Hey guys, this is my first post. Im buying my first bike. My sister boyfriend tells me that he has a 1990 Honda XR 250 that hes willing to sell. He says its been sitting under his basment stairs (Indoors) for 3 years. I want to know are there any problems that I should know about with this year and model of bike, and if you think that it sitting for 3 years will affect anything. Ill do some minor things to it like change the gas ( if theres any in it ) change the oil, change the spark plug etc. Also are there any performance parts available for a bike this old?
