It does go away when the clutch is in.
Sometimes when shifting down it feels kind of like the engine wants to drop off the frame. I checked both bolts at the bottom of the frame and they're both there and on tight.

It's not noticeable in 1st to 3rd. 4th from 60-70 is tolerable. Fifth gear feels like a problem. Lots of vibrations and seems like it's straining rather than running smoothly. I'm afraid there might be something wrong with that gear. It is possible to blow just one gear? OR could it maybe be a bad spark plug?

That's the worst case. I did take a look at the tires, rims, and bearings but I'll check them again.
If it goes away when the clutch is in then it means its either engine or load related. The chain/sprocket/countershaft issues for example will show up under load but may disappear when the clutch is pulled. So I'd have a careful look there first. If all seems well there then you'll have to start looking at the engine/transmission and yes you can blow just one gear.
