I've noticed that I'm changing plugs about every 5000 k's as my bike is developing a low speed miss and I'm not sure why. When the motor gets above 1500 RPM the miss disapears and it does not show under load. I've read that plug lead caps have a resister inbuilt and that the resistance should be around 5000 ohms when on a multi meter, I've tested two and they both are within spec but the other two won't read on the multi meter so I'm guessing that the plugs are failing due to this. I've priced replacement caps and they are about $27, what I'd rather do is replace the resistors but am not sure where they could be sourced.
I am also thinking that I could just cover them with aluminium foil in the same way that you can cover fuses in an emergency to get you to the nearest supplier. I'm not sure if this could damage any of the electronics though.
Anyone able to advise?
