in my years of Modifying bikes (mostly 2 strokes) i discovered most bikes gain very little benefit from increasing compression.... oddly enough as v-8 engines really do gain alot.... I believe that is due to mutable cylinders...
...I think there is more to be gained in a properly tuned carburetor than raising compression, or even changing the cams is better than compression
simply because you put so much more stress on the parts when increasing compression for very little gain...
Larger carburetors and better cams would be my suggestion for motor hop up on a ninja.... not increased compression...
.... my 2 cents worth !
