Is ther some thing to do on the havy vibrations during the printing???

If the wavy lines are caused by vibrations, you can reduce the acceleration from 5000 to 3000 and it won't affect print time much:

Do those pictures agree with your "wavy vibrations"?

Why do you want to clean the bowden? You can take it off but be careful - it's easy to damage. If there are pieces of PLA inside, just let them go through and melt in the head.

UM1 or UM2?

On the head you have to reduce the pressure on the bowden by unscrewing/taking apart the head a little bit - to reduce the pressure. Then remove the little red or blue clip and push down on the outer ring and slide up the tube. The gray ring that holds the bowden in has 4 metal blades. If you aren't careful you will scrape the bowden and when you put it back in it won't stay in very well. Don't pull up very hard. This instructions were written for UM1 and UM2.

I've never removed the bowden on the other end.

You might also consider reducing the xy-jerk setting, if the issue is just mechanical vibration of the whole printer during printing fast, short infill sections where the head changes direction lots in a short amount of time.
