on such an old bike several eletricl things might be wrong. Check the sparkplugg for a big fat blue spark, if you got that it should fire, unless the carbs are foulded. Pull in decomp level turn engine by kick starter slowly past tdc point by an inc, let decomp level out, raise you leg and kick starter to start point, and jump on it (engine wont generate spark at slow rev so hit it rappid) thats it. now hang on to the bike as it wheelies out of the parkng lot :-)
