2014 KTM 690 clunking noise when decelerating...?
« on: November 03, 2018, 06:26:20 pm »
Hey guys.

So when laying of throttle or coasting there is a rattling or clunking noise around the left hand side of the engine. I checked the drive chain and the tension seems fine...

When I pull the clutch it disappears,... It sounds like a loose cam/timing chain?

My bike has 27000km on it.


However, I can't hear anything on idle, even when reving in neutral it seems fine..

Any suggestions??

Take off the chain cover and have a good look at your front sprocket.  I had a similar case recently and it turned out the front sprocket was badly worn.  And that was despite replacing both sprockets and chain at the same time.  Poor quality sprocket I presume.

is dit nie die chain wat op swing arm slaan nie.

Die 990 asook 1190/1290 is lief om dit te doen veral as jy throttle toemaak.

Could be the chain as per 'Manic's' reply.
Had the same thing noise on the PitBike that disappeared after I checked the chain tension.

I'm genuinely amazed to see that some ride with a cliplink on a bike, any bike in fact but especially one which sees dirt.
I "demand" a swaged link, nothing less.
Besides, never had the need to take a chain off before replacing it.
What opinions live out there on this?

Looks like is was the chain....when I first checked it I was to stupid the realise the bike should be in neutral as the slack accumulated on top of the swingarm.

Guess it's a reasonable rookie mistake.... ???

Thanks guys!! :)

I must admit that I had not considered that as an option. Glad you sorted it out.
