86 vn750 missfire front cylinder

So far i have changed the front coul pack out with a brand new oem coil pack, brand new NGK 7mm spark plug wires, brand new NGK iridium spark plugs. All of them to hopefully fix the missfire the front cylinder is having at low rpm when im starting to take off from a stand still..once im moving its fine...any thougths as to what it could be?

Have you successfully cleaned all the contacts on the Ignitor connector plug ... ?

The Ignitor is what provides the pulse signal for your spark plug coils.

Remove the plastic right side (body) cover (one screw/bolt) you will see it bolted to the backside (rear) of your battery box, the connector is easily accessible. Carefully remove (6 pin ? & 4 pin ?) connector(s), clean ALL contacts completely on connector plug and receptacles. Contacts should appear as new contacts when completed. . . . take your time.
Contact cleaner, light abrasive material, rubbing alcohol, pencil erasure's (sp ?) ...
you got the idea.....many methods available to clean contacts.
Reconnect connector ....start 'er up !
