Lead shouldn't react with titanium. The reason you don't want to use it in cars is lead will cover the platinum catalyst in catalitic converters. I don't think it even reacts with the platinum... just covers it.
But hey... chemestry was a long time ago so I could be wrong.
I don't think it's the ti valves that are the problem. I think it's the seats. I do know that Honda has used stellite seats for about 15-20 years. Lead kills stellite. There's a good chance that is the issue with the Yamaha motor and leaded fuel also.
