I agree with Joe,there does appear to be the extra 2 guard mount holes on the EX side,but the Image is not real clear maybee they are just well placed scratches.Its real easy Luvpsi,If the base has four mount holes on it its a model 4 if it only has the 2 then its a model 5:)The engine no (assuming the engine is original)could also help in determining the exact model.The cowl on yours is still a very faded avocado,and Deep Brunswick green will be just fine for your handle bars and bracket.
