Sprocket and Chain advice needed

[Jamieg285]

Been having some really odd noises coming from down on the left side.  Having read lots of posts, I have pulled the sprocket cover (found a nut  ) and checked the sprocket. There is ever so slight indication of 'shark tooth', so I am assuming this is shot and needs replacing. 


The rear sprocket looks good and the chain looks to have lots of adjustment left, based on there being more alignment lines behind the axle and in the front of it.  That said, I followed the Haynes guide and measured 10 links.  It measured 154mm, which is 3mm more than the suggested maximum stretch, so I am assuming that is shot too, and I really should be looking to replace all three.


I think I read somewhere that the genuine Yamaha front sprocket is sufficiently superior to aftermarket ones to make it a good purchase, but what about the rear - does it make much difference what make/type you get?


I'm also looking for advice on what chain to get.  I am an all weather Mon-Fri commuter, so want something that will last.  I'm not bothered about bling and cost isn't too much of an issue. I don't mind paying more for a decent product.


What can you tell me?  Thanks in advance...

I always get the D.I.D. X Ring (gold) heavy duty chain and sprocket kit, i got 4 years out of the last one until our obscene weather got the better of it and it started getting sticky links.
But i like the fact that it hardly needs adjustment at all, it's a really solid chain, just keep it cleaned and lubed regularly and it'll serve you well.

as above. the chain might look ok but could be stretched. get the whole kit. you wont believe the difference

Always good practice to replace chain & sprockets together. IMO Yamaha front sprocket far superior to after market as it has built in "cushioning" to reduce noise/vibration. Also replace front sprocket nut & lockwasher using the modified 12mm nut-see chain & sprocket saga posts! :eek

I doubt if i adjusted my last chain by a few mm max, the better quality chain you get the less messing about with it.


Ignore the price, you can find cheaper      http://www.yamahamotorcyclespares.co.uk/spares/partImage.asp?GPN=3502725&uid
