It's a joy to see them on the road and looking and running so well.@Rocky I would get a real kick out of seeing those old bikes still riding around in such good condition.
Much $$$ and time went into them, but once finished they are a joy to own and ride.
We/they don't thrash the crap out of them so they will run indefinitely.
Lots of fresh oil and a reasonable throttle hand keeps them like new.
