Debatable thread
I was reading a workshop manual the other day of another type of bike engine.
The recommended spark plug in bold, insisted the plug be a resistor type.
What this means is, when buying a spark plug by it's number, in that number it has to have the letter "R" which stands for Resistor.
I then rang to order the replacement parts and was again reminded that it MUST have the resistor type spark plug or it will blow the CDI again.
I asked why !
Can someome clarify the following reason;
I was told the voltage on the plug lead can infact jump back into the CDI. A resistor spark plug stops this from occuring.
I was wondering due to the number of posts about CDI's having been fizzled, replaced and fizzled again, perhaps the spark plug needs to be the resistor type on our HT's ?
So for example if we use NGK BSHS, then it might have to changed to;
NGK BR6HS ?
Google search explains somewhat here. Would this apply to the HT CDI ?
