Jerry, I don't have anything that ain't got original serial number - yet. The valve work a coupla years ago repaired, not replaced, the bits in there. The next one, should I elect to have it done, would likely get me a mechanical one (so I'd take thinners) rather than a pig or other organic version (so I'd take anti-rejection drugs). Hot Dang, hey?
This visit was and is only for testing and talking - no surgery was intended, none was performed, and one of the cardiologists I talked to has an old Triumph T100 and a modern (2014) Bonneville. There's hope for me with a rider on the team.
