Knocking from chain, worse when turning
« on: 15 May 2017, 09:37:21 am »
So the bike has developed a knocking-"feel" from the chain, and it gets worse whenever I turn hard left/right in slow speeds.


Could it be anything other than the need for a new chain?

Yep you've got a tight spot, if you can hear it while riding the chain has had it.

it could also be that your chain is too slacked, try giving it a good clean & adjust it properly as well as lubing before going down the route of getting new chain & Sprockets.

I know it's not too loose, but perhaps I tightened it too much...

Check the free-play is within the specified tolerance. (can't remember what it is off the top of my head).

Just looking at my owners manual and it states "Normal slack is approximately 30 ~ 45 mm."

If when leaning left check front sprocket hasn't come loose

Last time I adjusted the chain I didn't do it properly... I just picked a spot and began adjusting to roughly 30-40mm.
I now found the tightest part of the chain and measured, it was 20mm :O

Adjusted it to 35mm, sound is gone :)

But there probably is a tight spot somewhere along the chain, and one o-ring on the master link has been damaged, so it's leaking red stuff from it :/

Probably due for a new chain anyway.

Buy a D.I.D. X Ring chain & sprocket kit, they're very good, tried and tested, and if looked after will last a very long time.
