I cannot find the gl650's fuel requirement anywhere in my books. Can someone tell me what octane it should be?

I'm with Marshall on this.Even though we have a different blend of fuel over here and I use just straight economy brand unleaded I still add a bit of any cheap fuel treatment from the supermarket.

Don't pay premium prices for Brand names as it's all pretty much the same UCL(Upper Cylinder Lubricant) no matter what the sales hype says.It also helps keep the carbs clean/lubed and also as per above stabilizes the fuel if you have to leave the bike unused for any length of time.

My 10 penn'th.
