Hi I’ve got a Lexmoto titan with a 150cc conversion and it was riding fine until I couldn’t go above 50mps on my way to work so I took the front end of the engine off to inspect the valves and piston head to see if there was a problem as I did the conversion, nothing was mechanically wrong with it but i was told by a motorcycle technician that it sounds like it’s misfiring so I start trying to diagnose the issue so I checked if there was spark and there was a consistent spark which lasted for a straight 5 seconds and I didn’t quite understand what could cause that so I removed the ignition coil and inspected the connections and there was water ingress into the coil pack from the wire that goes into it from the spark plug so I cut the HD lead and crews the coil back on and tried it again and there was no spark but all the connections were clean and there was 100% a good connection from the coil pack to the HD lead so I’m thinking it’s further up the line
