Bought a 1990 CR250 as a project bike. The bike had been sitting for a long time. I bought the bike for $50.00. The first thing I noticed that was wrong with the bike was that the fork seals were blown. I ordered new seals, and have yet to replace them. After further investigation, I noticed a tiny spot of rust on the fork sliders. Obviously this is the reason why the seals are blown. Is there a way to repair the slider? Would the slider itself need to be replaced? Pardon my spelling, but would hard anodizing fix the situation? I may have a simular problem with the rear shock. Is the Rod replaceable, or do I need a new rear shock?
