I like to do my own minor maintenance. Is the original battery acid or maintenance free? How do you get the spark plugs out? Do you have to remove or lift the gas tank? I would like to install iridium spark plugs.I also wondered about periodic changing coolant and brake fluid, air filter change to a K& N filter,oil and oil filter change and belt or tube tire problems? Will the electrical system handle a light bar up front? Please respond to forum and to my E-mail. Thank You.
