Will most surely post a photo of that later as well. Sad to hear they look worn... Can they be fixed or do I need to look for replacement?

I'm not an expert, but those cam lobes (correct name?) looks quite bad to me.
Are we talking something that can be repaired, or replacements?
If a repair is half-bad solution, then I'll most likely prefer looking for some replacements.

Annoying they look so bad, but then again... better find it now, before something breaks completely.

Camshaft and rockers are quite expensive...
350$ for a new cam shaft and 120$ a piece for rocker arms. So new cam shaft and rocker arms would set me back almost 600$...

Hope I can find some used on ebay that are still OK.

Are cam shafts and rockers compatible across all years?

Those rockers look as bad as mine did when I replaced them, I think a pair was $94 but your experience may be different. I think that you should take the camshaft out and examine the bearing surfaces as well. This engine is well known for top end lubrication issues (which is why you should keep the idle speed at ~1000 rpm or better still start it and just drive off). If the bearing surfaces are shot the manual glibly states that the head should be replaced and that is hugely expensive at ~ $740.
Hopefully you can live with the bearing surfaces and perhaps just polish the cam with some fine emery.

Good luck

tl;dr don't invest in new rockers if the head is shot.

Can you let us know how many miles are on your bike, if you routinely kept the idle speed up, ran it low on oil or let it idle on the side stand frequently? The information may be useful to others. Thanks. Oops. Your post came while I was typing mine. Disregard.

Hope you will be able to find good used parts. Sadly Suzuki is very proud of their replacement parts. :'( Let us know what happens.

The rockers must be replaced though; expect $110

Cam repair... I ask a dealer I suppose?

It costs no more to repair to stock spec's as it does to repair to Performance spec's.
This is what I do.
$299 with your cam.
It takes a few weeks.
PM me for shipping details if you are interested.
