Q) What Spark Plugs do you suggest?  A) I use NGK B8ES.  We suggest you check with your motorcycle's manual for the recommended spark plugs for your bike.

Q) Should I use resistor or non-resistor plugs and caps? A)  Your answer in this blog post

Q) Are iridium spark plugs OK? A) There is no harm in using iridium spark plugs like NGK BPR7EIX; with these plugs we recommend non-resistor caps like NGK LZFH.

Q) Does the Dual Lead Igntion Coil 6 or 12-Volt (IGC-2012, IGC-2006) have positive and negative for wiring?  A) They do not have negative or positive you can wire them either way.

Q) The ignition warning light assimilator won't go out on my Norton Commando?  A) The warning light assimilator is not compatible with any regulator rectifier unit that are available.  They were designed to work with the zenor diode rectifier set-up from Lucas.
