So I had recently acquired a 2003 Honda CB900 from a private sale (in the a very clean condition for it's age I might add =P).
At the moment, I am using 95 since the previous owner used it as well. However, I would like to make the switch to 91 just to save a few extra dollars.
The only thing stopping me is that I'm not too sure if it's a good idea to mix 95 and 91 in the same tank. Is this a good idea?
Additionally, does anyone have links to resources where I can learn more about the mechanics behind motorcycles?
