Sprocket cam balance weights?

Hi,
Because my original sprocket was broken I bought a new one. Luckely it was availible.
Can someone tell me what the function is of the metal blocks mounted to the original sprocket? I assume that these are for balancing?

The original large sprocket was indended to damp out torqe fluctuations and give the cam chain an easier ride. It acted like a small flywheel but was later deemed unnecessary.

Hi G,
Thank you for this info! So installing the new sprocket without those wheight is no problem?

You'll be fine, providing you have the correct sprocket for your bike. The dream sprocket has a different advance/retard mechanism from CB and CL.

Thank you all for the help. Unfortunately the sprocket was not in stock anymore at CSMS.
So I bought one on eBay, I received it yesterday and I installed it. My question, is there some rule for how to mount this sprocket? at this moment I can shift it a bit to the right and to the left.
I can secure it with the bold in the camshaft at the right but what is the exact position of the sprocket?
Thanks in advance for the help.
