Hi Folks, I am in the process of doing a top end on my 2003 125. Considering my experience with this sort of thing its been going well. Hit a snag though once I got the whole thing back together and tried to start it. Nothing happened. I shouldn't say nothing, I had the fuel tank up and I was doing a test start so I could see into the engine. There seemed to be a large spark come out of each battery connection. Not sure what this means. There was no turn over of the engine and not much else happened. Lights, indicators etc work fine. Fuses are fine also. Subsequently have not got spark and have been scratching my head and going through the possibilities. New spark plug still nothing. I may have narrowed down to the HT lead (picture attached). I get no reading from the lead that connects to the spark plug into the earthed connection (nor any other for that matter). There was no electrical problem prior to work commencing so not sure how/why something went wrong. I am thinking I may have bent the lead back that my have dislodged/broke a connection? Does this sound feasible. Any advice appreciated. aaron.
