Reply To: Crankcase leak? – GV250 2018
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),Ā Hyosung uses factory “bond” to join the crankcase halves together,Ā otherwise some people have been rebuilding engines with some gasket card and cut it to fitĀ or they use engine bonds used by cars to bind the cases togetherĀ , theĀ service manual for your bike (at manualslib) should mention the type of bond used.
