Would the lower primary resistance of the R1 coil cap suggest that a different spark plug would be needed ? Or is the lower resistance a result of the smaller coil compared to the 850 coil ? Or summat else ? [img]style_emoticons/<#EMO_DIR#>/unsure.gif[/img]
Just thinking that if it's because the coil is smaller then the lower resistance reading wouldn't matter.<!--QuoteEnd--><!--QuoteEEnd-->
So far I understand.
I think that the lower resistance will draw a bigger current. Wich could give a bigger spark. But this could also reduce the lifetime of the coil.
I think that the best is to find coils with the same primary winding resistance as original.
If a different spark plug is needed? I do not know. A different outer geometry of the spark plugs can be used to make the coils/caps fit.
