Come across a old 1995 CR250 motocross bike that's sat outside covered in a sheet and fancy having a go at doing it up but not 100% sure what I'm looking at. It looks complete and apparently runs. It's recently had some work done on the engine but not sure exactly what. The bike looks pretty rough but is complete. The engine has been painted black and the paint is starting to flake off. In a nutshell what should I look for and what are they worth in rough but running condition. How much do they go for in clean condition and can you get hold of parts.
