Chains and sprockets and tings

I need new chain and sprockets.

A smart person would have handed it all to Honda to do while it was in, but I'm not that organised. So.

1) Has anyone down south got a chain breaker / riveter I can borrow. Goose had one but he seems to have lost it.

2) If I'm replacing all that, I might as well downgear it a bit at the same time. How does one work out what's a good amount and what's a bad amount? And how do you know how much your speedo's misreading afterwards?

Ta. Thumbs Up

You dont need a chainbreaker, just use an anglegrinder to get the old one off and buy a new chain with a split link. When I changed mine I had the open-link chain clip (RIVET-LINK?) that has to be bashed on f.tight (which I did as a quick fix with a lump of metal) then rode it slowly to the shop I bought the chain from and they did it up tight for me gratis.

Not into the whole split link, riding slowly to shop with poorly fitted chain I'm afraid. I want it done properly there and then, or it's going into a shop to have the whole shebang done.

That's just me I'm afraid.

It's blind trust either way really, I'm too mechanically inept to do it myself so I've got to trust Kev/G/whoever helps me or I've got to trust the shop. I'd like to think that both take enough pride in their work not to send a bike out with a badly fitted chain. Confused

I don't trust split link chains simply cos I've heard so many people say you shouldn't use them on big bikes, and Ste's went only a couple of weeks ago. It's the sort of stupid thing that would play on my mind, call me paranoid cos I am. Neutral

Well I wasn't suggesting a split-link on a sportsbike, just your CBR Wink

I know what you mean but I've seen some workshop monkeys in action and unless you know they're coche then it is blind faith. Whereas if you've bodged it, you know it and you can accommodate this in your riding etc.

Cut the old chain off with an angle grinder (one of the most fun tools I own Laughing

), fit new parts, then fit the chain with a split link, ride it to shop, pay 'em a tenner to fit a rivet link for you with thier chain tool. Sorted. Thumbs Up

Bendy,

1 tooth down off of the front sprocket is a good amount. 2 is too many and the rear sprocket is hassle. Smile

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Hi

Smaller front sprockets will wear out the chain quicker. Not really an issue unless you go down a silly number of teeth.

M&P / MPS charge around £40 for a chain rivitting kit. Probably not the best quality, but mine is surviving occasional use. You can get proper chain splitters (I have a Whale one, where you basically clamp the chain in place, slot a pin in then beat hell out of it with a hammer), but an angle grinder is cheap and easy.

I am not unhappy with split link chains most of the time. My old FZ750 has a split link chain on it.

When do you need to replace the chain by?

All the best

Keith

Not urgently, it won't be done before Cadwell. Honda rang and offered to do it while it's in, but I want to change the sprockets and they only have standard sizes in.

I'll probably chat up someone to help me Easter weekend.
