Hi to one and all,
I am looking for some advice and direction to try to cure a problem.
I have a 1974 CB250 K4. Last time out it lost its spark to left side plug. The right side is still working fine (I rode 40 miles home on one cylinder). The bike will start but runs only on r/h cylinder.
I have replaced both coils, condenser, plug cap. The plug sparks fine if I put it in the opposite side and test. The points look fine, no pitting or burning (I have re-dressed them with a bit of wet and dry paper and gapped them).
But still no spark in the left side.
Does anybody have any advice as to where to go from here?
Thanks
