After 92000 KM I had to re-check the compression due loss of power and overheating when revved.

Dry Cylinder Compression in Bar
------------------------------

1 -----> 6
2 -----> 5
3 -----> 4
4 -----> 5

Wet Cylinder Compression
------------------------

1 -----> 8
2 -----> 7.5
3 -----> 7
4 -----> 7


From compression reading, I am guessing I would have to replace rings?

- What could be the reason for huge drop in compression for some 20K kms? (see my first post for original dry compression)
- I don't see any smoke in tail pipe nor I am loosing oil.
- I have repeated the tests twice between 1000 kms and results are same as above.
