More brain picking

Seeing as my EXC-f is in itty bitty peices a good friend has loaned me a 2007 300 exc to do the last round of TBEC`c championship on (saves a whole years of racing going to poo) , so ive done some basics to the bike to get it race ready but its done 160 hrs 3000 ish miles on an un-touched from new engine .

I did a trial on it at canada heights to get a feel for it and all seems dandy enough (lurvely mellow bike) i just wanted to know roughly what kind of compression a healthy one would be putting out ??

Any other hints tips for this bike would be helpfull too , thanks
