Honda-SOHC

Hello there ,After years of restoring two stroke Yamahas (yes I know) I have decided to get a grown ups motorcycle and want a restoration project .Just wondering what you chaps think of this on Ebay ,its the colour and age I want but its been on for ages so I am not expecting a super bargain ,I know that unless you see it in person you cannot give a definative answer but I expect alot of you have looked at the advert and I would appreciate your thoughts,could it be worth a try?I have restored worse but only models I knew alot about.
