Even stock motors overdraw AA-sized IMR's though. They provide the right voltage, but they cannot supply the current (amperage) demands of even stock motors at stock voltage. Raising the voltage raises the current draw, and stock and aftermarket motors all draw more current than AA-size IMR's are rated to supply.
At best, it'll work for a while before burning up your switches and/or battery tray (which isn't designed to supply more current either). At worst, they'll blow out and melt/ignite your blaster.

I've run my stock motor stryfe on 3 efest Imrs for quite a while now with no problems. Sure its not ideal but its a lot better than stock. I'm sure my 3 imrs will burn the stock motors out faster than most would like but mine have lasted a while now, and I'm sure stepping down to 2 imrs would increase motor life, and will still be much better than stock aa batteries
The risk isn't just burning out the motors, it's burning out the batteries. If they burn out, they can burn a hole in the blaster or ignite it wholesale.

Sorry to join this conversation so late. As Arctic Hunter eluded to, the problem with IMRs is the amount of instantaneous current they can supply. Beefy 130s and most 180 motors want to draw much more current than IMRs can provide. I suggest going straight to LiPo if you're using anything larger than a 130.
Related to that, the second factor is the milliamp hours rating of your IMRs. Generally, but not always, an IMR with a higher mAh rating can provide more current at any given moment. Cheap IMRs produce about 5 amps, and many can produce 10 amps for short periods of time. If you're sticking with IMRs, I suggest looking for batteries with a minimum of 2000 mAh. Anything less than that will be disappointing.
The third factor with IMRs is the voltage. Fully charged, they produce 4.2 volts for a short period of time. Under load, the voltage steadily decreases from 3.9 to 3.0 volts, and the current remains relatively constant. But as Meaker VI mentioned, there are some dangers associated with unprotected IMRs. If the voltage falls below 3.0 volts, even for a moment, it starts a catastrophic exothermic chain reaction. Sometimes it can cause a fire. For those reasons, don't buy unprotected IMRs.
