Spark plug resistor cap replacementSpark plug resistor cap replacementI have 4 ohm XS650 coils (and e-igintion) that have been great so far. I need to replace my spark plug caps, the rubber boots have swollen and fallen off, either from oil absorption, heat, or a mixture of the two.
The plugs I were using were 5 ohm NGK's without any issue. Is it proper form to match the caps with the coils output? Google can't seem to find anything relating to "4 ohm spark plug resistor cap". Eager to learn a little more about this. Current restoration: 1962 CB77

Not related.Plug cap resistance isn't related to your coils. The lowest resistance of the caps needed so as not to give your electronic ignition trouble is all you need. The 5K ohm caps you have from NGK are the lowest resistor caps you'll find and they beat the crap out of any factory caps for reliability. If you replace the wires go with about 4ft of solid 5 strand wire from the dealer or a 6ft length from Den Kirk. Automotive resistor wire will give you all sorts of problems. Over heating/hard spots in the sheathing that protect your factory wires are a good sighn that you need new wires. If you remove the sheathing and the wire itself is still plyable with no bad spots in the insulation then you can trim off about 3/8 of an inch from both ends and re-use it.
CB77.Just changed the wires on my CB77 stock coils. They are held in by an aluminum nut and tin collar with a rubber compresion keeper. Not sure if the wires from an XS650 coil can be changed.
The 6ft length of wire is reffered to as solid core wire but I'm not sure of the part number. Number of strands is actually not important as the length I purchased from my honda dealer last time has quite a few more strand. Just purchased two 5 ohm LD05F caps. Found this handy guide.
