Whoever instructed you that doesn't recognize a lot about spark plugs. How are you supposed to go to the shop? Peak HT voltage to initiate spark: 9600 V: 10600 V at magneto: 10.4 %: 9300 V at spark gap-3.1 %: DC component of HT current immediately after striking spark: 53 mA: 52 mA-1.8 %: DC component of HT voltage immediately after striking spark: 910 V: 1160 V at magneto: 27.3 %: 850 V at spark gap-6.6 % What you don't want is both. Today, we can get plug caps from NGK in 5000 (5k) ohm values, which will slowly burn out over time to the 9500 (9.5k) limit over a much longer period. Resistor spark plugs prevent electrical interference that can disrupt car radio reception, two-way radio and cellular phone operation. ?

The higher the resistance, the lower the current. Join Yahoo Answers and get 100 points today. Some bikes such as vintage which are fitted with magnetos don't use resistor caps, as using these could damage the magneto.The high tension lead or leads from the magneto are connected directly by a brass connector at the spark plug---live and learn "Teach". Resistor type spark plugs typically include an "R" in the part number for ease of identification. Has anyone here installed an oil catch can on their vehicle? What do you think of the answers? Hi, Does anyone know of any non-resistor spark plug caps available anywhere. Make sure you have correct resistance for your bike as it affects the ignition. The resistor in question is put into the plug wire connector of atv's, motorcycles and many automobiles. There is a definite lifespan on these components. A rubber "boot" covers each terminal. RFI, as its name suggests, creates static on your radio and interference with other electronic equipment, including the vehicle’s on-board electronic control units (ECUs). The OEM Beru Plugs can be fixed, and if you really like them (i.e. These coils can be retrofitted to the earlier plug cap resistances with improved spark being the result, as the internal parts of the coils did not change. The difference between them is their resistors, the J19LM use a regular resistor while the QJ19LM uses a CDI resistor. The gap, is The “voltage regulator”, It is not intended to be the timing device. Resistor plugs were developed in the 1960s to suppress some of the spark energy, thus lowering RFI to an acceptable level. Also If I listen to earbud headphones I hear electronic interference that directly changes pitch and volume with RPM and at idle.....tick,tick,tick,tick,t,t,t,t, I think with the spark plugs. Karcher 2 and Autoglym lance not working.? Today, we can get plug caps from NGK in 5000 (5k) ohm values, which will slowly burn out over time to the 9500 (9.5k) limit over a much longer period. That can all add up to too much resistance in the circuit and reduce the spark power. How old is it? Fortunately, excessively low resistance is almost never … While I am not familiar with the H1 Cdi system specifically, I would want some resistance in the spark plug circuit. First, by slowing the current flow it reduces EM static that can interfere with electronic ignitions. depends on motorcycle and sparkplug location- on some DOHC engines the long 'resistor' cap is needed just to reach the plug near buried in cam towers, hard to get a cable end and bare wire to attach to plug. The resistances of plugs and wires are designed to achieve optimal spark duration, but the tolerances are rather wide. The earlier large Kaw fours with oem points ignitions were equipped with resistor spark plug caps on solid core plug wires and regular non-R NGKB8ES spark plugs. Am guessing that Kawasaki fitted the oem resistor caps in order to reduce RFI (radio frequency interference), and not to … Still have questions? Triumph Daytona 675 stalls unlike other bikes? Each time the spark jumps across a gap, an electromagnetic field is created that can interfere with radio signals. Furthermore, the use of non-resistor plugs with today's complex computer systems can result in driveability problems, loss of performance and can even cause the computer to store trouble codes.".
