of crud on it. If I had a bath full of acid I'd quite
happily throw it on. The amount of gritty crap I got off of my hands
earlier on was astounding, and I didn't even touch the chain much.

I 'wash at it' and then lube it up ever 500 miles or so, that's about
once a week.

After I took the video on my phone I turned off the engine and moved
the chain up and down - it looks like its within the specified range.

Earlier on I did the "20 <something> measure" and it wasn't outside
the maximum - had about 15mm before it moved out of what the manual
describes at the servicable zone.

The last chain was replaced by the previous owner at 10,000 miles. I'm
ever so slightly heavier than he, and it's done 8,300 miles. Should I
just get it replaced now? (next payday)

Is it likely to be an expensive job to have a man replace it (How much
is a chain, and does it take an age to fit and tension) and I suppose
I could get said Man to buy/fit Scottoiler too.

 

In uk.rec.motorcycles, BGN amazed us all with this pearl of wisdom:

I concur. Try pulling the chain away from the rear sprocket. You
shouldn't be able to. A *small* amount is ok but if you can lift the
chain off the teeth more than a mm or two then a replacement is
necessary.

You are kidding right? What happened to a good old fashioned toothbrush
and half a cup of paraffin then?

You drunk the paraffin didn't you?

Ah! I see, nurturing the closet hetro. I like your style, oh wise one.

It certainly looks like it.

 

Whinging Courier says...

Can't see the point myself. A 1 1/2 inch paintbrush and an old jam jar
half filled with paraffin does me. Just make sure you put some thick
cardboard down underneath the chain run before you start. 5 litres of
paraffin cost me 3-99ukp today. I use it with a paintbrush to clean
chainlube off the white wheels and swingarm on the gixer. I used less
than half a litre to do that, clean some caked on oil from the engine
and clean the chain properly. A pair of Marigolds help too, as chainlube
is a bugger to get out of your hands.

After cleaning the chain, a 5 minute ride will be enough to get the
paraffin off the chain and get it hot enough to apply fresh chainlube
to. Do all this before cleaning the back wheel.

 

Certainly works out cheaper.

Is paraffin okay on chains, then? Do I need to wash it off with water
or anyfink before I re-lube?

 

Yet the HBoL for the Holy CG125 (makes Sign of Holy Pushrods) makes
quite clear reference to it; I remember doing mine, erm, religiously.

 

Shagged.

The only thing you wash it off with is a clean paintbrush and fresh
paraffin but it ain't really necessary. Loz's explanation is right,
especially the bit about cleaning the wheel last, after you have taken
it for a short ride.

Whoa, anyone for paralevers ?

 

BGN says...

It's the only method recommended by chain makers. You just need to get
the chain warm by riding for 5 minutes to get rid of it, and then re-
lube.

 

scruttocks says...

No, because they are a BMW thing and everyone knows BMWs are shite.

 

I always use a lot of lube. For the first few months I used 'chainsaw
oil' on it until I discovered the joys of Chain Wax then Chain Lube.

I wasn't all that hot on cleaning the chain originally though, and the
'shit' that is attached to it now has a gritty texture, which can't
have done it much good. I spent some time today with a paintbrush and
a tub of parafin getting some of the shit off, but there's still some
there.

<checks purchase receipts that came with bike>

Hmm. I haven't looked at these for a while, and there are a couple of
bits on there that I've mistaken for something else.

It appears that it's had a new "Cover, Pilot Box, Upper" - which is a
part of the clocks. So it looks like it's been pre-crashed before I
had tho opportunity.

But the one I'm more intersted in is this:

"O" Ring, 14mm. Unit £0.35, Net £0.70

I had originally thought that this was a new chain, but would that 70p
represent 2 links?

<flicks through all other receipts>

No, looks like that chain has done 18,400 miles, not the 8,400 miles I
had originally thought.

 

Right.

I got home from work, got a pot of parafin, paintbrush, pink marigolds
and packet of fags. I then spent half an hour getting the shit off.
Most of it is gone now, there was loads there.

I then got a hose-pipe and attacked my lovely shiney new rear tyre
with it to remove some of the parafin that had strayed onto the side
wall.

Off for a 4 mile bimble and back home, attacked rear tyre with hose
pipe again and then lubed up train.

Then read UKRM for a bit and spotted Verdi's post and then made the
following shocking discovery:

My chain hasn't done 8,400 miles, it's actually done 18,400 miles.

<sigh>

 

And Guzzi but without the trade name.

 

BGN? He'z just ziz guy, you know?

The grit, bound together by lube/oil will have acted like a mild
grinding agent.

So not the best thing to have on there, no.

S'why I like Scottoilers and the like - they continually drop oil on
the chain, which loosens up all that crud which flys off. Ride a few
hundred miles and you've got a nice clean chain (and a shitty orrible
back wheel - but thats not going to care, it just looks dirty)

Could be the pilot flame box for the boiler in the steam engine?

O rings are used everywhere. Rubber ones to seal all sorts of things,
metal ones in places (might have been the one on the sump plug). They
do have them in a chain (or X rings) but I've never ever heard of
anyone dismantling a chain totally and putting a new O ring in it, and
those would be more like 2mm, not 14mm.

Sofa'd.

 

It's not supposed to be spotless, you know. Cleaning chains is just
_so_ 1970s. Nowadays it's not something I bother with - all youi're
going with the lube is keeping the x- or o-ring lubricated to stop any
of the road shit getting into the bearing surface.

I prefer to use chainsaw oil, in a pump can. Much more precise
delivery. Once or twice between services seems to suffice.

The gixxer's on 15000km now and the chain's never needed significant
adjustment. Of course, it has been done at services/tyre changes, but
it's never been noticeably slack.

No. This is nothing to do with the chain. As Frag points out, there
are loads of things that use O-rings on a bike, particularly on
oilways, e.g. the oil filler cap.

Not surprising it's shot then. Stop faffing with it and get a new one.
Remeber to check the sprockets for wear too - no point in putting a
new chain on fucked ones. OTOH it does piss me off that in France even
more than England there's an assumption that you'll _always_ replace
the sprockets too. So much so that it's not actually possible to buy
just a chain on its own. Fuckers.

It's performing a lot better now. Not grinding at all. I will have
it another go over iwht parafin next week when I wash it again in hope
of getting even more shit off.

It's due for a service in just over a thousand miles, I'll ask their
opinion of it then unless it starts doing odd things. It's much
better now.
