Do you guys know what that is in cylinder 3 and if it's normal or not? It looks like oil to me and the spark plug was all oily aswell and bike wont start

First thing, get a compression test on the cylinders.

If it is oil then it could be worn bore/rings/piston. A compression test would rule a lot of that out.

It could also be the o-rings around the spark plug tunnel or the seals between the rocker cover and spark plug funnels. Is there oil dripping from beneath the exhaust port #3?

Well the reason it was not running was because fuel pump was not working.. but i took the head off aswell and it looks like theres surface rust on cyl3?? Im sure it was running on all 4 before it stalled so how the heck is there rust in there... unless it has started to rust when the bike stood for 5 days before i took the head off.. anyway here is a pic

had my friend over and he looked at the head etc and said it was fine and told me to just put everythin together after swapping the head gasket, well not soon after there's more problems................................................... Just when i'm about to tighten it all up and finnish the work the damn bolt holding the camshaft in place decides to snap!! my face went from to in a millisecond

now i'm left with half of the bolt in the camshaft cover thing and I have no damn clue how I should extract it so any ideas would be real helpful... (i blame the torque wrench for being a pile of crap)
