Rear sprocket & chain chatter

Just bought a new SD which now has 650 Km on the clock. Still running in. 1st service at 1000 Km.

All my experience has been on big fours - still learning the torque delivery of the SD. I wonder if anyone can advise please?

I live in Switzerland so most of these 650 Km's have been done on very twisty roads where apex speed is often as low as 30 mph in 2nd. Very careful not to over-load a new engine when winding on from around 1500 rpm, but even so, under moderate acceleration there seems to be excessive sprocket & chain noise. Compared to a four in the same gear with similar throttle input & revs I wouldn't expect it.

I have to be surprisingly gentle during initial wind on to prevent it. Back wheel is bang in-line & chain tensioned correctly without tight spots - so mystified.

Is it the dipstick riding it? Is this normal for an SD so ignore it? Is it because I'm running in? Or will the dealer wave a magic wand over it during its 1st service?

I'd appreciate your views....

Cheers

it does sound like the chain is too loosse. it does need to be tensioned correctly and lubed (obviously) also with a twin or especially a single if yer going slow on a high gear then the engine pulses aren't far enough apart and make the cahain chatter if it is a bit on the loose side
imho i'd rather have a slightly loose chain than a slightly tight one (ooh err missus!)

When I first got to a twin I had the same issue, my aprilia RSV did the same thing. As Cowelly explained all twins do this more ore less, just use a lower gear and more revs.

Going from a 38 to a 40 tooth sprocket on the rear might help. Higher revs for any given speed. But I'd get more used to it before deciding.
