Thanks a million guys for all your advice.
Yesterday I checked the rear of the inlet manifold and cam across " SO" so there ya go. She seems to be a 105. To be honest I wouldnt have known the difference in power. As a 105 shes quick enough for me.. Even if I had known when I looked at her she wasnt a 130 I still would have bought her. She is mint inside and out and sitting on 28 thousand miles..Spent most of her life in the Isle of Wight as far as I know. Only rust was the battery tray which has been replaced. She has the MX75 box and the full leather wing back interior.. So that little sticker on the inlet pipe duped me lol.
