wild speculative suggestion ...
plug not earthing so no spark.?? thinking it has been stood for a long time, thin layer of dust or corrosion ??I had a similar problem on a XV750 stood for 12 months in a garage. bought one of those colourtunes with a mirror on top to see if the fuel mixture was yellow or blue - fact was it wasnt anything because it wasnt firing. after a air filter and flow check, fuel check, carb check, timing check, HT circuit check , it ended up being a clean of the cylinder top around where the plug earths. voila
