Service

Well I put the Cat in for a Service @ Webbs of Eye as it had covered nearly 7,000 miles and they owed me a freeby. Didn't think it would make a whole lot of difference to the bike but wow! It's seems to have a new lease of life, quicker and smoother.

Downside is the chain has a lot of stiff links like me! So basically it needs chain and sprockets over winter. So had a search on here and it seems either Renthal or DID are the 2 names bounded about.

Finally to the question; are these still the best to go for or is there any others, I am looking for quality rather cheapy.

I had a Renthal sprocket on mine and had no probs at all.

For chains I think it's more a question of which type to go for (O-ring vs. X-ring etc.) rather than the make. And then keeping it well lubed etc.

The only make I'd positively avoid is Regina, because the one on an Aprilia RSV which I had a while ago developed a tight spot early on.

I've always used JT replacement sprockets as they seem to be easiest to get hold of, they aren't expensive and they do the job. If you don't use a genuine Yamaha front sprocket you don't get the rubber cushioning rings on either side so you can hear the links clonking over when you wheel the bike around - it can be a bit disconcerting at first.

In my experience the front sprocket starts to show signs of wear before either the chain or the rear sprocket, so I try to catch it before it gets too worn and starts to take the chain with it. I reckon that fitting a new front sprocket, which costs under a tenner for the 'Cat, can prolong chain life by 25% - say 5,000 miles or more.

Thanks for your input Bob good food for thought.

I have done 7k on the chain and sprockets and I looks like It may be the original kit so It looks like it has done 13k.

Renthal iirc don't make chains & their sprockets are usually alloy, DID also do a standard chain or a heavy duty one, I'd do a bit more homework first to be sure mate.
Also as Bob says X ring is the way to go for longevity.

X Ring allows for the chain lube to 'sink' in because of how each link is shaped. Whereas O rings tend to dry out very quickly and therefore you end up with tight spots early on.

Who would have thought chains would be such a science!

Just as well they have evolved, back a few years we'd have to take the chain off, clean it and then carefully put it in a tin of hot grease; let the gunge ooze in everywhere and then hook it out and let it hang and 'dry' / cool down before re-fitting and putting in the link and circlip making sure you got it on the right way.

Boy did that stuff fling off, wrecked my Blue Wrangler Corduroy Bell bottoms

And the Beetles were in the charts, aye Steve.

Don't Like the the sound of that pollaver.

A thought I just had, how do you dispose of the old chain and sprocket ( I don't mean the wife and kids!)?

Once removed from the motorcycle you close both your eyes and whilst holding old chain in one hand and the old sprocket in another you bend down at your waist and then make a sudden, concentrated reversed movement whilst swinging your arms over your head and momentarily releasing the said held items. Then you open your eyes and pretend that the past 2 hours of work you put into the bike never happend and tell yourself that chains never degrade and sprockets never round off.

Hang about I'm not that old, far more recent - late 70's

Now I know why I let my spanner do it

Knowing my luck I would hit someone in the church yard behind!!!!
