is there a break in period?
It should, and 'yes'. The manufacture should specify how long that is.

i read it may get better performance after 150 miles on it???
Yes, after it is broken in.

do i vary the speeds for few tanks?
Yes, speed, and rpm.
when do i change oil?
That should also be specified in the manual or instructions that came with it.

yes, i am a newbie...
