Bike Model = : GV250 2018
I have recently baught a gv250 2018 that had some leaks (more like sweat) but otherwise it was good and at a good price point so I figured I could replace the gaskets and all will be good.
So I cleaned the engine with some degreaser just to see what gasket leaks so I know what to replace. Other than the obvious valve cover gasket I have noticed the crankcase itself is a split one and it also leaks a bit at the top and a bit from the front.
Is it a common thing? I havent found a crankcase gasket to purchase anywhere

That’s new , if you ever do valve clearances next time, remove the cam shafts and tighten the long 4x engine cylinder bolts which holds the cylinder head & piston jug together , but this may help squash the gaskets a tiny bit (a tiny bit) , but worth checking next time.
That is my suspicion , it doesnt seem to come from the top of the valve covers but near the piston area, so could be piston jug gasket rather than engine crank-half gasket (bond), Hyosung uses factory “bond” to join the crankcase halves together, otherwise some people have been rebuilding engines with some gasket card and cut it to fit or they use engine bonds used by cars to bind the cases together , the service manual for your bike (at manualslib) should mention the type of bond used.

i have sweats from the val e cover gasket I will replace it once it gets delivered but I thought about leaving this as it is.. it doesnt look too bad but It does look like a lot of hussle just for this tiny spec of oil sweat
