Lucky you on finding this bike. As to your question on the need to use premium gas in your bike. A Triumph T100 that I restored had a compression ratio of 9:1 and I ran it on today's premium. If I really loaded it, it would still ping on occasion, so I made damned sure I never used regular gas. Seeing as your RS is 9.5:1, I would not even contemplate using regular gas. You have too nice of a bike to go for the less expensive grade of fuel. Put the additional cost of premium fuel as one of the expenses that come with owning a premium bike.
