Hi all, a quick question
I have just replaced chain and sprockets, I thought I would go with a replacement OEM front sprocket thought the rubber dampner was a good idea, DID 530 chain and renthal rear.
Well as you can hopefully see from the pic when the chain starts to run onto the sprocket the roller seems to sit on top of the tooth instead of meshing nicely in between the teeth. Is this the rubber dampner stopping the chain sitting right in the teeth or does aftermarket sprockets do this? I have noticed the points of the teeth are square, after market ones are pointed aren't they? Will it bed in and correct itself?
When I spin the wheel its makes quite a clunking noise as the roller drops into the grooves and surly this will cause rapid wear on both sprocket and chain. The old sprocket was hooked quite badly, but there was big indentations in the rubber where the chain had bedded in. Sorry more than one question

before you took this pic were you turning the back wheel by hand?

during normal operation the top section of the chain is under tension, not the bottom. all i can see in this pic is chain slack piling against the sprocket due to the slack being on the top. i don't think you have a problem at all here.

Not sure what you mean by the rubber dampner. If you are talking about the slider that runs along the swing arm, make sure that is in good condition. They are $40 plus shipping on the net and can be installed while you have the front cover off. I just did one on my bike as the old rubber slider broke apart.

As far as the sprocket, that is exactly what it SHOULD look like. Grab a socket, place it on the front and turn it counter clockwise to simulate how the gear will pull the chain. It should mesh smoothly no matter which direction, and the 16t is OEM size.

Cheers for replying, the rubber dampner is the part of the sprocket that has the writing on it in the pic, it is moulded onto the sprocket. I think its to dampen the noise. Anyway I have now fitted a renthal front as well and no problem anymore, no clunking noise or bouncing chain. The pointed teeth allow the chain to run smoothly onto the sprocket.

Pointy teeth or not, the chain should ride smoothly into the sprocket regardless and it should seat easily down into the valley for a perfect mesh, especially on brand new parts. I'm wondering if you just got a sprocket that was machined incorrectly?

Oh well, as long as you are happy with the results.
