Title: Pin hole leaking oil on right hand crankcase
Post by: Stuh on 30 Sep, 2025, 19:19
Just changed the clutch cable and so the right hand engine cover removed and there is a tiny hole in the crank case that weeps a small amount of oil when on centre stand didn't seem to on side stand leaning away. Is this pin hole supposed to be there?  video too large to post.
Only had the bike 4 days so new to this. Thanks in advance

Yes, that hole is supposed to be there. It's purpose is to allow oil, which has been blown out through the engine breather, back into the crankcase.
