Thought I would just share a story about my GS650 Katana.
I bought it with receipts to show that it had recently had a lot of valve work etc done at a Suzuki dealership.
As a matter of course I checked the compression and found that number 2 was 3/4 of what the other 3 cylinders were.
I immediately thought expensive rebores, rings etc.
Anyway I checked the valve clearances and found that all 4 cylinders were tight on the inlets and on cylinder 2 I had to drop from a 2.70 shim to a 2.60X.
A new compression check revealed that all 4 cylinders are reading high and almost the same!
All I can say is 1st thing to do is check those clearances!
