Whining from front sprocket area

[Andy-Fazer-thou]

Hi All
I have recently got my Fazer 1000 all up and running again after a bit of a breakdown
just had to spend a fair bit of cash but up to now worth it.
BUT i have a whining from around the front sprocket (please dont let it be serious) i just lost my job
could anyone give me some advice on what it could be.
just had new clutch and springs and new chain and sprockets fitted but was whining before i had that done but seems little quieter since work was done
as front sprocket nut was loose common fault on fazers i been told the bike has done 58k but always been very well looked after.

thanks

your chain tension could be too tight, try giving the chain more slack

[sirgalahad3]

Yup as solo said. Chain to tight. These bikes need to run a slack chain compared with other bikes. Check your manual and adjust quickly as you will do serious damage

[Andy-Fazer-thou]

OK ill try that thanks

First things first, whip the sprocket cover off & check to see if everything's tight & if there's anything obvious that's making the whining noise.  If you're lucky it may just be something simple like  a Mancunian stuck in there....

I've found a non OE front sprox will whine, are your new sprox OE !

Hi the chain is renthal and steel sprockets i think
i didnt get them from Yamaha

Does your new front sprocket have 'cush' rubbers on it?

If not, that is probably where the whine is coming from.

[Andy-Fazer-thou]

hi again
No i dont think theres any cush washers
not a bad idea though cheers

[Mattsplat]

The GenI sprocket comes with the cush rubbers attached, try one of them.

Before you assume it's the non-OE sprocket, be sure to check that the chain tension is correct.  So many mechanics don't bother to check the specs and assume it's like most bikes ... it isn't, it's needs a lot more slack.

What is the slack needed on one of these as compared to "most bikes"? And is this amount of slack meant to be on the side or centre stand?

[Falcon 269]

40 - 50mm measured on the centrestand, mid-run, tightest part of the chain.

A good rule of thumb is that the chain should just about touch the underside of the swingarm protector when pushed up by hand.

Andy,  Did you get this sorted?  I have the same problem with mine.
