Double-check the engine oil level. Low level of oil causes friction and induces heat build-up which can cause vibrations in the engine.
Is the oil filter seated properly?
Finally, did you clean the air filter too? Maybe that isn't set properly?
Since you've checked the chain tension and that is okay, your problem seems centred around the engine oil. I'd just drain the oil once again and replace it with oil bought from a different vendor, of the right grade. You never know, you maybe been sold spurious oil. Change the oil filter too.
And monitor that oil leak, it may just be spillage run-off but it pays to be cautious.
