Yes agreed - I have an 82 seca as well (550) - but I have had a devil of a time identifying it - it has chrome turn signals, a Xj550 style tail end, mag wheels, chrome around the round headlight, and a gold and metallic YICS in line 4.... Nothing I have found on line is similar. The bike is giving me running troubles, stalls at idle speed. Replaced coils and plug caps - but still is a problem - it runs a little rough as well. Carbs and vacs are great, and just put new rubber manifolds on it - but still problems
