Hi, I´m UK as well, my bike was imported in 1997 but year of manufacture´s 1984 on the log book, trouble is my bikes, 83 & 84 both have the 82 type air-filters, one each side and both have the 82 type discs of non curved grooves??? My 84´s also missing the Indicator Angle Sensor, not sure if it´s been removed in the past or if it was simply never installed?
