If you have the cap in your hand, it is simple enough to put a VOM meter on it, and see what the resistance measures.

I looked at a few of my caps. The resistance is shown under the part number.

For example, the LB05F caps have printed “5KΩ” under the “LB05F”.
“053” is printed at the base, but that has nothing to do with the resistance.

Your LZFH caps don’t have any printed resistance.
As others have said, your LZFH caps are non-resistor.
BAS (Bike Acquisition Syndrome) - too many bikes but have room for more

Thanks ! that's what I finally concluded, non resistor caps, not sure why hvc cycle has them listed as resistor type?,, ohh well thanks guys sorry for such a long in depth discussion on something so minor,,,,,

A colder plug will foul quicker, a hotter plug can 'burn' off deposits better. Put non-resistor caps on all the plugs, check and compare resistances to each plug wire and coil to be sure they are all very close to each other. Next check compression, if OK, check the oil injection lines to that cylinder, mainly of the check valves to see if they are stuck open, thus over oiling. Basically, you are too rich, weak ignition, too much oil, or bad seal(s). It can be tough trying to trace down some problems.....
