EDIT: I now agree with Al, see below

Here are the relevant rules

<R23> Individual COMPONENTS or MECHANISMS retrieved from previous ROBOTS and used on 2009 ROBOTS must have their undepreciated cost included in the 2009 robot cost accounting, and applied to the overall cost limits.

Ok, so the motor's depreciated cost must be accounted for, no problem.

<R32> COTS ITEMS from ROBOTS entered in previous FIRST competitions or COTS MECHANISMS that are no longer commercially available may be used under the following conditions:
A. The item must be unmodified, and still in its original condition as delivered from the VENDOR, and
B. The item must not be a part custom made for the FIRST competition and provided in the Kit Of Parts for a previous FIRST Robotics Competition (e.g. 2006 FRC transmissions, custom-made motor couplers, custom sensor strips, 2006 IFI CMUcam II modules, etc. are not permitted), and
C. The item must satisfy ALL of the rules associated with materials/parts use for the 2009 FIRST Robotics Competition)

The CIM motor is a COTS part and is not legally allowed to be modified from it's original condition. I would argue that crimp connectors and trimming the wire leads while against the exact letter of this rule are well within the intent (obviously the only official judge of intent is the GDC themselves).

<R51> Motors specifically permitted on 2009 FRC ROBOTS include:
...
D. One or two additional 2-1/2” CIM motors (part #FR801-001 and/or M4-R0062-12) in addition to those provided in the Kit Of Parts. This means that up to four, and no more, 2-1/2” CIM motors can be used on the ROBOT.

This rule makes no specifications as to the source of the additional CIM motors that you are allowed to use.

Unless I missed a rule limiting these motors to spares, it seems to me like it would be legal to use them on your 2009 robot.

EDIT: Missed <R50> somehow. I am now in agreement with Al's post.
