Cost depends mostly on use and age of components as every part is a wear and tuning item, even the frame. I would say expect about $150-300 in just chassis maintenance, and $100-700 a year in engine maintenance and oil/fuel. Again all depends on how often you drive it and if a part breaks, worn out, or bottom end maintenance is due on the engine. CR80/CR85 Complete Engine Rebuild Kit. CR80 1986-2002 CR85 2003-2004.
