Cannondaleriders

Looking at a 03 Cannibal. How do I tell if there have been any updates on the engine such as the ATK updates?

Any suggestions on what to look for on the 03 Cannibal, problematic areas of concern etc?

Thanks

Just assume that nothing is done is the best policy. If your lucky maybe the crank plate will have a stud kit. ALL cannons should get a complete teardown before using anyway.
