Not to wet blanket the situation....but don't you remember "British bike" oil lakes {not leaks, lakes} under every Enfield, Triumph, BSA. Every nut or bolt rattling loose in 40 miles. And then there is the "Lucas" inherent mystical, other spectrum misadventures. In my halcyon days, I have met and failed to deal with all these issues, both metric and British Wentworth. Seems like a Gold Wing would be hard to beat with a hope to get there Triumph. Only my 2 cents.
