FOAK: Chain and Sprox

I generally replace gearbox sprockets every chain change, and rear wheel
sprockets every other. Rear sprockets wear relatively slowly.

 

To be fair, he didn't say that Scottoilers don't extend chain life. He was
saying that they don't work in the way that most people think they do. He
is correct in asserting that o-rings are designed to seal in the chain's own
lubricant. However, he didn't take into account the fact that the o-rings
benefit from external lubrication. He also ignored the extended sprocket
life that is likely if the chain is externally oiled - which will also tend
to improve chain life as the sprocket teeth dont get worn so badly and
therefor don't put so much strain on the chain.

 

Don't the rollers need SOME FORM OF EXTERNAL LUBRICANT?

This is ukrm - we are allowed to make decisions or form impressions of

Bit late now - I've got a Tsubaki Gold chain arriving attached to
Renthal sprockets.

If it lasts 10,000 miles, it'll still be okay in 4 year's time, so I'm
not overly concerned.

Even with the way I ride I'd expect to get at least 20K miles from a
cared for chain, 25K is more the figure I'd hope to see though. 30K and
two chain repkacements says to me that you should have changed the
sprockets to give the new chain a decent chance of lasting. You've just
proved my point for me.

I said I'd had a bad experience of them, YMMV.

Tsubaki chain is good, you'll be ok with that. Tsubaki don't make
Renthal chain - Renthal make their own in Stockport. We use Renthal
sprockets on Danny's race ZX-10R, they've been fine. We use DID chain on
that bike and that's been fine too.

What do you mean "even with the way I ride"? It's well-known that you
ride like a wuss, and such low chain wear only serves to prove it.

No it doesn't. If it says anything its that slightly more frequent
lubrication (i.e. some) might have been a good idea. But in fact I
considered that a life of ~15k miles per chain was more than
satisfactory and that more time wasted on routine maintenance would
not have been economically worthwhile.

The only point it's proved is that you're more than happy to jump to
conclusions without any understanding of the individual case.

You see, getting the least possible amount of miles from ones tyres is
A Good Thing. Getting the least possible mileage from ones chain &
sprockets is A Good Thing. Getting the lowest fuel consumption from
ones riding is A Good Thing.

These things are Good Things because it makes one a Riding God.

Yeah right, and you're any quicker? I can at least claim that I ride
like a hamfisted wuss, what's your excuse?

You weren't getting 15K from a chain, you were getting more like just
over 10K. You replaced the chain twice remember. 10K from a chain means
either you never lubed it or your sprockets were fucked.

Have it your way, but I'll quite happily spend the extra 15 quid on new
sprockets and have my chains last twice as long as yours.

I won't buy another, but I never go out and buy the same things that
have failed on me prematurely in the past just to save a few quid.

I've had an EK chain snap on a ZZR1100 and the Afam on the Bandit is
like knicker elastic, I won't buy either of those again either. Both
those chains were on the bikes when I bought them and had Scottoilers
fitted too.

In all the years I've been fitting DID chain I've never had any problems
and they've lasted very well, and my experience of DID goes back many
years before I started working for the importers.

Not true as others have said. The link bearings themselves are sealed,
yes, but the roller inner & outer surfaces still need lubrication.

The external oil will also prevent, or at least reduce, rust on the
rollers and sideplates.

 

Not quickly. Just faster tha it might.

Hang on. This capiliary action is somehow transferrable to lumps of
crud?

You're confusing the link pin bearings with the rollers. The rollers
have no O-rings.

 

How the **** would you know?

Yes, it was almost new when I sold the bike.

Fine, you do that. But a) IME the sprocket sets would have been a
_lot_ more than that and b) it's not just 15 quid, is it? Fitting new
sprockets costs a lot more than a chain. Even if it's just half an
hour's extra labour charge it still makes the economics of replacing
them 'just in case' look very dodgy against the possible increase in
wear rate.

In any case, I'd just like to point out that in each case the shop
concerned was making the decision, or at least the recommendation,
that the sprockets didn't need replacing. If they could possibly have
justified it to get the extra business I'm sure they would. Your
blanket assertion that chainging the sprockets each time the chain is
replaced will double the chain life is patently absurd, as you have
nowhere near sufficient data on which to base this.

See below

I've accumulated enough knowledge and data over 28 years of looking
after my own and other people's bikes to know that changing chain alone
is false economy. But the difference between you and I is that I don't
have to think about the labour factor at the dealers, I do my
replacements myself and save far more than the cost of the sprockets by
doing so. 2 hours labour to replace chain and sprockets doubles the cost
of the replacement over doing it yourself. When I look at it from my
pont of view, 15-20 quid for the sprockets is peanuts for the added
chain life and peace of mind.

I've found the chain the most expensive bit, but I *always* buy pattern
sprockets from Mick Bull.

 

I put new sprocket on about 500 miles ago.

 

The sprockets and chain on my old gixxer were replaced at 20K miles. I never
cleaned the chain I just used Castrol Chain wax frequently.
