My BA 2002 Beast has almost 20,000 miles. I have lubed the chain, changed the oil & filter every 4000 miles, changed the spark plugs every 4 to 5000 miles, gone through two sets of brake pads front and rear, changed front and rear tires once, installed new battery once, and installed a new speedometer cable within the last 200 miles (Maybe I should have lubed the old one). She has D&D pipes with a jet kit and I ride her like I stole her. She runs like a raped ape. She doesn't care if it is raining or sunny. She likes to be ridden. I keep checking the Valves and believe one adjustment will work for me.
