NGK Resistor plug caps.

[Detonation]

Anyone had problems with the resistor ones before.

My bike has struggled to start the last few days and I've just clicked it started when I fitted the new resistor caps.

My batterys one charge at the moment so I can't run out and swap the caps back and try it just yet so would be good to hear if others have had problems?

I've just read that if you have 20 year old coils which will be weaker than when it rolled out the shop then resistor caps may offer too much of a challenge for the coils.
