Are you saying it needs one full point more compression than the 117's 9.9:1? Or one full point more than the 10.6:1 from domed pistons being added to the 117?
Yes, as Joe said, 11.6:1 even as high as 12:1
I have done it and made 149hp SAE with a 120R using the same cam @12:1, hand ported CVO 110 heads. Cranks less than the stock CVO 110 motorcycle.
A cam like Woods 9B, Tman 662-1 or 662-2 with compression adjusted for intake close will make more aggregate torque (what you feel seat of pants) but the 266E will be the HP leader by a small margin all else equal. Pipe comes into play shaping the curve.

You have only scratched the surface. That curve has all the looks of a jacked up tune and or blowing through the clutch. The lines should be smoother.
You like it now, get it fixed and it will be better. No offence intended just constructive.. trying to help.
The graph, are those corrected numbers? No indication on the graph so they are not likely corrected. Could lower or raise the numbers overall.
