i have a rebuilt engine right now that runs.. but i compression test shows that my front rotor has low compression in it. is it still safe to drive it? will i mess up my rotor sooner or later? and i do you think its possible to fix it? and how much would that be? thanks for your help

It's a bit low, but still within spec.  I would wait till you hit the 10,000 mile mark to see if it comes up a bit.  Mazda factory spec allows 20psi of variance between front/rear rotors, and you're right at that spec right now.

Did you do a proper break-in procedure?
Does Hayes offer a warranty on our engine?  If they do, how much longer do you have before it runs out?  12k miles?

they do offer a warranty but only off the original buyer and its gone through two owners already.
the warranty is 24,000 miles

yea
yea it also screws up your oxygen sensor and gets the fire department to come to your house.
It works great on OLD engines with LOTS OF CARBON as a LAST RESORT.
It is not a fix all end all.
It can't hurt though if you have the money for new plugs/oxygen sensor...

hmmm...
someone correct me if I am wrong...but
the compression of any rotor cannot be changed, you are within spec so I wouldn't complain to much.
The thing with these engines, is that if you have a seal leaking out into or out of your engine, that can only be replaced in a re-build, same goes with coolant seals...
When that engine was rebuilt, chances are it was the front rotor that went out (just speculation) and that they re-used the same rotor/rotor housing. A lot of re-building places do this...but if it is a HAYES rebuild, your within spec (which you are) and you are not burning or leaking coolant/oil then I wouldn't worry about it.
