On the DOHC 450's and 500's , the flywheels are different...The 500 is a "stroker" 450 in that respect (Assuming you mean the actual "throw" flywheels of the crankshaft)... The SOHC "Hawk/CM" were 400cc or 450 cc bikes...They did not come in a 500 version..... Completely different crankshaft/flywheels from the DOHC engines....

He may be talking about the alternator rotor??

Who knows.......

At any rate, nothing is interchangeable between those models (except for 450/500T rotors), totally different engines.......

Not only that, but I think the CM's were CDI ignition (after 81 or 82), no????
