Chain came off....

    Is this serious, or does it happen regularly?

    I'm only riding my bike (Yamaha fzr250) since September, so I don't have a huge amount of experience yet.

    Basically, I was driving along and kicked into second gear. When I released the clutch and gave it gas, it revved high like it was in neutral then cut out. I pulled over and noticed that my chain had come off (but was not broken). Luckily I was near home and wheeled it back. I put the chain back on by hand myself, and drove around the estate. It seems ok but when I release the clutch, it makes a rattle.

    Does this type of thing happen regularly, or should I be worried about it?

    Thanks.

    It should never happen and if it does it means that you're not looking after your chain properly. If the chain hops off it can lock the rear wheel causing you to crash, a neglected chain will eventually snap and can take a lump out of the engine case - or your leg.

    The chain needs to be lubricated regularly and adjusted properly. Check the handbook as this varies between bikes. If the chain is too slack and can't be tightened any more, it (and the sprockets) should be replaced - don't try to remove a link as when the chain is that worn there is a risk of it snapping.

    In Cavan there was a great fire / Judge McCarthy was sent to inquire / It would be a shame / If the nuns were to blame / So it had to be caused by a wire.

    Do you check your chain and sprockets on a regular basis to make sure they are in good condition and that the chain is not too slack? You must tension the chain as soon as it becomes too slack by pulling back the rear wheel.
    If you're at the max, you need to get new chain and sprockets as ninja900 explained.

    Do you make sure your chain is properly lubricated? Do you clean it and lubricate it often?

    It is important to look after this properly! You could crash or injure your leg or murder your engine if you're not careful...

    Guilty as charged. I must admit that I have never really checked the chain since I bought the bike.

    You were lucky it didn't snap or lock up the wheel. Get someone to show you how to adjust the chain. Most bikeshops will show you if you don't know anyone.

    Thanks lads. I got a mechanic friend of mine to have a look today and show me how to adjust. I'll probably replace the chain soon too.

    Don't replace the chain without replacing the sprockets wb. It's false economy... How do your sprocket teeth look at the moment? Are they really sharp and pointy?

    You could still have a lot of life left in the chain & sprockets. Just ask your friend what he thinks. Maybe a good clean of the chain with WD40 and a proper lubrication with chain wax/oil and a wheel reset will sort your problem out and you'll be good for another 2/3000km!
