I would imagine a chain that has stood for two years and has 'really bad rust' will need replacing as many of the links will have probably seized.

However, if you want to give it ago I'd use a stiff brush and some paraffin.

[Dazbo666]

Maybe a spark plug brush, and paraffin, then re-oil it....
but expect to have to replace the chain VERY soon

Take it off the bike and leave overnight in a pan of vinegar - then as above.

When I got my boy his KTM the chain was pretty much locked solid with rust in most places. Did nothing other than leave it in an oil bath for almost six months, with an occasional poke. Didn't expect much, but surprisingly it worked, and is still going strong today!

When i bought my vtr it had been sat for a year and the chain was pretty rusty. just oiled it before i first rode it and when i got back gave it a good scrub and that was 99% of the rust gone, I would make sure all the links are free first.... have adjusted the chain 3 times in 5000 miles.

As most have said, check the chain for tight links.

Get the rear wheel off the ground and give it a close inspection and lube it to the extreme...

what i do if a chain needs a really good clean but is beyond repair is as follows.

1) take chain in hand and looosed links up as much as possible.

2) get that old tray of engine oil you never get round to pouring down the drain because its outside your neibours house.

3)put chain in so its submerged totally and leave for a couple of days.

4)take chain out and it SHOULD be nice and free and smooth.

5)clean all crap off with parafin and very stiff brush

6) clean in hot soapy water then lube thoroughly.

but factor in your time and the cost of parafin lube ect maybe just treat him to a new o ring its nearly crimbo anyway sausage.

good luck and merry christmas.

Oil doesn't get rid of rust. Any chain recovered by putting in an oilbath couldn't have been too bad in the first place. My suggestion is change it for a new one coz if it snaps it might cost you an engine - or worse.

Yeah, if it’s bad get a new chain. My CBR600 had been stood when I first bought it and the chain was dry and heavily rusted. I decided to lube it and see how it went. The chain needed almost daily adjustment and reached the wear limit in a few hundred miles.

Even worse with mine was the corrosion on the front brake pads which ended up with the friction material falling off one pad. I was zooming along the A404 when something heavy hit my boot. Couldn’t see anything amiss so carried on to the next junction. Left the main road and nearly shat myself when the brake lever came back to the bar with no resistance. Queue furious pumping on the lever and stamping on the back brake.

Rust in your underpants FTL.

Hi

If an O ring chain then unlikely that there is any rust anywhere critical. If there is then the O rings are shot anyway so the chain is scrap.

Check for any stiff links. If there are any it suggests the lube has escaped from that link and so the sealing wrings are knackered (although could also be a bent pin on that link).

If you want to clean it up then I would use a toothbrush and some oil. Wouldn't worry about which oil too much (maybe used engine oil). Just scrub it up a bit.

All the best

chris-red whats the differnce in using an off the shelf chain cleaner as apposed to a bottle of fairy and some hot water then re lubing.

the op asked how to clean his chain and theres been some suggestions,nobody said it was the best way to protect or prolong the life of a chain just how to clean up a rusty one.

if it was me and i was going to keep the bike rather than sell it on id buy a new one as fixing an old rusty one is false economy when you factor in the recovery of your bike when it snapps miles from hope.

if i were to be cleaning the bike up to sell on then id do as most have suggested and just clean it and lube it.

I agree with these guys, Buy a new chain. Its not worth the risk of it snapping on you

Well rust can be removed with rust remover, so your old chain might look ok on the outside but what about the insides? Well in the old days you could buy a tin of chain grease, heat it up then dip the chain in it to lube it. But modern chains aren’t made for that sort of DIY fixing.

If that chain has worn inside and snaps, you are looking at a nasty potentially lethal accident and a heck of a lot of expensive damage like a chunk ripped out of the engine casing (seen it happen to a ZZR1100).

I’m afraid I have to go with the others, cheapest fix in the short term is a new chain, and you might as well replace the sprockets whilst you’re doing that.

Also two years off road, I think your going to need to check literally everything first for storage wear, re-grease all bearing, strip the brakes, clean and put in new seals. Having just restored my old GPz900 after sitting in a garage you’d be surprised what can end up needing repairs.

dunk it in petrol as tho it will make the rust come off easier and after that use a hard brush probs a wire brush will do it put paraffin on it brush it untill it comes off.
