My change is all here - be warned 6 pages http://foc-u.co.uk/index.php/topic,25205.125.html

[Middy2000]

I'm now thinking this is the issue I have with my bike.  Only when cold does it do it.  First couple of junctions I get the clunk as I set off.  Don't notice it in any other gear but then the noise maybe drowns it out. 

She's a 2001 and just clocked up 10,000 miles.  Would the front sprocket be worn this quick?

[unfazed]

Short answer, Yes.

[Middy2000]

Precise and to the point. Like it.


What's the longer term diagnosis of running it like this. To be fair iit' been like it 6 months already.


Will it last a few more miles until I lay her up over winter and then I'll fit new chain and sprocket? I take it I'm risking the chain snagging and totally screwing the sprocket?

Or if it is because of a badly seised couple of links then you could be risking a snapped chain. I tried to ignore mine for as long as I could but couldn't really relax and enjoy my rides. If you are only slow commuting then you may decide to take a risk.

If you mean it clunks between gears, or as you put it into gear, thats not the same issue. Thats chain tension.

Yep Mr sharp, followed your change when you were doing it and theres some good links in there too . Have been looking at some adds but haven't made up mind on which way to go yet :rolleyes . Started my shopping with the easiest option , new rear tyre, Pilot Road 4.  
Was also looking at front brake discs and got a big shock :eek , they aren't cheep. And again there are so many options . Think ill be doing a bit more research on these before I choose.

Might just change the chain and sprocket.  That'll sort it either way.  Any recommendations on both?

[TOM VR46]

Middy have a look at fazersharp link to his change . It will give you a good place to start deciding what you want for your bike. Im still thinking about what I want. I do like the idea of these noise reduction sprockets.

My son had it on his bike and lasted the same as any other sprocket he had.


JT sprockets do them now also http://www.jtsprockets.com/catalogue/sprocket/JTF513RB/

[TOM VR46]

Just wee update. Fitted new tyre at weekend . Today new chain and sprocket arrived with wee surprise. After much head scratching :rolleyes over chain and sprocket sets I decided to just go for what to me was a normal choice, nothing fancy, - Yamaha FZS600 Fazer 1998 to 2003 Silver X-Ring JT Chain & JT Sprocket Kit Set[color=rgb(51, 51, 51)][font=] - off ebay. I was going to order silent front sprocket too but forgot to add to order, so left it off. But today opened the box and set ,,,  comes with JTF513.15RB rubber dampened front sprocket. So chuffed with that . [/font][/color]
[color=rgb(51, 51, 51)][font=]Now just waiting on new riveting tool as I couldn't find my old one. Hopefully it will be here this week.[/font][/color]

[fazersharp]

Not sure if the "silent" front sprocket makes any difference but the manufacturer tells me it does so I went for it on the front as that is what was OEM but I did not bother with the back silent one. 

[TOM VR46]

ahh, still trying to attach pic.

[TOM VR46]

Well nothing is going right today. :'( . The pic should have been in the post, but instead you get two pics , no post. So as you can see I have broke one of the pins. :eek . All was going well until I decided to give that one another quarter of a turn,,,,,,, and I don't know why. So now waiting on new joining link. Hope this works.  :rolleyes

What tool are you using to flare the rivet? From the picture, you went off centre which is usually caused by the riveter not being set up incorrectly. General the flare should be not be less than .3mm or more than .6mm of the thickness of the rivet. I generally go for .5mm measured with a vernier to be sure.

[TOM VR46]

Sorry the pic isn't the best. Ive got just a basic flaring tool of ebay. But the flare part of the set didn't seem to good so I made a part which gave a little bit more of a spread to the pin. The part that came with the set seemed as if it would have been apply direct pressure without any flare. I do have a Vernier but the display is working properly so I cant say how much im flaring the pin but it wasn't a lot. If I had have stopped and not gone that little bit more it looked ok. But I do have a habit of just a wee touch more, and this is the usual result. Not as bad as when I was younger but is still snap things every now and again. But ill know the next time, which will probably be next weekend.

Had a mate back in the 60's, who had a bad habit of overdoing it with spanners. We called him Screech  :lol .

What was the tool.
I used this one youtube.com/watch?v=skX2GhrB2Oc
STUPID VID WONT LINK, copy and paste this youtube.com/watch?v=skX2GhrB2Oc and add the www.Its by Afam Although I did think afterwards that the pin that does the pressing into the hole looked a little worn after I had done the two link pins. Not sure if it would do such the same good job if used again. 

[unfazed]

Is this the type you have?

It was the same as unfazed. But, as in unfazed pic , the flare pin , you can see clearly the point that would enter the pin on link to be flared.
The set I got  , if you had taken pic at same angle as in unfazed pic , you would not have seen as much of the point. When I held it up to the link to be flared , the point was in the hollow and flush with the face, this to me  would not have done any flaring.
So, after a bit of head scratching and looking through old tools I found a small punch , similar to tool one in the picture. A little bit of work and it looked ok. The point was same size as the hollow in link , but has more of an angle to flare.
The thing I got wrong was just the pressure, because you are flaring to such a small degree,  it would have been ok if I had not gone for the last wee tweek on it. My fault  :\
But the tool in unfazed pic looks a lot better than the one I got.
