1976 CB750 HEI Ignition Test w/GM coils

This is a test of my HEI ignition on my 1976 Honda CB750.  I can't take credit for this as I am not the creator.  Lou is the genius behind this for more details check out his site http://home.comcast.net/~loudgpz/GPZweb/Ignition/CBheiModCavCoil.html or hondacb650.com.

In a nut shell I took some reluctors from my old honda cb650 made a custom timing plate for them to sit on and turned down a small chunk of the rotor to make it fit on the advance of the older model cb750.  The rotor from the cb650 is about 1/16" too meaty so I very carefully ground it down.  Since I am using the stock advance and the reluctor sensor and rotor line up a the F mark I am hoping timing will not be an issue.

The biggest challenge is in mounting the coils.  They are under the battery box.
