I bought a R400 from a coworker a few weeks ago. It has been in storage for 20 years but is in very good shape. The tires were in bad shape so I slapped a couple of used one I had and rode it a little. He even had the original owners manual for it. I'm not sure what to do with it or if I should even trust the aluminum fork. I'll post some pictures if it if anyone is interested in them.
