Not an expert, take my thoughts with a grain of salt, but.
You would be better off lowering compression and upping boost than increasing compression and maintaining the same boost. Bikes in general already have pretty high compression ratios, I wanna say 12.5:1 is just about standard, my last turbo car had 8:1 compression, allowing me to up the boost and adding more power than just adding compression.
I would also question your fuel situation, I'm guessing that buy a 2nd fuel rail you mean the injectors are squirting into the head like the stock ones. instead they squirt into air hose from the airbox. The fuel doesnt vaporize as well the further up the air stream you go, instead it clumps into larger droplets and burns slower in the cylinder, causing preignition, upgrading the compression you will need a much better fuel system, possibly a larger dual stage injector in the stock location.
Anyway, to sum it up, leave it alone, upping compression on a blown bike will do nothing except cause detonation and broken engines. Save your money and buy a chrome spike kit or something instead
