All buttoned up. Nothing broken or lost. Adjusted cam chain tensioner + valves, installed exhaust and carbs.
Started up 4th or 5th kick. But it did start and idled a bit. Wasn't running great though.
Saw some oil on the engine, not sure if it was leaking or it's the "assembly oil" running down. Heart sank a bit but thought to myself "patience".
Battery was reading 11.6, pretty sure that's why it ran like crap, put it to charge and wiped the oil.
Came back from lunch, battery was reading 12.1 or so, pulled choke, started first kick from stone cold.
Let it run, gradually pushing the choke until it held a good idle. Started smoking from the cylinder fins, smells like the stuff I hosed them down with to try and clean them, looks like it's burning it off eventually it stopped. Checked all the gaskets and no oil. Let it run to temp, took a little video I'll be posting later to show how it runs once warm.
Too early to tell, but at least it does not appear to smoke out the exhaust anymore, only water vapor, and apparently no leaks on the engine that I could see. Pretty happy at this point.
Now need to finish the rest so I can ride it: complete electrical, seat, ...
