So I was out riding today and just sorta ended up at the airport... small (SMALL) town airstrip... I went inside and asked the guy if he had some High Octane fuel for me. He said, yeah but it's only for planes, he can't sell it to street vehicles... he then looked outside and saw my bike and that it was a BMW K1200R and said, "hey no one's here I'll open the gate, drive on it." So I drove onto the tarmac and up to the pump. I asked him what it came out to be and he said about 105RON but there was a slight glitch... it was leaded and since I still had my stock Exhaust with the cat I realized I couldn't fill up... what a disappointment! So anyway... any of you guys without a cat ever try this kind of fuel? I was so excited to feel it, it's got me thinking real hard about losing my stock can.
